Data base administration: classical pattern, some experiences and trends

This three part paper covers the growth and classical patterns of data base administration along with a survey of some currently practicing data base administrators. As a result, some trends and evolutions of the data base administrator position are presented. After a brief historical introduction, the paper first sets forth basic definitions and organizational considerations for the DBA function. Interfaces, both internal and external are defined and the associated problems are discussed. The functions and responsibilities of the DBA are presented along with the tools available for carrying them out as recommended by various committees including CODASYL, GUIDE/SHARE and other reports. Then, a survey of organizations utilizing data base administrators is presented. The survey looks at organizations of varying sizes and commitments to data base technology. The results of the survey try to show how the previous recommendations are reflected in reality. An attempt to rationalize the plans and the actual status of the DBA in an organization is carried out. Finally, from the survey results and from projections provided by the data base administrators themselves, some trends in the evolution of their functions are outlined. In light of these projections an attempt is made to review some of the recommendations currently put forward.
