DETAILED DESCRIPTION

[0043] The following detailed description provides details of the figures and embodiments of the present application. Reference numerals and descriptions of redundant elements between figures are omitted for clarity. Terms used throughout the description are provided as examples and are not intended to be limiting. For example, the use of the term “automatic” may involve fully automatic or semi-automatic implementations involving user or administrator control over certain aspects of the implementation, depending on the desired implementation of one of ordinary skill in the art practicing implementations of the present application. Selection can be conducted by a user through a user interface or other input means, or can be implemented through a desired algorithm. Embodiments as described herein can be utilized either singularly or in combination and the functionality of the embodiments can be implemented through any means according to the desired implementations.

[0044] FIG. 1 illustrates an example problem scenario related to data management. In this example, suppose there are several factories providing Internet of Things (IoT) data to a data marketplace management system. The IoT data is processed by a Manufacturing Standard Data Model to determine the status of the factories, which can then be processed by an IoT insurer through an IoT Insurance Standard Data Model, the output of which helps to determine appropriate insurance rates by the IoT insurer.

[0045] The IoT insurer desires to scale the business and increase customers, and therefore needs to reach out to potential customers. Even if the IoT insurer wishes to search for potential customers, they do not have access to any relevant data to determine potential customers. If the IoT insurer wishes to provide an insurance premium rate from the data for potential customers, the IoT insurer may not understand what data processing techniques to use for the new customers while desiring to use present data processing for the new customers. Similarly, a factory owner may desire to sign up for IoT insurance and may not know what IoT insurance applies to his data, how to reach the IoT insurance services, what data processing is needed to obtain IoT insurance, and the costs of the IoT insurance.

[0046] FIG. 2 illustrates an example logical overview of the system in accordance with an example implementation. Meta-graph management 200 can involve a viewer 201, a meta-graph storage 202, a data flow execution engine 203, a data flow autorun engine 204, a usage record calculator 205 configured to calculate usage from using metadata, execution log 231, execution configuration 230 and autorun configuration 225, a cost calculator 206 configured to calculate costs from using metadata and execution log 231, an activity statistics calculator 207 configured to calculate activity statistics from the metadata and the execution log 231, and search engine 210. The search engine 210 can involve a data source search engine 211, a data mart search engine 212, and a data flow recommendation engine 213.

[0047] Meta-graph storage 220 can involve data processing 221, table 222, knowledge graph 223, search log 224, autorun configuration 225, various metadata such as data processing metadata 226, table metadata 227, relationship metadata 228, and public metadata 229, as well as execution configuration 230 and execution log 231. Further details of these elements are described with respect to the implementations herein.

[0048] FIG. 3 illustrates an overview of the meta-graph, in accordance with an example implementation. Specifically, the meta-graph manages relationships between data and data processing based on each column by using GraphDB, and manages input and output tables for data processing. The knowledge graph stores information in Resource Description Framework (RDF) format, and example implementations herein are explained with respect to RDF format for ease of understanding. In example implementations, the RDF-modeled Competency Index for Linked Data is used to provide a means for mapping learning resources descriptions to the competencies those resources address to assist in finding, identifying, and election resources appropriate to specific learning needs.

[0049] FIGS. 4(A) to 4(E) illustrates an example diagram of components and data flows, in accordance with an example implementation. In this example, assume there are three data sources, three data processing, one temporary data and two data marts. Referring to FIG. 3, example implementations utilize three main components which are data tables, data processing, and meta-graph. In a first scenario 400, users discover data sources form a data mart. The meta-graph manages relationships between data and data processing based on column information (meta-data). Users can search for data sources and data marts in both directions (e.g., data mart ←.fwdarw. temporary data ←.fwdarw. data source via meta-graph as illustrated at the data flow 410 for finding data sources in FIG. 4(B)) by using meta-graph.

[0050] In a second scenario 401, users create a data mart from data sources. In this scenario, user defines the data flow and executes the data flow to get a data mart as illustrated in the data flow 420 at FIG. 4(C).

