Summary: | An interface system was proposed that would give the user the ability to query a database, regardless of the host data base management systems, as long as the user's computer could communicate with the database's host computer. Investigations were made into existing query resolution systems, and query definition structures and universal data manipulation languages were researched. With this background, a base query resolution system was chosen, and additional capabilities for an improved final query definition structure and a universal data manipulation language were proposed. In this project, the syntactic analysis part of the query resolution system was implemented. The use of the improved final query definition structure within the query resolution system was defined, and a high level design of the UNIVERSAL-DML (including a pseudo-code representation of the resultant application program) is presented.
