(1) A logical unit of storage in a database. In DB2 for z/OS, a table space is a page set and can contain one or more tables. In DB2 Database for Linux, UNIX, and Windows, a table space is a collection of containers, and the data, index, long field, and LOB portions of a table can be stored in the same table space or in separate table spaces. See also page set, container.<br />(2) A page set that is used to store the records in one or more DB2 for z/OS tables. See also segmented table space.<br />(3) A logical unit of storage in a database.
Industry:Software
(1) A logical view of the organization of data in a database.<br />(2) A description of the organization of data in a manner that reflects the information structure of an enterprise.<br />(3) A model defining the structure of business artifacts that are operated upon by business operations.

(1) A major CICS storage control block that contains areas and data required for the operation of CICS.<br />(2) In MVS, an area that contains system control programs and control blocks. The storage areas within the common area are the system queue area (SQA), the pageable link pack area (PLPA), the (optional) modified link pack area (MLPA), a pageable BLDL table, a copy of the prefixed storage area (PSA) (for multiprocessor systems only), and a common system area (CSA).
Industry:Software
(1) A means of grouping committable resource operations to allow either the processing of a group of committable resource changes as a single unit through the Commit command, or the removing of a group of committable resource changes as a single unit through the Rollback command.<br />(2) A way of grouping file operations that allows the processing of a group of database changes as a unit or the removal of a group of database changes as a unit. See also roll back.
Industry:Software
(1) A means of preventing uncommitted changes made by one application process from being perceived by another application process and for preventing one application process from updating data that is being accessed by another process. A lock ensures the integrity of data by preventing concurrent users from accessing inconsistent data.<br />(2) The process by which integrity of data is ensured by preventing more than one user from accessing or changing the same data or object at the same time.<br />(3) A mechanism with which a resource is restricted for use by the holder of the lock.<br />(4) A means of serializing a sequence of events or serializing access to data.<br />(5) To temporarily restrict resources to provide protection from concurrent users of the system.
Industry:Software
(1) A measure of memory or storage capacity that is 2 to the 50th power bytes or approximately a thousand terabytes.<br />(2) For disk storage capacity and communications volume, 1 000 000 000 000 000 bytes.
Industry:Software
(1) A measurement of the ability of a system to continue processing without failure. Shutting down an on-line system to process batch updates to the database reduces its availability to end users but has no bearing on the reliability of components required to deliver the online service.<br />(2) The ability of a system to continue to return data even if a component fails.
