Module: catalogs, procs query lang., Procs interface, access and data buffering, controlling cuncurrency, handling data recovery and security; interfacing: interface for the integrated system) 2. Tool Developers : The people who design and implement tools to support the DBMS software. (Tools to improve database performance, operational monitoring tools for databases, etc.) 3. Operators dan maintenance personnel : The personnel administrator who will be responsible course of database operations including maintenance (hardware / software) DBMS

  4. Application Salary Report DBMS Application Trainning Report Database Query Update
