Design and Implementation of a Graphical User Interface for a Multimedia DatabaseManagement System

摘要

The purpose of this thesis was to design and implement a graphical user interfacefor a multimedia database management system prototype previously implemented at the Naval Postgraduate School. Because of complexity of data types and difficulty of manipulating them, it was very hard for a casual user to use the previous system. Since graphical interaction simplifies control dialogue, we designed and implemented a graphical user interface using C++ and InterViews 3.0.1 for a Sun-3 workstation under Unix X-Windows environment with mouse support. We then connected this interface to the multimedia database system prototype. Our interface supports incremental query specification using extended SQL and can be connected to database applications in several different ways. An embedded global data structure, a text file or character string can be used for connections. A second version of the interface for a Sun-4 workstation was built and connected to another database system using the character string and text file. This version demonstrated even better performance.
