CEWES MSRC Web-Linked Database Projects Developed by NPAC

This report summarizes two focused efforts with a common theme of coupling commercial database technology with the world-wide web to facilitate the presentation and management of large information spaces. The two project titles are “Web-Linked Databases for Domain-Specific Information Repositories” and “Interfacing Databases and the Web: Management of Large WWW Sites Using Commercial Database Technology”. Both projects utilize the Oracle7 relational database system, the Oracle Context Option and the Oracle Web Server. The services provided can be accessed using any standard web browser. Web-Linked Database For Domain-Specific Information Repositories Introduction This project deals with searching out specific useful information from the large amounts of information available on World Wide Web. Along with the growth of Internet, the amount of information on the WWW became increasingly large and it’s hard for users to obtain what they want from the huge volume of information in a way that’s quick, precise and efficient. This project provides an efficient way for users to locate specific information from the glut of information available on the web. It is a web search engine which centralizes and indexes information about grid generation technologies (as used in computational fluid dynamics, structural mechanics, and other fields). Grid generation expert Joe Thompson of Mississippi State University provided some of the initial information (URLs of major grid generation WWW sites) used to seed the search engine. Components And Implementations At the highest level, the Grid Search System consists of three parts: Robot, Database and Web Interface.
