2. Drag and drop the relevant data items to create a relationship.
3. Specify the cardinality (one-to-one, one-to-many) and relationship type (inner join, outer join).
4. Validate the relationships to ensure data integrity.
Creating Calculated Fields
Calculated fields allow users to perform computations on data items. Here’s how to create them:
1. Right-click on the "Data Items" section and select "New Data Item."
2. Enter a name for the calculated field.
3. Use the expression editor to define the calculation using existing data items.
4. Validate the expression to ensure accuracy.
Testing and Publishing the Model
Once the data model is complete, it’s essential to test it before publishing.
Testing the Model
1. Click on the "Test" option in the toolbar.
2. Run queries to ensure that the data model returns the expected results.
3. Debug any issues that arise during testing.
Publishing the Model
To make the model available for reporting, follow these steps:
1. Right-click on the project name in the project tree.
2. Select "Publish" from the context menu.