[0051] In a third and fourth scenario 402, users discover data marts from a data source and users clarify the missing relationships and get a support to create the missing node. In the third scenario as illustrated in FIG. 4(D) there is a data flow 430 to search for the data mart. In the fourth scenario as illustrated in FIG. 4(E), if the meta-graph has the missing relationships between a data source and a data mart, users cannot create a data flow. Accordingly, users can clarify the missing relationships 440 and get support to create the missing relationships.

[0052] FIGS. 5(A) and 5(B) illustrate example tables and sample data, in accordance with an example implementation. Specifically, FIG. 5(A) illustrates two examples of data tables in which the column names are different, but they actually have the same meaning as illustrated at 500. In example implementations, the meta-graph uses GraphDB (including the knowledge graph) to connect the metadata relationships for these columns. FIG. 5(B) illustrates example data for the temporary data and the data mart.

[0053] FIG. 6 illustrates an example of meta-graph management for table 222, in accordance with an example implementation. The meta-graph has the ability to manage the relationship between data and data processing based on column. In this example implementation the meta-graph manages the relationships of column metadata for each table. The met-graph can manage the metadata relationships and the relationships between data and data processing based on RDF format. It is not important that the columns have the same name as opposed to having the same attributes, the same meaning, the same language, and the same data type. If the attributes/meaning/language/data type are the same, then the same data processing can be applied to such data.

[0054] FIG. 7 illustrates an example of meta-graph management for data processing 221, in accordance with an example implementation. In example implementations, the meta-graph has the ability to manage the input and output tables of data processing based on column. The meta-graph manages the relationships between a table and an input table of data processing.

[0055] FIG. 8 illustrates an example of the data flow format managed by the search log 224, execution log 231, execution configuration 230, and autorun configuration 225, in accordance with an example implementation. Meta-graph generally creates a data flow for each data mart, as illustrated in FIG. 8. The data flow is indicative of the relationships between a data source and a data mart. A data flow generally has relationships between 1 . . . N data sources and a data mart. In example implementations, the meta-graph manages column-to-column relationships in directed graphs by using the knowledge graph. For example, the meta-graph connects the relationships between table of ABC_OP110 and data processing of DP1 through a directed graph 800. Further, the meta-graph connects the relationships between table of ABC_OP120 and data processing of DP1 at 801 as well through the use of a knowledge graph. In this case, DP1 has input data for ABC_OP110 and ABC_OP120. Even if these column names are different, DP1 can execute the data processing for each table using the relationship.

[0056] In the following examples from FIGS. 9 to 16, the first scenario of FIG. 4(B) is illustrated.

[0057] FIG. 9 illustrates the example algorithm execution of the data source search engine, in accordance with an example implementation. The data source search engines are used to search for data sources from a data mart. At 900 first, user defines a root table to search for data sources. The engine then searches for execution logs to trace data flows from the data mart to data sources. At 901, if this engine detects log files, this engine conducts a depth first search for data flows from data sources to the data mart based on the log files as shown at 910 and 911. The execution log is the data flow of the data processing execution log. Therefore, this engine makes it easy to find the data flow of a defined data mart. If the engine cannot detect log files, then the engine conducts a breadth first search for data flows from the data mart to data sources as shown at 902 and 903. Specifically, the search engine searches for relationships between data processing “output” and the table as shown at 902, and searches for relationships between data processing “input” and tables as shown at 903. The process at 902 and 903 is executed recursively until a data source is located.

[0058] FIG. 10 illustrates an example interface of the data source engine, in accordance with an example implementation. In the example interface, the user can determine the search scope, and utilize the execution log, and can set the account, target component, search method, and so on in accordance with the desired implementation. As illustrated at element 1000, the user can define the search conditions (e.g., data flow depth limit, time limit, time limit/data flow, etc.) to limit the execution time. Further, if the data source search engine utilizes the execution log, the data source search engine will thereby search for relationships between the table and data processing from data sources to the root table by utilizing execution logs.

