## Opening a New Data Model
In this article, we’ll talk about how you can access the built-in data modeler in Astera Data Stack.
You can open a data model in Astera Data Stack through the main menu, the main toolbar, and also through Project Explorer.
Let’s explore each of these options one by one.
You can also open a data model directly using a Windows shortcut.
### Using the Main Menu
On the main menu bar, go to *File > New > Data Model*.
### Using the Main Toolbar
There is an option to open a data model directly from the main toolbar.
### Using Project Explorer
When you create a *Data Warehousing* project, it will appear in the *Project Explorer*.
To open a new data model from the *Project Explorer*, right click on *Data Models* and select *Add New Data Model*.
Another way to open a data model through the Project Explorer is by right-clicking on *Data Models* and selecting *Add New Item*. There, you would find an option by the name of *DataModel*.
Select *DataModel*, *name* your data model and click *Add*.
A new data model will be added to your project folder and will open on the designer.
This concludes our discussion on the various ways of opening a data model.
