Research quality data from geotechnical tests conducted at the designated National Geotechnical Experimentation Sites (NGES) are currently available in a database accessible through the Internet. The data include general site information, stratigraphy, laboratory and in situ test details. The database is structured to follow the rules of Relations Database Management Systems (RDBMS). The database resides in a Unix based Sun Solaris server and the database engine is Sybase RDBMS. The NGES database user interface query application has been developed for the Internet using Java as the programming language and runs under any Internet capable browser. The application uses Java applets to communicate with the database server. The interface comes with user-friendly query capabilities along with graphic display of various results in tabular and chart forms. The user community includes researchers, students, and practicing engineers in geotechnical and geo-related fields.
