| Summary: | 碩士 === 國立中正大學 === 資訊工程研究所 === 90 === We describe the implementation of a simple user interface for our object-oriented database for the interactive creation and editing of persistent classes, objects, and their binary relations. This client interface can run remotely, and uses RMI (Remote Method Invocation) calls to query or edit data on one or more servers. The queries could be saved in the form of XdbQL expressions (short for X Database query language expressions) under a user-provided name. The query follows binary relations from the user’s home to the appropriate objects, selecting appropriate objects along the way either by using the mouse or by assigning ranges to attributes. All interactions are selection-driven, so the users of the system do not need to remember what classes and binary relations are stored in the database.
