Abstract

In one embodiment, the present invention includes a computer-implemented method comprising storing data in an application using an application custom data type and application custom data structure. The data is stored in a database using the application custom data type and the application custom data structure. In one embodiment, a request is sent to access the data from the application to the database. The data is retrieved from the database in response to the request in the application custom data type and the application custom data structure. In one embodiment, the data is sent from the database to a shared memory in the application custom data type and the application custom data structure and the data is retrieved by the application from the shared memory in the application custom data type and the application custom data structure.

First claim

What is claimed is:

1. A computer-implemented method comprising:
storing data from an application operating on an application server in an application format defined by an application custom data type and an application custom data structure in an in-memory database operating on a database server, the database server further comprising a hard disk drive storing other data in a database format that is different from the application format, wherein the application server and the database server are virtual machines;
retrieving the data from the in-memory database in response to a request to access the data;
storing the data from the in-memory database in a shared memory;
accessing the data from the shared memory for use in the application;
receiving the application custom data structure in the in-memory database;
transforming the other data stored in the hard disk drive from the database format to the application format using the application custom data structure processed by an in-memory database engine;
sending the transformed other data from the database to the shared memory in the application format; and
further comprising causing the in-memory database engine to perform an operation on the transformed other data.

2. The method of claim 1 wherein the shared memory is accessible by both the application server virtual machine and the database server virtual machine.

3. The method of claim 1 wherein the operation comprises a SQL operation.

4. The method of claim 1 wherein the operation comprises a custom operation.

5. A computer-implemented method comprising:
receiving data from an application in an application format defined by an application custom data type and an application custom data structure;
storing the data from the application in an in-memory database in the application format on a database server, the database server further comprising a hard disk drive storing other data in a native database format different from the application format, wherein the data is stored, by the application, in an application memory using the application format, and wherein the data is stored in a database memory using the application format;
transforming the other data from the native database format to the application format using the application custom data structure processed by an in-memory database engine;
retrieving the data from the database in the application format;
sending the data in the application format for use in the application; and
further comprising causing the in-memory database engine to perform an operation on the transformed other data.

6. The method of claim 5 wherein the application is operable on a virtual application server and the database is operable a virtual database server.

7. The method of claim 5 further comprising sharing a memory accessible by both virtual application server and the virtual database server to transfer said data in the application format between the virtual application server and the virtual database server.

8. The method of claim 5 wherein the operation comprises a SQL operation.

9. A non-transitory computer readable storage medium embodying a computer program for performing a method, said method comprising:
storing data from an application operating on an application server in an application format defined by an application custom data type and an application custom data structure in an in-memory database operating on a database server, the database server further comprising a hard disk drive storing other data in a database format that is different from the application format, wherein the application server and the database server are virtual machines;
retrieving the data from the in-memory database in response to a request to access the data;
storing the data from the in-memory database in a shared memory;
accessing the data from the shared memory for use in the application;
receiving the application custom data structure in the in-memory database;
transforming the other data stored in the hard disk drive from the database format to the application format using the application custom data structure processed by an in-memory database engine;
sending the transformed other data from the database to the shared memory in the application format; and
wherein the method further comprises causing the in-memory database engine to perform an operation on the transformed other data.

10. The non-transitory computer readable storage medium of claim 9 wherein the shared memory is accessible by both the application server virtual machine and the database server virtual machine.

11. The non-transitory computer-readable storage medium of claim 9 wherein the operation comprises a SQL operation.
