Abstract
Currently, there are two approaches to control the database concurrency: the two-phase locking approach and the timestamp approach. In this paper, we introduce a new approach which will increase the output of the distributed database management system, DDBMS. In this new system, instead of preventing users from modifying data while other users read them, DDBMS will create virtual tables for those database readers. Therefore, those data values can be accessed in read mode by multiple users and be access in write mode by a user, simultaneously.
