| Summary: | Approved for public release; distribution is unlimited === Traditional approaches to database design and implementation involve text-oriented data access with their inherent lack of modularity, extensibility, and modifiability. An alternative to this traditional approach is using visual interface for the design and implementation of databases. This alternative approach involved using software development tools(toolkits) to ensure modularity, extensibility and modifiability. To study the effectiveness of using visual interfaces, we have designed and implemented a sample application using KnoeldgePro(Windows), a tool for rapid application development under Windows.