[0059] FIGS. 11(A) and 11(B) illustrate an example flow diagram for the data source search engine, in accordance with an example implementation. The flow starts at 1101, wherein the user defines a search condition to search for data sources. At 1102, a determination is made as to whether the execution log is enabled in the search condition and the root table name is in the execution log. If so (Yes), then the flow proceeds to 1103 wherein the data source search engine searches for relationships of table and data processing from data sources to the root table by using the execution logs. Otherwise (No), then the flow proceeds to 1104 to search for relationships of table and data processing from data sources to the root table to data sources.

[0060] At 1105, the data source search engine executes a search for a data flow. At 1106, the data source search engine searches for relationships of table or data processing “output” based on the table, or it searches for relationships of table or data processing “output” based on the data processing “input”. The data source engine does not only extract exact matches, but can also be modified to extract similar relationships through the use of machine learning (e.g., topic modeling, clustering, etc.) in accordance with the desired implementation.

[0061] At 1107, the data source search engine determines if the data flow is an infinite loop, if the data flow depth over the limit, or if the data flow execution time over the limit. If not (No), the flow proceeds to 1108, otherwise (Yes) the flow proceeds to 1109. At 1108, the data source search engine selects the next component to process based on a depth-first search approach. If there is a component to process (Yes), then the flow proceeds to 1106 to process the component, otherwise (No), the flow proceeds to 1109.

[0062] At 1109 if a data flow was found, then the process proceeds to 1110 to save the data flow in the search log. At 1111, if there is an additional data flow to be found (Yes), then the process repeats at 1106, otherwise (No), the process ends.

[0063] FIG. 12 illustrates an example of a graphical user interface (GUI) of the data search engine for displaying the execution result for each data flow, in accordance with an example implementation. In this example, the user clicks 1200 on the data flow, whereupon the GUI displays the properties of the data flow as shown at 1201. In this example, the search engine found a data flow, whereupon the viewer reads the flow from the search log.

[0064] In an example implementation, the estimated cost for data processing can be automatically calculated based on a selection of an execution target using execution logs. In this example, the user selects an execution target at 1202. Based on the selection, a calculation and estimation of the cost is conducted at 1203, with the results as shown for the data fee and the processing fee.

[0065] In the example of FIG. 12, the viewer can provide the relationships of the data flows. For example, at 1203, the viewer can display a solid line if the relationship is already in use based on the execution log, and at 1204, the viewer can provide a dashed line if the relationship has not yet been used based on the execution log.

[0066] FIG. 13 illustrates an example user interface when a user clicks on the table, in accordance with an example implementation. Specifically, FIG. 13 illustrates examples of properties when the user clicks on the table. These properties are managed by the meta-graph. In this example, when the user clicks on the table at 1300, the data source search engine has found ABC_OP120 table for importing new data into the data mart (Yield_App) at 1301. At 1302, the meta-graph manages the display properties of ABC_OP120. Further, as illustrated in FIG. 13, the viewer can also calculate usage records based on the execution log.

[0067] FIG. 14 illustrates examples of table properties managed by the meta-graph, in accordance with an example implementation. Specifically, FIG. 14 illustrates the example management of the display properties of ABC_OP120 by meta-graph.

[0068] FIG. 15 illustrates an example user interface displaying the data processing properties when the user clicks on the data processing 1500, in accordance with an example implementation. In the example of FIG. 15, the duplicationable field indicates whether duplication of the data processing program is approved or not. For example, encryption programs are difficult to duplicate across national borders due to data laws. If “Data Processing Duplication” of Data Flow Execution Property is Yes AND “Duplicationable” of Data Processing Property is Yes, the interface duplicates the data processing of the data flow to avoid data conflict and security risk.

[0069] In the example of FIG. 15, meta-graph manages the display properties in the meta-graph and the activity statistics (e.g., success rate, etc.) is calculated from logs (e.g., execution log, execution configuration, autorun configuration, etc.). In this example, the viewer calculates the activity statistics based on the execution log.

