Janus Data Model

The Janus database is based on a relational data model consisting of over 450 tables. The complete data model is too big to view on a computer monitor or on paper. For ease of viewing and analysis the model has been divided into several subject areas corresponding to the scientific laboratories and data types. The data model was originally developed using System Architect and is now maintained using Computer Associates ERwin data modeling software. For any question regarding the data model please contact the Data Librarian.
