Abstract

Embodiments of the present invention provide a metadata-driven software architecture that enables multi-tenant application development. Specifically, an application development architecture is provided including a data table that stores the application-accessible data that maps to all custom objects and their fields, as defined by metadata in objects and fields. Forms, reports, work flows, user access privileges, tenant-specific customizations and business logic, and definitions of underlying data tables and indexes exist as metadata. Application components are generated at runtime using the metadata.

Claims

1. A computer-implemented method for providing a metadata-driven software architecture that enables multi-tenant application development, comprising:

referencing a first metadata associated with an object;

referencing a second metadata associated with a field; and

storing an application-accessible data associated with a tenant, wherein the application-accessible data is defined by at least one of the first metadata or the second metadata.

2. The computer-implemented method of claim 1, wherein the application-accessible data is stored in a data table.

3. The computer-implemented method of claim 1, wherein the first metadata is stored in an object metadata table.

4. The computer-implemented method of claim 1, wherein the second metadata is stored in a field metadata table.

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

referencing at least one of a primary key metadata associated with a primary key field or a second key metadata associated with a second key field; and

storing the application-accessible data, wherein the application-accessible data is defined by at least one of the first metadata, the second metadata, the primary key metadata, or the second key metadata.

6. The computer-implemented method of claim 1, further comprising creating a tenant application using the application-accessible data.

7. The computer-implemented method of claim 6, wherein the tenant application is an on-demand database service application.

8. A system for providing a metadata-driven software architecture that enables multitenant application development, comprising:

a memory medium comprising instructions;

a bus coupled to the memory medium; and

a processor coupled to the bus that when executing the instructions causes the system to;

reference a first metadata associated with an object;

reference a second metadata associated with a field; and

store an application-accessible data associated with a tenant, wherein the application-accessible data is defined by at least one of the first metadata or the second metadata.

9. The system of claim 8, further comprising a data table configured to store the application-accessible data.

10. The system of claim 8, wherein the first metadata is stored in an object metadata table.

11. The system of claim 8, wherein the second metadata is stored in a field metadata table.

12. The system of claim 8 being further caused to reference at least one of a primary key metadata associated with a primary key field or a second key metadata associated with a second key field and store the application-accessible data, wherein the application-accessible data is defined by at least one of the first metadata, the second metadata, the primary key metadata, or the second key metadata.

13. The system of claim 8 being further caused to create a tenant application using the application-accessible data.

14. The system of claim 13, wherein the tenant application is an on-demand database service application.

15. A computer program product for providing an on-demand database service application composer, the computer program product comprising a computer readable storage media, and program instructions stored on the computer readable storage media, to:

reference a first metadata associated with an object;

reference a second metadata associated with a field; and

store an application-accessible data associated with a tenant, wherein the application-accessible data is defined by at least one of the first metadata or the second metadata.

16. The computer program product of claim 15, the computer readable storage media further comprising instructions to store the application-accessible data in a data table.

17. The computer program product of claim 15, wherein the first metadata is stored in an object metadata table and the second metadata is stored in a field metadata table.

18. The computer program product of claim 15, the computer readable storage media further comprising instructions to reference at least one of a primary key metadata associated with a primary key field or a second key metadata associated with a second key field and store the application-accessible data, wherein the application-accessible data is defined by at least one of the first metadata, the second metadata, the primary key metadata, or the second key metadata.

19. The computer program product of claim 15, the computer readable storage media further comprising instructions to create a tenant application using the application-accessible data.

20. The computer program product of claim 19, wherein the tenant application is an on-demand database service application.