[0070] FIG. 16 illustrates an example user interface displaying the relationship properties when the user clicks on the relationship 1600, in accordance with an example implementation. Specifically, the properties are calculated from the logs (e.g., execution logs, execution configuration, autorun configuration, etc.). In the example of FIG. 16, a relationship property is illustrated based on the execution log.

[0071] In the following explanations for FIGS. 17 to 23, the second scenario of FIG. 4(C) is illustrated.

[0072] FIG. 17 illustrates an example interface for the execution properties when the user clicks on the data flow and the execution tab 1700, in accordance with an example implementation. The properties are set by the user, but can also be set through other techniques in accordance with the desired implementation. The validated rate indicates the percentage of successful activities in the data flow. The reuse rate indicates the percentage of reuse components in the data flow. In the example of FIG. 17, the user creates a new data flow, so the reuse rate is 0%. The properties are calculated from execution logs based on the data volume.

[0073] In the example of FIG. 17, the user renames “DSSE_Yield_App” to “Test_Yield_App” for testing purposes at 1701, wherein the user can execute the application if the data path is established at 1702.

[0074] Further, the viewer calculates a verified rate of data flow components and a reuse rate as illustrated in FIG. 17. In addition, if “Data Processing Duplication” of Data Flow Execution Property is Yes AND “Duplicationable” of Data Processing Property is Yes, then the data flow execution engine duplicates the data processing of the data flow to avoid data conflict and security risk.

[0075] FIG. 18 illustrates an example flow diagram for the data flow execution engine, in accordance with an example implementation. Specifically, FIG. 18 illustrates two main aspects of the data flow execution engine. Firstly, the engine creates new tables to store an execution result based on the data flow, as there can be data conflicts when applications use the same table. Accordingly, the data flow execution engine creates the table to avoid such a problem. Secondly, the data flow execution engine duplicates the data processing of the data flow to avoid data conflicts and security risk. If there are no conflicts or security risks, then the data flow can use the original data processing managed by another user. For example, encryption programs are difficult to duplicate across national borders under the law. The engine executes the data flow and archives log files for each component. Accordingly, this engine creates tables to avoid such a problem.

[0076] At 1800, a determination is made as to whether “Enable Execution Log” is set to Yes. If so, (Yes), then the flow proceeds to 1801, otherwise (No), the flow proceeds to 1802. At 1801, the data flow execution engine creates a log directory in execution log for the data flow. At 1802, the data flow execution engine creates new tables to store execution results based on the data flow. There can be data conflicts when applications use the same table, so the data flow execution engine creates new tables to avoid such problems at 1802. At 1803, a determination is made as to whether “Data Processing Duplication” is Yes? AND “Duplicationable” is Yes in Data Processing Property. If so (Yes), then the data flow execution engine proceeds to 1804 to duplicate the data processing of the data flow to avoid data conflict and security risk. Otherwise (No), the data flow utilizes the original data processing managed by another user.

[0077] At 1805, the data flow execution engine creates relationships between the tables and the data processing. The engine creates and saves the data flow in the Execution Config and executes the data flow. Further, if “Enable Execution Log” is Yes, the data flow execution engine archives the log for each component.

[0078] FIG. 19 illustrates an example of execution log when the user clicks on the data processing 1900 and the log tab, in accordance with an example implementation. Specifically, the viewer displays log properties by using execution logs 1901, and the user checks the program log, input data, and output data.

[0079] FIG. 20 illustrates examples of data flow properties and costs determined from the cost calculator, in accordance with an example implementation. Specifically, the viewer calculates an estimate cost and a total cost based on the selection 2000 of execution target. In this case, the viewer can calculate the total cost of this data flow because it has been processed, whereupon a pop-up can be produced to indicate “The process is finished. Click the data flow.” The cost calculator can then calculate the cost by using the execution log.

