A method enables on-demand delivery of data from a plurality of heterogeneous external data sources to a data analytics tool. With a mapping of one or more identified data connectors, a no-code client query, as formulated in a first data model, is dynamically translated to one or more external queries formulated in one or more alternate data models of the heterogeneous external data sources. With the mappings of the one or more identified connectors, each response to the one or more external queries is reformulated from the one or more alternate data models to the first data model to yield one or more client query results objects. The client query results objects are sent to the data analytics tool.

Disclosed herein is a system and method to any two or more MLMs to be merged into a multiline MLM system despite having different commission structures. Each member of the original MLMs is able to maintain their existing downlines without any changes. Further the existing MLM members have full access to the multi-line MLM commission structure, for example, a member of a binary MLM may now add a 3rd, 4th, 5th, etc. line if they choose. The multiline commission plan will be different than the commission plans from any of the original MLMs but this change should not affect the income of a large portion of users, and users that are affected by the changeover can be compensated or made whole on an individual level. In addition to this multiline commission plan, the commission structure of the original MLMs has been broken into several separate ‘types’ which together form an MLM system. These ‘types’ include the income received from downline commission based on position and the income received based on enrolling a member in the MLM, also known as sponsorship. This system is one that may be hosted on the internet or cloud computing services and may provide remote access to the newly formed MLMs. The system will provide essential services to the MLMs such as databasing, commission calculation, and commission structure modification, for free or for a fee. MLMs, their agents, executives, employees, members, and other entities selected by the MLM will be able to access the system using secure credentials.

A digital security system can store data associated with entities in resolver trees. If the digital security system determines that two resolver trees are likely representing the same entity, the digital security system can use a merge operation to merge the resolver trees into a single resolver tree that represents the entity. The single resolver tree can include a merge node indicating a merge identifier of the merge operation. Nodes containing information merged into the resolver tree from another resolver tree during the merge operation can be tagged with the corresponding merge identifier. Accordingly, if the merge operation is to be undone, for instance if subsequent information indicates that the entries are likely separate entities, the resolver tree can be unmerged and the nodes tagged with the merge identifier can be restored to a separate resolver tree.

Techniques are described for responding to aggregate queries using optimizer statistics already available in the data dictionary of the database in which the database object targeting by the aggregate query resides, without the user creating any additional objects (e.g. materialized views) and without requiring the objects to be loaded into volatile memory in a columnar fashion. The user query is rewritten to produce a transformed query that targets the dictionary tables to form the aggregate result without scanning the user tables. “Accuracy indicators” may be maintained to indicate whether those statistics are accurate. Only accurate statistics are used to answer queries that require accurate answers. The accuracy check can be made during runtime, allowing the query plan of the transformed query to be used regardless of the accuracy of the statistics. For queries that request approximations, inaccurate statistics may be used so long as the statistics are “accurate enough”.

A data management system includes a data reconciliation engine that identifies data sources that contain data records referencing a resource and determines whether each of the identified data sources is a creative data source or an additive data source. When all of the identified data sources are additive data sources, the reconciliation engine terminates a data reconciliation process. When all of the identified data sources are not additive data sources, the reconciliation engine finds a first creative data source from among the identified data sources, and initiates the data reconciliation process by merging data from the identified data sources including the first creative data source, one data source-by-one data source, into a reconciled data record.

A method for processing sensor data includes assessing the sensor data of a sensor using metadata of the sensor as well as sensor data of at least one additional sensor using the metadata of the additional sensor, in order to receive assessed sensor data of the sensors. The method further includes merging the assessed sensor data in order to receive merged sensor data.
