We need to release V1 of our product. To do that we need to document certain things. Lets start by the flowchart process of current schema.

1. User Management Starter Schema.
2. Properties Schema.
3. Tenants and Profiles Schema.
4. Review and Message Table Schema ( if only necessary since there is nothing done here atm )
