Why multitenancy:
Following the widespread adoption of cloud computing and in turn SaaS applications, multitenancy architecture has become very attractive since it offers multiple benefits compared to single tenant models. One of the main reasons that SaaS has gained ground in the application development industry is the fact that it is offering an architecture that helps in adopting a cost-cutting methodology. However, SaaS applications can only reap these benefits if they are opting for the multi-tenant architecture.

SaaS multi-tenant database design using petranna.db service (watch our video)
  1. the architect of the subscribed ISV alters the existing database schema to a multitenant aware.
  2. the architect configures the appropriate data adapters to consume the transformed database schema.
  1. the preconfigured data adapters transform the SQL statements, by combining them with tenant metadata, which results in a multi-tenant centric dataset or operation.
  1. petranna.db registers tenant identity.
  2. petranna.db applies multi-tenant centric changes on logical, security and physical database schema.
  1. ISV administrator manages & operates a multi-tenant database.
  2. tenant administrator manages & operates conseptual tenant database.