[0080] FIG. 21 illustrates an example of the autorun settings when the user clicks on the data flow and the autorun tab 2100, in accordance with an example implementation. The users can choose data-driven or batch scheduling to define execution triggers. Then, the user clicks on the create button. In example implementations, the data flow autorun engine creates event triggers for the data flow. The data flow autorun engine creates new event trigger in the data source table, or the data flow autorun engine creates a batch trigger based on “Update Frequency” of tables.

[0081] FIG. 22 illustrates an example of meta-graph with autorun settings, in accordance with an example implementation. In example implementations, the autorun engine create autorun settings in meta-graph. If the “last_update” is updated, the meta-graph management executes the data flow. The data flow execution engine executes the data flow at 2200 when meta-graph management detects an update. As shown at 2201, if the “last_update” is updated, the meta-graph management executes the data flow. Further, at 2202, the data flow execution engine executes the data flow when meta-graph management detects the specified time.

[0082] FIG. 23 illustrates an example flow diagram of the data flow autorun engine, in accordance with an example implementation. Specifically, at 2300, the data flow autorun engine saves the data flow in Autorun Config. At 2301, a determination is made as to whether the “Execution Trigger” is “Data Driven”. If so (Yes), then the flow proceeds to 2302 so that the data flow autorun engine creates a new event trigger in the data source table. Otherwise (No), the flow proceeds to 2303 wherein the data flow autorun engine create a batch trigger based on “Update Frequency” of tables. The batch trigger is the shortest period of “Update Frequency”, and the data flow autorun engine creates a new event trigger in the timer.

[0083] In the following explanations for FIGS. 24 to 25(B), the third scenario of FIG. 4(D) is illustrated.

[0084] FIG. 24 illustrates an example interface for the data mart search engine, in accordance with an example implementation. In the example of FIG. 24, the italicized content indicates the updates from the data source engine interface. The example of FIG. 24 shows the user setting the data mart search.

[0085] FIGS. 25(A) and 25(B) illustrate an example flow diagram for the data mart search engine, in accordance with an example implementation. Specifically, FIGS. 25(A) and 25(B) illustrate a flow wherein the data mart search engine searches for a data flow from a data source to data marts based on meta-graph. The flow is similar to the flow of the data source search engine as applied to data marts.

[0086] At first, a user defines a search condition to search for data marts at 2500. At 2501, a determination is made as to whether Execution Log is enabled in the search condition and the root table name is in the execution log. If so (Yes), the flow proceeds to 2502 wherein the data mart search engine searches for relationships of table and data processing from data marts to the root table using execution logs. Otherwise (No), the data mart search engine searches for relationships of table and data processing from the root table to data marts.

[0087] At 2504, the data mart search engine starts a loop to search for a data flow. At 2505, the data mart search engine searches for relationships of table or data processing “input” based on the table, or it searches for relationships of table or data processing “input” based on the data processing “output”.

[0088] At 2506, a determination is made as to whether the data flow is an infinite loop, the data flow depth is over the limit, or if the data flow execution time is over the limit. If so (Yes), the flow proceeds to 2508, otherwise (No) the flow proceeds to 2507.

[0089] At 2507, a determination is made as to whether there is a next component to process. If so (Yes), then the flow proceeds to 2505, otherwise (No) the flow proceeds to 2508.

[0090] At 2508, a determination is made as to whether the data mart search engine has found a data flow. If so (Yes), then the flow proceeds to 2509 to save the data flow in the search log, otherwise (No) the flow proceeds to 2510.

[0091] At 2510, a determination is made as to whether the data mart search engine has a next data flow to process. If so (Yes), then the flow proceeds back to 2504, otherwise (No), the flow ends.

[0092] In the following example from FIGS. 26 to 29, the fourth scenario of FIG. 4(E) is illustrated.

[0093] FIG. 26 illustrates an example of a data flow recommendation engine, in accordance with an example implementation. The data flow recommendation interface is similar to the data source search engine interface with an additional data flow recommendation.

[0094] Specifically, the data flow recommendation engine recommends a data processing to connect between tables. The data flow recommendation engine searches for a triangle relationship that contain a relationship of “table A-similar.fwdarw.table B-input.fwdarw.data processing C-output.fwdarw.table D”. If such a relationship is detected, the data flow recommendation engine recommends a data processing to connect table A and table D, and indicates that the recommended data processing and data processing C are similar.

