Entity Relationship Diagrams for AtoM
This page contains downloadable versions of Entity Relationship diagrams that have been generated over time from AtoM's relational database. An ER diagram is a specialized type of illustration that can be used to express the entities, attributes, and relationships comprising a relational database.
With each major release of AtoM, the database is likely to change. Here we will add historical and (as we are able) current versions of the ER diagrams from AtoM to assist new developers in understanding how AtoM is structured.
These diagrams have often been generated by developers during the development process - that is, between stable releases. Note that they are not definitive, and the database schema may be different in the subsequent version.
