Database Management Systems

Database Management Systems Understanding and Applying Database Technology Michael M. Gorman The next DBMS generation is here. It contains DBMSs that look alike — on the outside. These DBMSs conform to ANSI/SQL. or ANSI/NDL, or a combination of ANSI/NDL and ANSI/SQL. This does not mean all DBMSs are the same on the inside. On the inside they perform very differently — some slow, others fast; some rudimentary, others advanced. This book is about the critical DBMS differences. Michael Gorman goes to considerable length to detail the components of a sophisticated DBMS and to provide DBMS users and evaluators the information they need to look critically at DBMS products. He covers batch, network and relational DBMSs that operate on mainframes, minicomputers and microcomputers. Gorman starts with a discussion of ANSI database standards that covers the X3H2 and X3H4 committees, DBMS standards, ANSI/SQL, ANSI/NDL, and the ANSI/IRDS. He continues with DBMS applications and components. This includes application classification, static and dynamic relationships, DBMS components and subcomponents, and DBMS requirements. This is followed by discussion of DBMS components — the logical database, the physical database, interrogation and system control. Contents: ANSI Database Standards. DBMS Applications and Components.
