Abstract

The Operations and Maintenance Business Information Link (OMBIL) is a relational data warehouse that provides users with direct access to performance-based management, budget, and financial information in a graphic format for review and analysis. This paper examines the corporate data models constructed to support the successful deployment of the physical system (business application). The business application data entry fields are also examined for comparison to the decision support component built into OMBIL. This analysis paper compares data model complexity to performance measures that are reported to the Office of Management and Budget and for use in determining the overall effectiveness of the Corps’ civilian water resources management mission. The research findings will provide an analysis baseline for further examination of the maintainability and reliability of conceptual data models and assist in refining established data quality frameworks.
