| ### Backing Store Databases DCE provides a backing store library for the convenience of programmers who are writing DCE servers. A backing store is a persistent database or persistent object store from which typed data can be stored and retrieved by a key. Designed to satisfy the needs of programmers writing servers that deal with ACLs, this facility can be used to store any data Interface Definition Language (IDL) can describe that needs to persist between invocations of applications. The backing store routines can be used in servers, in clients, or in standalone programs that do not involve remote procedure calls (RPC). These cross-component facilities are described in detail in the OSF DCE Application Development Guide - Core Components. ##
