Abstract.
 
Yellowfin is the only BI product that has been designed from the ground up to support SAAS deployments either as a standalone application or embedded into a SAAS solution. You can deploy Yellowing in traditional hosted environments or in the Cloud supporting either multi database or multi-tenancy environments. At Yellowfin we understand the complexities of Multi-tenancy support. You have gone to a lot of trouble to build an application that partitions data based on your client id - well here is a BI tool that lets you continue to do the same.

Extract.

With Yellowfin you can:
1. Share common content across all your clients as well as allow clients to create their own unique reports; and
2. Partition a single data base by dynamically filtering data based on their client id; and
3. Dynamically swap database connections if you have a unique instance of database for each client whilst sharing common content

To support a SAAS environment Yellowfin features functionality called “Client Organizations” which allows multiple virtual instances of Yellowfin to reside within the same server instance. This allows content to be created and segregated from other organizations logging onto the same Yellowfin server.

Client Organization functionality operates on a two-tier basis. The top tier, known as the Default Organization, can have content that is shared between all Client Organizations.
Content created at the second-tier will not be visible to any other second-tier instances of Yellowfin.

Yellowfin's Client Organization functionality is managed completely by web services. Web services exist to create and delete Client Organizations from Yellowfin. Other web services allow for the management of users in regards to Client Organization access and logging the user into a particular Client Organization.
