This graphic represents a Topology where the Client, the Control Center Service, and the Oracle Database are each installed on a different computer.
The Oracle Database is installed on the server computer, and it contains a Repository, a Target Schema, Source Schema 1 and Source Schema 2.
The Repository contains at least one Workspace, which contains Audit Tables, TS1 (with Map, T1, and T2), SS1 (with T1, and T2), and SS2 (with T1, and T2).
The Target Schema contains a Map, T1, and T2.
The Source Schema 1 contains S1, and S2.
The Source Schema 2 contains S1, and S2.
The OWB Control Center Service is installed on its own computer; it deploys and executes on the Map of the Target Schema in the Oracle Database on the server computer.
The Design Center is installed on the client computer. It manages the design inside the Repository that is in the Oracle Database on the server computer. It also deploys and executes on the OWB Control Center Service, which is installed on its own computer.
The Local OC4J service is installed on the client computer. It contains the Browser Server. It reports on the Repository in the Oracle Database that is on the server computer, and it reports on the Audit Tables that are in the Workspace of that Repository (on the server computer). It also receives and updates the OWB Browser's Design Reports and Audit Reports, on the client computer.
