Abstract: The present invention is directed to storing and manipulating data and coordinating communications for a plurality of tenants within a single system. The system maintains a core schema containing common core objects and a plurality of pre-developed industry-specific schema templates. When a new tenant is added to the system, one of the industry-specific schema templates corresponding to the tenant's industry is cloned to generate a tenant schema for the new tenant. Once the tenant schema for the new tenant has been populated with data, communications to clients of that tenant may be generated according to universal communication rules and industry-specific communication rules applicable to that tenant, and optionally according to tenant-specific communication rules.
