About this task
To create a new data model, proceed as follows:
In the MDM Repository tree view, right-click
Data Model and select New from
the contextual menu.
A dialog box pops up.
- Enter a name for the new model. Make sure that the name contains valid characters and does not already exist.
Keep the Create the corresponding Data Container at the same
time check box selected, so that the corresponding data
container with the same name will be created.
If needed, you can clear this check box and create its corresponding data container later.Warning: A data container and its corresponding data model must have the same name.
Click OK to validate your changes and close the dialog
The newly created data model and its corresponding data container will be shown in the MDM Repository tree view.
Double-click the data model to open a default editor in the Studio workspace
where you can set up the parameters for the new data model.
If needed, click the ... button next to
Description to open a dialog box where you can add
multilingual descriptions to the new data model.
Note that after a data model being created, the description of the data model cannot be modified together with the schema of the data model. If you want to update the description of the data model, update and redeploy it separately.Once you define the multilingual descriptions for the data model, authorized users can hover over the data model or its corresponding data container in the Domain Configuration area to view in a tooltip the localized description corresponding to the selected locale when they access Talend MDM Web UI.
You can define your business entities, attributes, annotations, etc. in the upper part of the editor; while the lower part will display the properties of any of the elements you select in the editor.
The editor also enables you to switch to the XML schema source by clicking the Schema Source tab. After clicking the Schema Source tab at the bottom of the editor, you can create the data model directly in the schema source, that is, an XML schema document.
Additionally, the editor enables you to switch to a graphical view of the data model by clicking the Design tab. You can design a data model from scratch using the graphical designer.
