This paper introduces a graph-oriented model for the conceptual level design of large, complex information systems. This has been shown to be highly effective to the system designer from the perspectives of maintainability and upgradability. Basically due to the flat structure and the lack of holding multidimensional data, the relational model does not provide a structural approach to the system designer. The alternative object oriented model offers the structured approach but also is not able to describe various intermodular relationships spread over the same or different levels within a data model. The graph data model allows dynamic regrouping of related entities at the designers' level. We have proposed an appropriate data structure and the corresponding DDL has been developed. Test runs on a simulated environment further establish its computational efficiency. © 2000 IEEE.

Conceptual level graph theoretic design and development of complex information system

Proceedings - International Conference on Information Technology: Coding and Computing, ITCC 2000

In an effort to design and develop a suitable platform for the next generation information systems, a new Graph Object Oriented database Model (GOOM) is proposed. In fact, the proposed model in its present definition is an improvement of our earlier work (S. Choudhury et al., 1998; 2000). The evolution is found to be absolutely essential in the interest of implementing the model and towards building a reliable Graph Query Language (GQL). We have introduced the concept of encapsulating homogeneous entities into semantic group while permitting the declaration of relationships amongst different semantic groups from various user-defined views. The proposed model aims at extracting the positive features of both object and relational data models besides providing a structured graphic representation. The paper emphasizes the mathematical foundation of the proposed graph language. In fact, the proposed GQL maintains a very similar interface to that of widely accepted SQL. © 2001 IEEE.
