A Cardiovascular Research Database System is being developed at Toronto General Hospital on a Varian V-76 minicomputer. The system utilizes the TOTAL Database Management System as a manager of the internal network structure of the database and the data dictionary/ directory. The system was designed to achieve data independence as defined by the ANSI/X3/SPARC/SGDBMS committee. This paper will describe the first phase of this project.
