Entity Relationship Diagrams

An entity relationship diagram (ERD) represents database tables and the logical relationships between them. ERDs for the database in which framework data will be stored are shown below. Only primary and foreign keys, and other fields essential to structure, are included.

These are works in progress, and will continue to evolve as the database and API continue to be developed.

Software

NERIS uses a PostgresSQL database. It is defined and managed primarily with the Python object relational mapper SQLAlchemy.
