Techniques for database and file management herein include a processor and a memory device storing instructions that cause the processor to perform operations comprising creating a request based on an extensible markup language (XML) or an interpreted scripting language object, wherein the request comprises unauthenticated data for validation. The operations can also include transmitting the request to a remote device), updating metadata corresponding to the request to indicate the successful validation by the remote device, validating a response file, and detecting a discrepancy between the unauthenticated data and the authenticated data accessible by the remote device. Additionally, the operations include obtaining correction data to resolve the discrepancy, and executing a transaction based on the request and the correction data.

The present disclosure relates to database technology and in particular to dynamically updating and customizing database partitions. A computer-implemented engine is disclosed for identifying and retrieving a number of data records applicable to generate a response to a request, the engine having access to at least two partitions. Partition statistics are generated indicating correlations between the data records and, based on that partition statistics, the data records having the strongest correlation with each other are relocated to partitions so that the number of partitions which have to be queried in order to generate a response to a data request is minimized. Furthermore, the computational load caused when generating responses is more equally distributed across the partitions.

Example embodiments relate to a system to generate and cause display of a specially configured graphical user interface to receive and present collections of images. According to certain example embodiments, an image analysis system: receives an image file from a client device; generates a hash value based on the image file; performs a comparison of the hash value with a list that comprises a collection of hash values; identifies a match to the hash value among the collection of hash values; assigns a label to the image file in response to identifying the match among the collection of image files from the list; and indexes the image file at a memory location identified by the label assigned to the image file.

A request may be received to transfer from a first entity to a second entity a right related to a digital asset stored in an on-demand database system. The on-demand database system may provide computing services to a plurality of entities via the internet. A token associated with the digital asset may be identified. The token may being included in a smart contract recorded within a distributed trust ledger and may be owned by a first distributed trust ledger account. The smart contract may be executed within the distributed trust ledger to record a transfer of the token from the first distributed trust ledger account to a second distributed trust ledger account. The on-demand database system may be updated to include one or more database entries reflecting the recorded transfer.

Systems and methods to read records of a data staging table, where each record of the data staging table is associated with a package identifier, a key value of a record of a first database table, values of one or more non-key fields of the record of the first database table, and a database operation, include reading of one or more records of the data staging table, each of the read one or more records associated with a package identifier indicating the record is not being processed, and not including a same key value as any other record of the data staging table associated with a package identifier indicating the record is being processed, updating the package identifier of each of the read records of the data staging table to a first package identifier indicating that the record is being processed, creating a transaction record of a transaction queue associating the data staging table and the first package identifier, determining that the read one or more records have been processed, and, in response to the determination, deleting the one or more read rows from the data staging table and the transaction record.

Example embodiments facilitate orchestrating changes of data made (and/or actions specified for execution) in a client-side program with changes of corresponding data made in one or more server-side data objects. An example method includes structuring one or more worksheet relationships between one or more worksheets of a client-side spreadsheet in accordance with one or more data object relationships of one or more data objects of a server-side data structure; determining that one or more operations have been selected for performing on data of one or more of the worksheets; detecting user input operative to initiate performance of the one or more operations; and initiating implementation of the one or more operations (e.g., CRUD (Create, Read, Update, Delete) operations) in accordance with the one or more worksheet relationships and the one or more data object relationships (e.g., hierarchical relationships). A spreadsheet add-in may issue request messages to web services tasked with completing the one or more operations.

Systems and methods for generating assessments based on construction site images are provided. For example, image data captured from a construction site using at least one image sensor may be obtained. Further, at least one electronic record associated with the construction site may be obtained. The image data and the at least one electronic record may be analyzed to generate at least one assessment related to the construction site. For example, the image data may be analyzed to identify at least one discrepancy between the at least one electronic record and the construction site, and the identified at least one discrepancy may be used in the generation of the at least one assessment.

Methods and systems for improved creation, monitoring, and updating of energy transactions are provided. In one embodiment, a method is provided that includes receiving a request to originate a contract for an energy transaction. Transaction information concerning the energy transaction may be received and may identify a type of energy resource and parties for the energy transaction. A requirement for the energy transaction may be identified within the contract codex and at least one condition may be determined based on the requirement. An updated contract may be generated by adding the at least one condition to the contract. Information regarding the updated contract may be stored on the distributed ledger.

The present disclosure relates to systems and methods for creating and using personas. The method includes receiving a first set of input signals associated with data from one or more source; receiving a second set of input signals associated with data from one or more source; converting the first set of input signals and the second set of input signals to a wavelet; constructing a persona based on the wavelet; storing the persona in a ledger; receiving a request for a decision related to a transaction; converting the request to a new wavelet; determining a difference between the new wavelet and the stored persona; generating a score based on the difference; and authorizing the transaction based on the score.

Provided is an apparatus for deriving a social relation between accounts based on a transaction ledger, which includes: a data storage unit storing account information, software for deriving an inter-account social relation, and inter-account social relation information; and a processor deriving the social relation between the accounts based on a transaction ledger generated by transactions among users with the accounts.
