Abstract

Method(s) and system(s) for identifying an application behavior of a multi-tenant application for a tenant are described herein. The method includes determining whether a reference attribute of the multi-tenant application is encountered by the tenant. The reference attribute is an application attribute for which variations from a default behavior of the multi-tenant application are available. Based on the determining, it is ascertained whether a configuration template is defined for the tenant. Further, based on the ascertainment of the configuration template, the application behavior corresponding to the tenant is identified. The identified application behavior is provided to the multi-tenant application such that multi-tenant application exhibits the identified application behavior.

Claims

1. A method comprising:

receiving a request for access to a multi-tenant application from a tenant;

configuring application attributes of the multi-tenant application for the tenant, wherein each of the application attributes determines an application behavior of the multi-tenant application, wherein the configuring comprises, for each application attribute;

determining whether an application attribute is a reference attribute of the multi-tenant application, wherein the reference attribute corresponds to a common code of a varying application attribute that varies between tenants, the common code being external to a source code of the multi-tenant application, wherein the reference attribute is mapped to at least one differential attribute of the multi-tenant application in a metadata repository, wherein the at least one differential attribute is a variation of the application attribute over the reference attribute;

ascertaining, based on the determining, whether a configuration template is defined for the tenant, wherein the configuration template comprises the at least one differential attribute for a tenant group of which the tenant is a member; and

identifying the application behavior of the application attribute based on the ascertaining, wherein the application behavior is identified based at least on the reference attribute and the at least one differential attribute; and

providing the identified application behavior for each of the application attributes to the multi-tenant application such that the multi-tenant application exhibits the identified application behavior for the tenant.

2. The method as claimed in claim 1, further comprising:

determining at least one parent configuration template from which the configuration template is derived; and

wherein the application behavior is identified based at least in part on the at least one parent configuration template.

3. The method as claimed in claim 1, further comprising:

determining a locale attribute corresponding to the tenant; and

wherein the application behavior is identified based at least on the locale attribute.

4. The method as claimed in claim 1 further comprising determining a default value of the application attribute, when the reference attribute is not encountered.

5. The method as claimed in claim 1, wherein the reference attribute is at least one of a user interface, a processing step, a business rule, a workflow, an access control, an application data structure, a report, or an integration with other multi-tenant applications.

6. The method as claimed in claim 1, wherein the identified application behavior indicates at least one of default behavior or a variation from the default behavior.

7. The method as claimed in claim 1, wherein the configuration template is associated with the tenant group.

19. The method as claimed in claim 1, wherein the at least one differential attribute includes a default value of the application attribute corresponding to the reference attribute.

8. A multi-tenant system comprising:

a processor; and

a memory coupled to the processor, the memory comprising an attribute identification module configured to,

determine whether a reference attribute of a multi-tenant application is encountered while configuring the multi-tenant application for a tenant, wherein the reference attribute corresponds to a common code of a varying application attribute that varies between tenants, the common code being external to a source code of the multi-tenant application, wherein the reference attribute is mapped to at least one differential attribute of the multi-tenant application in a metadata repository, wherein the at least one differential attribute is a variation of the application attribute over the reference attribute, and wherein the application attribute is associated with an application behavior;

ascertain whether a configuration template is defined for the tenant, when the reference attribute is encountered, wherein the configuration template comprises the at least one differential attribute for a tenant group of which the tenant is a member; and

identify the application behavior of the application attribute based at least on the reference attribute and the at least one differential attribute.

9. The multi-tenant system as claimed in claim 8, wherein the attribute identification module is further configured to identify the application behavior based in part on the configuration template and the reference attribute, when the configuration template is defined for the tenant.

10. The multi-tenant system as claimed in claim 9, wherein the attribute identification module is configured to:

determine at least one parent configuration template from which the configuration template is derived; and

identify the application behavior based at least in part on the at least one parent configuration template.

11. The multi-tenant system as claimed in any of the claims 8 to 10, wherein the attribute identification module is further configured to:

determine a locale attribute corresponding to the tenant; and

identify the application behavior based at least on the locale attribute.

12. The multi-tenant system as claimed in claim 10, wherein the at least one parent configuration template is a base template.

13. The multi-tenant system as claimed in claim 8, wherein the multi-tenant system is associated with the metadata repository, and wherein the metadata repository includes metadata pertaining to tenants, to a base template, one or more configuration templates, inheritance of configuration templates, reference attributes, and application attributes associated with the multi-tenant application.

14. The multi-tenant system as claimed in claim 8 further comprising, a configuration module configured to create at least one of a base template for the multi-tenant application or one or more configuration templates for the multi-tenant application.

15. The multi-tenant system as claimed in claim 8, wherein the attribute identification module is configured to provide a default attribute value for the reference attribute, when no application behavior is identified.

20. The multi-tenant system as claimed in claim 8, wherein the at least one differential attribute includes a default value of the application attribute corresponding to the encountered reference attribute.

16. A non-transitory computer readable medium having computer executable instructions which when executed, implement a method comprising:

determining, for each application attribute of a multi-tenant application being configured for a tenant, whether an application attribute is a reference attribute of the multi-tenant application, wherein the reference attribute corresponds to a common code of a varying application attribute that varies between tenants, the common code being external to a source code of the multi-tenant application, wherein the reference attribute is mapped to at least one differential attribute of the multi-tenant application in a metadata repository, wherein the at least one differential attribute is a variation of the application attribute over the reference attribute, and wherein the application attribute is associated with an application behavior of the multi-tenant application;

ascertaining, based on the determining, whether a configuration template is defined for the tenant, wherein the configuration template comprises the at least one differential attribute for a tenant group of which the tenant is a member;

identifying the application behavior of the multi-tenant application for the tenant based on the ascertaining, wherein the application behavior is identified based at least on the reference attribute and the at least one differential attribute; and

providing the identified application behavior to the multi-tenant application such that the multi-tenant application exhibits the identified application behavior for the tenant.

17. The non-transitory computer readable medium as claimed in claim 16, wherein the method further comprises:

determining at least one parent configuration template from which the configuration template is derived; and

wherein the application behavior is identified based at least in part on the at least one parent configuration template.

18. The non-transitory computer readable medium as claimed in claim 16, wherein the method further comprises:

determining a locale attribute corresponding to the tenant; and

wherein the application behavior is identified based at least on the locale attribute.
