# GSA data
This chapter describes the different types of data that can be used to describe the model. The data is organised in modules and displayed for input and editing in a number of dialogs and tables. It is also possible to input and edit the data graphically (see Sculpting in the Working with the program section).
All dialogs and tables can be accessed from the Model > Data modules pull down menu, or from the Data explorer. Most tables have wizards which can be accessed from the Wizard button on the Data options toolbar, the Wizard option on the table context menu or Ctrl+W.
