The Oracle Enterprise Repository (OER) is a service repository that, in the tradition of SOA service repositories, contains detailed information on the services describing the related application(s).
Services are not just web services. A service can be an anything from a web service to Oracle Sales Cloud as a whole.
The OER therefore contains a wealth of information, more than you probably would imagine. From high level entity relationship diagrams to detailed database and column descriptions.
For each of the returned results, there is always a list of different versions for which this documentation exists. Make sure you check out the version that matches the version you are using.
Here are a few examples of what you can find when browsing through the OER, but there is much MUCH more. And this is a public website available not just to Oracle employees, but to customers and partners too !

You will discover all the technical and logical data diagrams
2. web service documentation
e.g. search for ‘estimated compensation’, type ‘ADF Service’, product family ‘Incentive Compensation’.
