Abstract: Systems and methods to copy a plurality of source data records of a source client to a target client include deletion of a first set of target data records of a plurality of target data records associated with the target client, each of the first set associated with a key which is not identical to any key of a plurality of source data records, insertion of a second set of source data records into the plurality of target data records, each of the second set of source data records associated with a key which is not identical to any key of the plurality of target data records, and update of a third set of target data records associated with a key which matches a key of one of the fourth set of source data records and which is different from one of the fourth set of source data records.

Abstract: The present disclosure relates to computer-implemented methods, software, and systems for generating a hierarchy of metadata tables for a database comprising containers including tables. The tables are identified by table names and assigned to containers. A first table is assigned to two containers and may define two table instances of the first table. The hierarchy of metadata tables includes a first metadata table defining mappings between container identifiers, table names, table sections, and unique identifiers for corresponding data within table sections of table instances defined with the table names mapped to the container identifiers. In response to receiving a request to generate a replication of table content, a second metadata table is generated to identify a unique set of table instances from the set of the containers based on evaluating the first metadata table. The unique set of table instances comprises data from the database storage without repetition.

Abstract: The present disclosure relates to computer-implemented methods, software, and systems for managing data replication between different source sections and target sections in response to received copy instructions associated with copy profiles. In response to evaluating statistical metadata identifying whether data records in relation to at least one client are included for a table from a first set of tables, a first subset of tables from the first set of tables is determined. In response to evaluating update metadata defining latest updates of tables from the first subset of tables, a second subset of tables from the first subset of tables is determined that defines tables that include updated data records relevant for copying. The second subset tables are iteratively evaluated to define corresponding operations to be performed for tables at the target section and at the source section in the database in relation to the requested copy operation.
