Techniques for providing a unified view of a domain model to a user are described herein. In one embodiment, in response to a first search query received from a client via a first search mechanism (e.g., outside of the relational DB) for a list of persistent objects representing data entries of a relational database, it is determined whether the persistent objects have been accessed via a second search query via a second search mechanism based on an object identifier of the persistent object. If the requested persistent object has been accessed via a second search query, an identical instance of the persistent object is returned to the client as a result of the first search query. Other methods and apparatuses are also described.
