Abstract

Embodiments of methods and systems consistent with the present invention allow for updating tenants in a hosted provider-tenant system by analyzing data structures associated with a particular tenant to determine a delta between the data structures associated with the particular tenant and new or modified data structures at the provider. Data structures may thus be created or updated at the provider and then compared to existing data structures stored in association with one or more tenants in the system. In this way, updates may be easily determined and imported to multiple tenants in the provider-tenant system.

Claims

1. A method of updating a first data structure related to a first tenant of a plurality of tenants in a provider-tenant system where a provider communicates with the plurality of tenants over a network, comprising:

selecting the first data structure based on an update notification;

comparing the first data structure to a second data structure related to a provider;

determining an update component based on the comparison; and

importing the update component to the first tenant.

2. The method of claim 1, further comprising:

sending the update component to the plurality of tenants.

3. The method of claim 1, wherein determining the update component comprises:

determining a difference between the first data structure related to the tenant and the second data structure.

4. The method of claim 1, further comprising:

creating the second data structure at the provider, wherein the second data structure is created based on a request by the first tenant.

5. The method of claim 1, wherein comparing comprises:

comparing the content of the first data structure to the content of the second data structure.

6. The method of claim 1, wherein comparing comprises:

determining a difference between a database schema related to the first data structure and a database schema related to the second data structure.

7. The method of claim 1, wherein selecting the first tenant comprises:

selecting the first tenant based on a business application running at the first tenant.

8. A method of updating a first business object of a first tenant, comprising:

selecting the first tenant from a plurality of tenants in a provider-tenant system;

selecting the first business object at the first tenant;

comparing the first business object of the first tenant to a second business object from the provider; and

determining an update to send to the first tenant based on the comparison.

9. The method of claim 8, wherein determining an update comprises:

determining a difference between the first business object and the second business object.

10. The method of claim 8, further comprising:

importing the update into a database of the first tenant.

11. The method of claim 8, further comprising:

sending the update to the plurality of tenants.

12. The method of claim 8, wherein comparing comprises:

comparing the content of the first business object to the content of the second business object.

13. The method of claim 8, wherein comparing comprises:

determining a difference between a database schema related to the first business object and a database schema related to the second business object.

14. The method of claim 8, wherein selecting the first tenant comprises:

selecting the first tenant based on a business application running at the first tenant.

15. A system for updating a first business object of a first tenant, comprising:

means for selecting the first tenant from a plurality of tenants in a provider-tenant system;

means for selecting the first business object at the first tenant;

means for comparing the first business object of the first tenant to a second business object from the provider; and

means for determining an update to send to the first tenant based on the comparison.

16. The system of claim 15, wherein the means for determining an update comprises:

means for determining a difference between the first business object and the second business object.

17. The system of claim 15, further comprising:

means for importing the update into a database of the tenant.

18. The system of claim 15, further comprising:

means for sending the update to the plurality of tenants.

19. The system of claim 15, wherein comparing comprises:

means for comparing the content of the first business object to the content of the second business object.

20. The system of claim 15, wherein comparing comprises:

means for determining a difference between the database schema related to the business object and the database schema related to the second business object.
