An Active Conceptual Model for Fixed Income Securities Analysis for Multiple Financial Institutions

摘要

The practical implementation and use of a mediator for fixed income securities analysis demonstrated the potential for extending the application of conceptual modeling from the system design stage to providing query access to both data and computational resources. The mediator product was designed as a general interpretive engine specialized and controlled by the declarative knowledge from the conceptual model. The fixed income conceptual model included securities ranging in complexity from Treasury bills to collateralized mortgage obligations, as well as standard and proprietary analytic methodologies and calculations. All information, whether computed or retrieved from databases, was offered to clients in the form of attributes of conceptual entities. Client preference entities and attributes were used to control selection among conceptually interchangeable source data and procedural components. Experience from this implementation provides insight into the requirements for successful application of a conceptual model in mediating among heterogeneous, autonomous users and information resources.
