The objective of this task is to define one or more apse(s) for the airmics command based on the development, enhancement, and maintenance characteristics for management information systems (miss). Apse(s) will be formed for these three major domains, with emphasis on large, medium, and small systems. During phase i, research is performed to identify existing case tools, environments, methodologies, and a prototype "how they all fit together" database system. The prototype database system will enable the automated selection of an appropriate apse(s) for a specified mis/"business data processing" domain and then associate specific tools and methods with this apse(s). Phase ii will be to demonstrate the selected apse(s) and upgrade the prototype database system to an operational system.
