Abstract: Updating multiple data records in a database system with at least one database and a first server comprises creating a first session and loading, within the first session, the multiple data records stored by the database into a memory of the first server. Update at least a first and a second of the multiple data records during the first session in the memory of the first server. A database transaction mechanism writes back the multiple data records after updating the at least first and second data records to the database which insures that either all or none of the updated database records are committed. The database transaction mechanism includes a write lock over the first and second data records stored in the database.

Abstract: Methods, systems, and computer program products for data processing utilizing an asynchronous communication repository. Instructions are received at a first event publisher to publish a first dataset. The instructions include a directive to retrieve a second dataset published by a second event publisher, a directive to determine a first metadata structure including attributes describing the first dataset, and a directive to send the first metadata structure to an asynchronous communication repository for storage. A second metadata structure describing the second dataset is received at the first event publisher from the asynchronous communication repository using an asynchronous communication protocol. The second dataset is retrieved at the first event publisher from the second event publisher. The first dataset is generated based on the second dataset. The first metadata structure is determined based on the first dataset.
