The [business model|PentahoDoc:00. Metadata Terminology#BusinessModel] is where the logical mapping of business objects to the physical tables and columns we just set up happens. The model is also the place where we define the relationships between our business tables, and organize the business view.

As mentioned before, a domain can have multiple business models.

h1. Creating a Business Model

To create your first business model:
# Right-click (or CTRL-click) the *Business Models* node in the Tree Navigator. Select *New Business Model...* option from the popup menu.
# The *Model Properties* dialog displays.
# At the top of the dialog, there is an ID text field, pre-populated with a value. We recommend you accept the pre-populated value as this value MUST be unique across all models that you define.
# To name your new model, enter a new value in the Name property text box on the right. !metadata_model_properties.png|align=center!
Click the *OK* button to close the dialog.

Your business model will show up in the Navigator Tree.  All business models by default are created with a place to hold business tables, relationships and a business view. These are the next items you will want to define.
* [PentahoDoc:04. Creating Business Tables and Columns]
* [PentahoDoc:05. Creating Relationships Between Business Tables]
* [06. Building a Business View]\\
