Notifying a user about relevant data for opportunities includes obtaining, from a database, opportunities, the opportunities representing a complex record structure in the database, in which each of the opportunities captures a number of fields of metadata, analyzing the metadata associated with the opportunities to identify patterns for the opportunities, identifying, based on the patterns, correlations for the opportunities, and notifying, based on the correlations, the user about relevant data for the opportunities.

The present disclosure relates to merging database tables. Systems and methods may involve performing a comparison between the first set of records and the second set of records and identifying a plurality of record pairs based on the comparison. Each record pair may comprise a record in the first set of records and a record in the second set of records. In addition, A feature signature may be generated for each record pair by comparing field values in each record pair. The feature signature may be classified to identify at least one related record pair. A merged database table may be generated such that it comprises the at least one related record pair and comprises a set of unique records among selected from the first set of records and the second set of records.

Systems, methods, and devices for incrementally refreshing a materialized view are disclosed. A method includes generating a materialized view based on a source table. The method includes merging the source table and the materialized view to generate a merged table to identify whether an update has been executed on the source table that is not reflected in the materialized view. The method includes, in response to detecting an update made to the source table that is not reflected in the materialized view, applying the update to the materialized view.

A system and method for locking a charging port to charge an electric vehicle that includes determining that the electric vehicle is located within a predetermined distance of a charging station and determining when the charging port of an electric vehicle supply equipment of the charging station is attached to the electric vehicle to actively charge the electric vehicle. The system and method also include determining if the charging station accesses a parking citation associated with parking of the electric vehicle if the electric vehicle is not attached to the charging port. The system and method additionally include locking the charging port to the electric vehicle to disallow decoupling of the charging port from the electric vehicle by an unauthorized individual to avoid the parking citation.

The present disclosure provides a method including storing or accessing data representing users of first and second divisions, where the data includes first and second sets of records, receiving a query from a member associated with an organization having access privilege to the data, generating, when the query is from a member of the first division, a score that reflects a degree to which parameters of the query are similar to parameters of data representing users of the second division, where the parameters include characteristics of a family that may adopt a child, generating, when the query is from a member of the second division, a score that reflects a degree to which parameters of the query are similar to parameters of data representing users of the first division, where the parameters include characteristics of a child that may be adopted.

A system and method of query processing in a multi-level storage system having a unified table architecture. A query is received by a common query execution engine connected with the unified table architecture, the query specifying a data record. The common query execution engine performs a look-up for the data record based on the query at the first level storage structure. If the data record is not present at the first level storage structure, the common query execution engine performs separate look-ups in each of the second level storage structure and the main store.
