Creating a data model
Creating a new data model
To create a new data model, click the Create button in the pop-up, and follow through the wizard.
Selecting a data model type
If you are a user with the 'Administrator' role, you must choose the type of data model you are creating, semantic or relational, in the first step of the data model creation wizard.
Semantic models
Semantic models enable the full use of data management features, such as life cycle management using dataspaces, provided by TIBCO EBX®. This is the default type of data model.
Relational models
Relational models are used when the tables created from a data model will eventually be mapped to a relational database management system (RDBMS). The primary benefit of using a relational model is the ability to query the tables created from the data model using external SQL requests. However, employing a relational model results in the loss of functionalities in EBX® such as inheritance, multi-valued fields, and the advanced life cycle management provided by dataspaces.
Note
A relational data model can only be used by a single dataset, and the dataspace containing the dataset must also be declared as being relational.
