I am using the Swagger-UI application for API. Eventhough it supports both Relational and Non-Realational sources. We have information only for Preparing a test data for Non-relational source in the userguide of CA TDM 4.4. Im strucking with registering the tables from the database.
It will be useful if we have a document for relational sources also.
Please let let us know what product you are using. This community is for the CA API Gateway and the question you have seems to be related not to that technology.
