Custom data

Abstract

A technique of obtaining update data from a database includes accessing configuration data associated with a particular entity in a plurality of entities. The configuration data includes a specification of how to extract a set of entity generated data records from a remote data store associated with the particular entity. The remote data store associated with the particular entity comprises common data elements shared by the plurality of entities and entity-specific data elements specified by the particular entity. It further includes determining whether values for a data field specified in the configuration data have been previously extracted from the remote data store. It further includes generating, according to the specification included in the configuration data, a query for values associated with the data field. Generating the query comprises determining a range indicator that indicates a time period of data values to be extracted. The range indicator is determined based at least in part on the determination of whether values for the data field have been previously extracted. It further includes, based at least in part on the generated query, extracting, from the remote data store, values for the data field corresponding to the determined range indicator. It further includes storing the extracted values to a data store of a central host component that provides services to the plurality of entities.
