Setting up a data model

You can create one or multiple data models for any domain and store them in the MDM Hub.

A few steps are necessary to complete the creation of a data model:

1. Create business entities in the model.

2. Adding attributes in each of the created business entities.

3. Set annotations to entities or attributes regarding access control, display issues, role authorization, foreign key, etc.

You can also define reusable types for any data model. These reusable types are sets of attributes that can be used in one or more entities of the data model. Using reusable types is a way of factoring the data model and managing the impact of changes since any modification on a reusable type will have an impact on every entity that uses this type.

Once the data model is created, you can easily create Views over one or multiple business entities held in this data model. For example, you can right-click any of the entities held in this data model and automatically generate a default View for the selected entity.

A View allows a business user accessing Talend MDM Web UI to visualize specific records in this entity according to the defined criteria.

Moreover, an authorized user of Talend MDM Web UI can validate hub data against these data models.
