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.
