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.

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.
