(1) In REXX, a token that represents the continuation character, a separator of arguments in an argument list, or a separator in a parsing template.<br />(2) A unique pattern (either binary 1100000 or binary 0011111) used in 8B/10B encoding to specify character alignment within a data stream. See also K28.5.
Industry:Software
(1) A technology that compresses and decompresses data for the purpose of reducing the bandwidth required to send streaming data.<br />(2) Pertaining to adapters that compress and decompress video files.

(1) In a relational database, a field defined for a given record or row.<br />(2) The vertical component of a database table. A column has a name and a particular data type (for example, character, decimal, or integer).<br />(3) A character position within a print line or on a display. The positions are numbered consecutively from 1, starting at the leftmost character position and extending to the rightmost position.<br />(4) A vertical arrangement of characters or other expressions. Columns are positioned side by side on a page or display. See also row.<br />(5) A subdivision of a band, such as baseline or actual.
Industry:Software
(1) In SQL replication, the content of a replication source-table column before it is updated by a transaction. The content is recorded in a change data (CD) table or in a database log or journal. See also after-image, before-value.<br />(2) The contents of a record in a physical file before the data is changed by a write, an update, or a delete operation.<br />(3) A record of the contents of a data element before it is changed. Before images are used to backout incomplete or incorrect changes in the event of a failure.
Industry:Software
(1) A storage area used by a programme to hold control information.<br />(2) In CICS, a storage area used to hold dynamic data during the execution of control programmes and application programs. See also control area, control table.
Industry:Software
(1) Data that is exported from one procedure and imported into another procedure. See also internal data.<br />(2) In COBOL, the data described in a programme as external data items and external file connectors.<br />(3) Data obtained from a channel (for example, external credits pending).<br />(4) Data that persists over the lifetime of an enclave and maintains last-used values whenever a routine within the enclave is reentered.
Industry:Software
(1) In REXX, a variable set automatically by the language processor. Special variables are RC, RESULT, and SIGL.<br />(2) A variable that is similar to a local or global variable, except that it is predefined in Data Interchange Services. Special variables are created during translation at the start of a document and cannot be created or maintained by the user.
Industry:Software
(1) A temporary object that contains the description of the format of a printed or displayed report, which was built without explicitly specifying a form to be applied against it.<br />(2) A form that is created when a query is run. The default form is not created if a saved form is run with the query.

(1) In a relational database, a key that uniquely identifies one row of a database table. See also constraint, unique key, foreign key.<br />(2) An object that uniquely identifies an entity bean of a particular type.<br />(3) In each record of a VSAM KSDS, an identifying field. The key of each record is a field in a predefined position within the record. Each key must be unique in the data set.<br />(4) In a federated system, a unique key that is part of the definition of a nickname and that the optimizer uses to improve query performance. This key is not validated when operations such as insert and update are performed.
Industry:Software
(1) In SQL replication, the process by which a target table is loaded with data from its source table. A full refresh replaces all data in a target table. See also change-capture replication.<br />(2) In Q replication, the process in which all of the data that matches the search conditions for a Q subscription for a replication source table is copied to a target table. A full refresh replaces all data in a target table.
