Army Nonprogrammer System for Working Encyclopedia Requests. Phase 3A report

Abstract

The report discusses a set of data management tools and distributed query processing modules developed and/or enhanced during a 9 month effort, the third phase of a four phase effort. In Phases I and II of the answer program, we emphasized the development of data administration tools to aid in the process of creating and maintaining a heterogeneous distributed system. The schema integrator creates integrated schemas from individual schemas and data administrator assertions about individual schema relationships. The integrated schemas can be used as the basis of distributed query processing by providing a global definition of available data and static mappings to local systems. The schema integrator reads and writes schemas to and from an IRDS repository, an ANSI and FIPS standard for data definition repositories. ALL ANSWER tools will eventually share information through the IRDS repository.
