# Big Object Definition Details

When you create a custom big object, several required fields define how you can access the big object.

The big object definition details page displays information about the big object’s fields and index.

              <p>A unique name used to refer to the object when using the API. In managed
                packages, this name prevents naming conflicts with package installations. Use
                only alphanumeric characters and underscores. The name must begin with a letter
                and have no spaces. It cannot end with an underscore nor have two consecutive
                underscores.</p>
              <p style="margin-bottom:0;">In the API, the names of custom big objects have a suffix of
                two underscores immediately followed by a lowercase “b” (__b). For example,
                a big object named “HistoricalInventoryLevels” is seen as
                HistoricalInventoryLevels__b in that organization's WSDL.</p>
