Tools supporting database query and report generation use mainframe, minicomputer and microcomputer-based databases. FOCUS, RAMIS, and NOMAD II, for example, are mainframe-
based languages supporting database query, report generation, and simple analysis. FOCUS and RAMIS are also available in PC versions. Ingres, Oracle and Informix are database languages on mainframes, minicomputers and microcomputers. Managers frequently use microcomputer-based database tools such as MS-Access and R: base 5000.
