Introduction to the MDM demo project
Talend provides you with an MDM demo project that you can import into Talend Studio. The MDM demo project encompasses the realization of some basic MDM features, which help you get started with Talend MDM and discover how to setup and configure the features of Talend MDM via meaningful samples.
For how to import the MDM demo project into Talend Studio, see Importing a demo project.
After launching Talend Studio and importing the MDM demo project into Talend Studio, you will find the following sample items in the MDM repository.

Each view specifies which elements, in one or multiple entities, are viewable or searchable.
