Example text

An individual with systems programming background and experience in system software support is the most likely candidate for DBMS specialist. However, DBMS training and experience are necessary before one can function effectively in this role. 4. Data Dictionary Specialist The data dictionary specialist is responsible for creating and maintaining a dictionary of the data elements included in the organization's data base(s). A name, description, edit specifications, access rules, and other information on usage must be kept for each element.

In organizations in which only the system development function has been decentralized, two other DBA structures are possible. 7). Since the system development groups now report to operational management at their decentralized locations, the DBA'S level is of crucial importance to the success of the function. The management DBA is most effective in this situation. Second, the DBA staff can be partitioned and assigned in response to the decentralized environment. 8). For best results, the data base design staff would report directly to operational management at their location, with a dotted line responsibility to the manager of DBA.

Thus DBA assumes a project/support or functional/support position within the data processing organization. During this phase the DBA concentrates on developmental tasks, such as designing the data base and developing procedures for backup and recovery. Maintenance of the data dictionary, of data base descriptions, and of the DBMS also begins during this stage. As a result, the DBA staff may grow in size and may assume a functional structure internally. In many organizations the DBA group does not exist until the initiation stage.
