How to configure a TYPOlight Data Container Array

Data Container Arrays (DCAs) are used to store table meta data. Each DCA describes a particular table in terms of its configuration, its relations to other tables and its fields. The TYPOlight core engine determines by this meta data how to list records, how to render back end forms and how to save data. The DCA files of all active module are loaded one after the other (starting with backend and frontend and then in alphabetical order), so that every module can override the existing configuration. The system/config/dcaconfig.php file is included at the end.
