Creation and management of multi-tenant application services

A computer-readable storage medium, having embodied thereon a program, the program being executable by a processor to perform a method for providing application services to multiple tenants, the method comprising:

• receiving at least one data model from a new tenant;
• creating a database specific to the new tenant, the database comprising one or more metadata tables;
• storing the data model received from the new tenant in the created database, wherein a plurality of databases are also stored, each database associated with a specified tenant;
• and
• providing an application service to the new tenant based on the data model received from the new tenant and stored in the created database.

A method for providing application services to multiple tenants, the method comprising:

• receiving at least one data model and requirement from a new tenant;
• creating a database specific to the new tenant, the database comprising one or more metadata tables stored in memory;
• storing the data model received from the new tenant in the created database, the database being further associated with a plurality of other tenants, wherein data specific to each tenant remains confidential from the plurality of other tenants;
• and
• providing an application service to the new tenant based on the data model received from the new tenant and stored in the created database.

A method for providing application services to multiple tenants, the method comprising:

• maintaining in memory a set of libraries, each library comprising resources for extending functionality of a service;
• organizing the set of libraries in memory, wherein the set of libraries is organized in a hierarchy comprising a plurality of tiers, wherein a first tier is accessible to a set of the plurality of tenants associated with the database and a second tier is accessible to a subset of the set, the second tier being downstream from the first tier;
• receiving an update concerning a library in the set of libraries;
• and
• updating a service functionality in the library in accordance with the received update. wherein the service functionality is updated for the set of the plurality of tenants having access to the library.
