The basic unit of data storage for the Force.com platform is the object. An object is similar to a table in a relational database - both entities are collections of fields, although a custom object has a range of custom fields with broader built-in functionality than a standard object.

Once you have defined a custom object, you can add custom fields to the object to specify the data you wish to store in the object.
For more information on the creating a custom object, including a description of all of the choices you will have in the creation process, please click on the Help for this page link in the upper right corner of the main Custom Object page.
