a way of looking at (and controlling) organizational processes. Store Store components temporarily store information which is not required, desired, or ready for long-term storage or preservation. Even if the store component uses media suitable for long-term archiving, it is still separate from "preserve." Store components may be divided into three categories: Repositories: storage locations Library services: administration components for repositories Storage technologies Repositories ECM repositories may be combined. Types include: File systems: Used primarily for temporary storage, as input and output caches Content management systems: Storage and repository systems for content; may be a database or a specialized storage system Databases administer information, and can also store documents, content, or media. Data warehouses: Complex storage systems based on databases, which provide information from a variety of sources. They may be designed with global functions, such as documents or information. Library services Library services are ECM administrative components which handle access to information, taking in and storing information from the capture and manage components. They also manage the storage locations in dynamic storage, the store, and the long-term preserve archive. The storage location is determined by information characteristics and classification. The library service works with the manage components' database to provide search and retrieval. It manages online storage (direct access to data and documents), nearline storage (data and documents on a medium which can be accessed quickly, such as data on an optical disc in a storage system's racks but not inserted in a drive that can read it), and offline storage (data and documents on a medium which is not quickly available). If the document management system does not provide it, the library service must have version management to control the status of information and check-in/check-out for controlled information provision. It generates an audit trail, logs of information usage and editing. Storage technologies A variety of technologies can be used to store information, depending on the application and system environment: Magnetic online media: Hard disk drives (typically configured as RAID systems) may be locally attached, part of a storage area network, or mounted from another server (network-attached storage). Magnetic tape: Magnetic tape data storage, in the form of tape libraries, use robotics to provide nearline storage. Standalone tape drives may be used for backup. Digital optical media: In addition to compact disc and DVD optical media, storage systems may use magneto-optical drives; optical jukeboxes can be used for nearline
