SILO-AWARE DATABASES

1 . A computer-implemented method comprising:

forming a database table proxy for a logical database;

assigning one or more database silos to the database table proxy;

defining a default database silo from the one or more database silos for the database table proxy; and

accessing, using at least one processor, a database silo of the database table proxy corresponding to an application requesting access to the logical database at a database engine.

2 . The computer-implemented method of claim 1 , further comprising:

storing a relationship between the one or more database silos and the database table proxy in a database table proxy metadata repository.

3 . The computer-implemented method of claim 1 , further comprising:

assigning the database silo to the application requesting access to the logical database in a database table proxy session information table.

4 . The computer-implemented method of claim 1 , further comprising:

accessing the default database silo when the application requesting access to the logical database does not specify any database silo.

5 . The computer-implemented method of claim 1 , further comprising:

receiving a request to access the logical database from the application;

identifying a database silo from the request; and

accessing the identified database silo from the request for the application.

6 . The computer-implemented method of claim 1 , further comprising:

receiving a request to access the logical database from the application;

determining whether the request identifies a database silo; and

identifying the database silo corresponding to the request using a database table proxy session information table when the request does not identify the database silo.

7 . The computer-implemented method of claim 1 , further comprising:

manipulating data in the database silo in response to a request of the application without affecting data in other database silos of the database table proxy.

8 . The computer-implemented method of claim 1 , wherein the database silo is stored in a permanent storage device or a non-permanent storage device.

9 . The computer-implemented method of claim 1 , further comprising:

defining a database silo with a database silo name, whether data stored in the database silo is to be stored permanently, and whether the database silo can be shared between applications.

10 . The computer-implemented method of claim 9 , further comprising:

deleting a content of the database silo after the application terminates when the database silo accessed indicates that the data is to not to be stored permanently.

11 . A system comprising:

a storage device configured to store a logical database; and

a processing device comprising a database engine configured to form a database table proxy as the logical database, assign one or more database silos to the database table proxy, define a default database silo from the one or more database silos for the database table proxy, and access a database silo of the database table proxy corresponding to an application requesting access to the logical database.

12 . The system of claim 11 , wherein the database engine is further configured to store a relationship between the one or more database silos and the database table proxy in a database table proxy metadata repository.

13 . The system of claim 11 , wherein the database engine is further configured to assign the database silo to the application requesting access to the logical database in a database table proxy session information table.

14 . The system of claim 11 , wherein the database engine is further configured to access the default database silo when the application requesting access to the logical database does not specify any database silo.

15 . The system of claim 11 , wherein the database engine is further configured to receive a request to access the logical database from the application, to identify a database silo from the request, to access the identified database silo from the request for the application.

16 . The system of claim 11 , wherein the database engine is further configured to receive a request to access the logical database from the application, to determine whether the request identifies a database silo, and identify the database silo corresponding to the request using a database table proxy session information table when the request does not identify the database silo.

17 . The system of claim 11 , wherein the database engine is further configured to manipulate data in the database silo in response to a request of the application without affecting data in the other database silos of the database table proxy.

18 . The system of claim 11 , wherein the database engine is further configured to define a database silo with a database silo name, whether data stored in the database silo is to be stored permanently, and whether the database silo can be shared between applications.

19 . The system of claim 11 , wherein the database engine is further configured to delete a content of the database silo after the application terminates when the database silo accessed indicates that the content is to not to be stored permanently.

20 . A non-transitory machine-readable storage medium storing instructions which, when executed by at least one processor, performs operations comprising:

forming a database table proxy as a logical database;

assigning one or more database silos to the database table proxy;

defining a default database silo from the one or more database silos for the database table proxy; and

accessing a database silo of the database table proxy corresponding to an application requesting access to the logical database at a database engine.
