AN EXPERIENCE WITH CASE TOOL SUPPORT FOR FINANCIAL PRODUCT DESIGN

The development of enterprise-wide information systems is a key success factor for the banking industry. This paper addresses the problems and benefits resulting from the use of a well-known CASE tool for the design of an information system to support product design in financial institutions. One goal of the project was to build an information system to allow the design of products not limited to existing lines of business. The design process is based on an enterprise-wide data model, which is stored in the tool's encyclopedia and which provides a binding framework for the design process. During the design phase, we discovered that the semantic power of the relational model was not sufficient for our purposes. Object-oriented or deductive database systems would have been helpful. The CASE tool did not sufficiently support nonstandard database models on the conceptual level.
