Multienterprise and Single Enterprise Design Considerations
You must decide early in the design process whether to use TIBCO MDM with multi-enterprise or single-enterprise tenancy.
You should take several factors into consideration when making this decision. For example, multienterprise tenancy is a good design choice if you use all the enterprises similarly and you want a single point of operational control.
Single enterprise tenancy is a good choice if you want physically separated enterprises to which you can separately assign the required resources. This choice, however, comes with overhead costs: the total resources needed to maintain multiple single enterprise tenancies is significantly higher than those required for a multienterprise tenancy.
Before deciding on a multienterprise or single enterprise tenancy, consider whether your configuration is likely to change. Separating an enterprise from a multienterprise tenancy to create a single enterprise tenancy is possible. However, doing so is tedious and requires several manual steps and consultation with TIBCO Support. Merging an enterprise from a single enterprise tenancy to a multienterprise tenancy is relatively easier but does require some manual steps. These steps may include recreating the enterprise in multienterprise tenancy and importing the data and meta-data into the new environment).
In multienterprise tenancies, using a single data store you can use a single set of reporting tools for data analysis and aggregation across enterprises.
You should also consider performance characteristics. In most cases, TIBCO recommends a multienterprise tenancy if the enterprises are small (fewer than 50 million records). Enterprises with records exceeding 300 million records should in most cases be configured as single enterprise tenancies.
