Applying MDA in Developing Intermediary Service for Data Retrieval

In this paper, service for data retrieval from existing library management system is described. This service intermediates between library management system which provides data and system which requires that data. The main idea is that this service should support various protocols for data retrieval. Also, this service should be flexible for future update and simple enough for integration into any library management system. Service presented in this paper is developed by using Model Driven Architecture (MDA) approach. Different models (proposed by MDA) of this service are presented in this paper. Models are presented by using UML 2.0 specification. Transformations from models to Java programming code are done by using AndroMDA framework.