[0095] In the example of FIG. 26, the italicized text indicates the difference between the data flow recommendation engine from the data flow search engine. The user can set the option of “Recommendation Engine”.

[0096] FIG. 27(A) illustrates an example of the data flow recommendation engine, in accordance with an example implementation. Specifically, FIG. 27(A) illustrates an example algorithm for the data flow recommendation engine. At 2701, the engine detects the relationships between the table and data processing. At 2702, the engine detects the relationship between similar tables. At 2703, the engine recommends a data processing to connect the data source and the temporary data. That is, the engine determines a data processing to connect the detected table and the next table of the similar table (Yield_App_temp). In this example, the data processing that is selected will be similar to DP1. The engine adds the recommendation node to generated data flows.

[0097] FIG. 27(B) illustrates an example flow diagram for the data flow recommendation engine, in accordance with an example implementation. After a search is invoked, a check is made at 2710 to determine whether the search is a data source search. If so (Yes), then the flow proceeds to 2711 to execute the data source search engine, otherwise (No), the flow proceeds to 2712 to execute the data mart search engine. At 2713, a determination is made as to whether the user requested a recommendation, if so (Yes), then the flow proceeds to 2714 to execute a triangle relationships detection process as illustrated in FIG. 27(A). At 2715, the data flow of the search log is updated.

[0098] To execute the triangle relationships detection as illustrated in FIG. 27(A), the data flow recommendation engine searches for a relationship of “table A-similar.fwdarw.table B-input.fwdarw.data processing C-ouput.fwdarw.table D”. If such a relationship exists, then the data flow recommendation engine recommends a data processing to connect table A and table D, and indicates that recommended data processing and data processing C are similar.

[0099] FIG. 28 illustrates an example interface of the data flow properties with the recommendation node, in accordance with an example implementation. In the example of FIG. 28, the recommendation node does not have activity logs, so the the viewer shows the estimation after the click at 2800. Further, the user cannot run a data flow because the recommendation node is not fixed in the example of FIG. 28.

[0100] In the example of FIG. 28, the viewer displays estimates if the data flow contains recommended data processing. In the example of the estimates at 2801, Nothing 01 has not been verified, so estimates are provided instead. Further, the viewer avoids the data flow execution if the data flow contains recommended data processing, as shown in the disabling of the execute button at 2802.

[0101] FIG. 29 illustrates an example creation of the data processing from the recommendation, in accordance with an example implementation. Specifically, in the example of FIG. 29 the user creates the data processing from the recommendation from the click at 2900. The user has four choices; the user can copy the data processing from DP1 to Nothing_01, leave a comment, update the input table of DP1 for adopting new data source, or update the table of new data source for adopting DP1. From one of these options, the user can create new data processing.

[0102] FIG. 30 illustrates a system involving a plurality of systems with connected sensors and a management apparatus, in accordance with an example implementation. One or more IoT systems with connected sensors or other data sources 3001-1, 3001-2, 3001-3, and 3001-4 are communicatively coupled to a network 3000 which is connected to a management apparatus 3002. The management apparatus 3002 can facilitate a data management platform as described herein. The management apparatus 3002 manages a database 3003, which contains historical data collected from the sensors of the systems 3001-1, 3001-2, 3001-3, and 3001-4, which can include labeled data and unlabeled data as received from the systems 3001-1, 3001-2, 3001-3, and 3001-4. In alternate example implementations, the data from the sensors of the systems 3001-1, 3001-2, 3001-3, 3001-4 can be stored to a central repository or central database such as proprietary databases that intake data such as enterprise resource planning systems, and the management apparatus 3002 can access or retrieve the data from the central repository or central database. Such IoT systems can include systems with databases for data received from edge devices, streaming data from robot arms with sensors, turbines with sensors, lathes with sensors, and so on in accordance with the desired implementation.
