Abstract :
An SQL-based system is described that supports complex objects, nonnormalized (NF2) relations, arrays, matrices, ordered lists, and versions. Both object-oriented and data views of a relational database are supported. The system supports the integration of OR/MS (operations research and management science) modeling with corporate databases. It is part of the ASUMMS model management system. The data subsystem includes a fully-fledged commercial database system. Integration and compatibility allow pure database applications (e.g. invoices and customer payments) running on 1NF databases to be processed concurrently with quantitative modeling tasks on the same data. The NF 2 and complex object extensions provide for a common data model for data and models, and the implementation architecture supports both 1NF and NF2 database management systems
