# Editing a semantic model

A semantic model organizes physical data into a multi-dimensional structure that has meaning to your business. Edit a semantic model to rename it, change its connection details or attributes, or to edit the elements inside model. You can also delete the model or the elements inside of it.

For instructions on editing a cube or its elements, see the following topics:  

* [Rename a semantic model](/pba/semantic-model-editor/editing-a-semantic-model/rename-a-semantic-model.md)

  You can change the name of a semantic model to a new, unique name.  
* [Edit data connection details in a semantic model](/pba/semantic-model-editor/editing-a-semantic-model/edit-data-connection-details-in-a-semantic-model.md)

  You can edit the data connection that connects the semantic model to a physical source of data by selecting a new connection from the list or entering details for a new connection. 
* [Edit semantic model attributes](/pba/semantic-model-editor/editing-a-semantic-model/edit-semantic-model-attributes.md)

  You can edit the default role, description, and caption for a semantic model.
* [Edit a cube](/pba/semantic-model-editor/editing-a-semantic-model/edit-a-cube.md)

  A cube contains aggregated data from a semantic model's physical connection. You can rename a cube and change its description, visibility, and availability. You can also edit elements in the cube that control the data that is aggregated and quantified in the cube.
* [Edit a shared dimension](/pba/semantic-model-editor/edit-a-shared-dimension.md)

  Edit a shared dimension, its hierarchies, and the levels of those hierarchies, to change the properties that describe the shared dimension and control its visibility and availability. Shared dimensions describe aggregated data in a cube so that the data can be grouped for analysis. 
* [Delete a semantic model](/pba/semantic-model-editor/delete-a-semantic-model.md)

  Delete a semantic model that you no longer need for analysis or reporting. 
* [Delete elements in a semantic model](/pba/semantic-model-editor/delete-elements-in-a-semantic-model.md)

  Delete elements from a semantic model that you no longer need.
