Entity-Relationship diagram of MODB. The organization of data contained within MODB is centered on the unique morpholino sequence. Tables pertaining to the morpholino-specific information are located in the upper left corner (solid box). The tables in the lower left corner establish the relations between laboratories, users and security level designation (dashed line box). The tables on the right half of the diagram represent the tests and test components such as anatomical structure, screen and defect observed (unboxed area).
