Oak Ridge Environmental Information System (OREIS): Phase I, System Definition Document. Environmental Restoration Program
Description: The Phase 1--System Definition Document documents the basis for establishing a consolidated environmental data base and information system for the Department of Energy Oak Ridge Field Office (OR) facilities operated by Martin Marietta Energy Systems, Inc. (Energy Systems). The Automated Data Processing System Development Methodology (ADPSDM), an Energy Systems procedure to assist in developing scientific and technical systems, was used to guide the preparation of the feasibility study and the system requirements definition, both of which are contained in this document. The Feasibility Study (Part 1) documents the existing system and data management practices and establishes and analyzes preliminary alternatives to be considered for the development of a consolidated system, i.e., the Oak Ridge Environmental Information System (OREIS). Alternatives were analyzed for technical and operational feasibility, benefits, and risks. Performance criteria used to rank alternatives included standardization, documentation, robustness, integration, reliability, and predictability. Of the three alternatives studied--request/referral, distributed, and centralized--the centralized system was selected to be most feasible because of its conformance to the performance criteria.
