When you create a new custom app, FileMaker Pro Advanced opens in Browse mode and displays the Manage Database dialog box, where you define fields. Several default fields may already be defined (see Defining database tables). You create each field name and choose its field type. Then you can select options that determine how the field interprets, enters, calculates, stores, and displays data.
Note You can also use the Fields tab in Layout mode to define and change fields. See Defining and changing fields in the Fields tab.
