For further information about data containers, see Data Containers.
Data models contain entities which are master data objects (or business entities) such as a Person, a Product, an Organization, etc. Each entity is defined by its attributes which are the entity characteristics, for example, for the Person entity, the attributes could be name, date of birth, address, etc.
Entity names must be unique, both within a Data Model and across multiple Data Models deployed to the same MDM Server.
When creating a data model from Talend Studio, you compartmentalize records and data to create the most efficient data model possible. In addition, you can define the attributes and relationships of entities mastered by the MDM Hub.
You can also import/export, edit, copy/paste and delete data models.
