In this paper we present a data retrieval and information visualisation tool, named the Object-Oriented Graph Editor (OOGE). The OOGE is designed to represent information of special kinds of system, Hierarchical Systems or Object-Oriented Systems. These systems can be represented by Object-Oriented Graph, in which nodes have attributes and their connections are constraint-based. The editor presented provides a friendly graphical user interface for users to define any class of nodes of the OO Systems and to draw the 00 Graph based upon the user-defined node classes. The validity of proposed system can be checked against the set of constraints that based on the attributes of the user-defined classes.
