Abstract

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.

Claims

1. A machine-implemented method, comprising:

receiving a first search query for a list of persistent objects representing data entries of a relational database from a client via a first query and retrieval application programming interface (API), the first search query being a full-text search query having one or more keywords;

determining whether each of the persistent objects has been accessed via a second search query previously received via a second query and retrieval API based on object identifiers of the persistent objects, the second search query being a structured query language (SQL) query; and

returning, via the first query and retrieval API, an identical instance of the one or more persistent objects to the client as a result of the first search query if the one or more persistent objects have been previously accessed via the second search query, the identical instance of the one or more persistent objects being returned to the client without accessing the relational database.

2. The method of claim 1, wherein the second search query includes the object identifiers identifying the queried persistent objects.

3. The method of claim 2, wherein the object identifiers of the second search query correspond to object identifiers in a list or a subset of the list retrieved from the first full-text search query, wherein the list includes one or more documents containing at least one of the one or more keywords.

4. The method of claim 3, wherein the list of the one or more documents is obtained by searching the one or more keywords within an index directory.

5. The method of claim 1, wherein determining whether each of the persistent objects has been accessed via the second search query is further based on an object type and identifier of a corresponding persistent object.

6. A non-transitory machine-readable medium having instructions stored therein, which when executed by a machine, cause the machine to perform a method, the method comprising:

receiving a first search query for a list of persistent objects representing data entries of a relational database from a client via a first query and retrieval application programming interface (API), the first search query being a full-text search query having one or more keywords;

determining whether each of the persistent objects has been accessed via a second search query previously received via a second query and retrieval API based on object identifiers of the persistent objects, the second search query being a structured query language (SQL) query; and

returning, via the first query and retrieval API, an identical instance of the one or ore persistent objects to the client as a result of the first search query if the one or more persistent objects have been previously accessed via the second search query, the identical instance of the one or more persistent objects being returned to the client without accessing the relational database.

7. The machine-readable medium of claim 6, wherein the second search query includes the object identifiers identifying the queried persistent objects.

8. The machine-readable medium of claim 7, wherein the object identifiers of the second search query correspond to object identifiers in a list or a subset of the list retrieved from the first full-text search query, wherein the list includes one or more documents containing at least one of the one or more keywords.

9. The machine-readable medium of claim 8, wherein the list of the one or more documents is obtained by searching the one or more keywords within an index directory.

10. The machine-readable medium of claim 6, wherein determining whether each of the persistent objects has been accessed via the second search query is further based on an object type and identifier of a corresponding persistent object.

11. A data processing system, comprising:

a processor; and

a memory coupled to the processor for storing instructions, which when executed from the memory, cause the processor to

receive a first search query for a list of persistent objects representing data entries of a relational database from a client via a first query and retrieval application programming interface (API), the first search query being a full-text search query having one or more keywords;

determine whether each of the persistent objects has been accessed via a second search query previously received via a second query and retrieval API based on object identifiers of the persistent objects, the second search query being a structured query language (SQL) query; and

return, via the first query and retrieval API, an identical instance of the one or more persistent objects to the client as a result of the first search query if the one or more persistent objects have been previously accessed via the second search query, the identical instance of the one or more persistent objects being returned to the client without accessing the relational database.

12. The system of claim 11, wherein the second search query includes the object identifiers identifying the queried persistent objects.

13. The system of claim 12, wherein the object identifiers of the second search query correspond to object identifiers in a list or a subset of the list retrieved from the first full-text search query, wherein the list includes one or more documents containing at least one of the one or more keywords.

14. The system of claim 13, wherein the list of the one or more documents is obtained by searching the one or more keywords within an index directory.

15. The system of claim 11, wherein the processor is caused to determine whether each of the persistent objects has been accessed via the second search query based on an object type and identifier of a corresponding persistent object.
