The figure consists of two Metadata Repositories containing product metadata. The first Metadata Repository, called asdb1.myco.com, points to an Identity Management setup, which in turn communicates with a Master Repository containing Single Sign-on schema and OID schema. The Identity Management setup contains a Single Sign-On Server and OID Server. The Single Sign-On Server accesses the Single Sign-On schema and communicates with the OID Server, which accesses the OID schema. The Identity Management setup also contains DAS and DIP instances.
A middle-tier instance communicates with the Metadata Repository and the Identity Management setup.
