Abstract
Efficiency is one of the most crucial factors to be sought in the design of a DBMS for engineering data, because the data size can be very large. Efficient data handling is usually achieved at the cost of flexibility of a system. It is hard to facilitate evolution of applications. GDL (Graph Data Language) presented here aims at a practical solution of efficiency and data independence problem, by allowing a user to control effective database design in terms of a high level data language. This paper describes an overview of GDL. The data model is formulated as a labelled directed graph (i.e., a general network structure). The characteristics of GDL include operations on graphs, dynamic type handling and structured concise data manipulation statements.
