Abstract
Extensions to a database system provide linkage between data in the database system and files in a system for filing data which is external to the database system ('the filing system'). The linkage includes an external file reference (efr) data type which is defined in the database system for reference to files that are stored in the filing system. When entries are made in the database system that include efr data-type references to files in the filing system, control information is provided by the database system to the filing system. The control information causes the filing system to control processing of referenced files according to referential constraints established in the database system.
