Abstract

A database access controlling system controls the access to a database from a database access layer in an application, especially a relational database, with data sets that are being accessed concurrently by reading and writing transactions. The present system performs changes on the data by a writing transaction that place the changed data in a marked state. The changed data in the marked state enables concurrent transactions to recognize that the data has just been changed.
