(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.

(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 user-assigned number that identifies a direct access storage device (DASD) subsystem. This number is set by the service representative at the time of installation and is included in the vital product data (VPD).<br />(2) A number that uniquely identifies a logical subsystem (LSS) within a computer installation.
Industry:Software
(1) In Business Graphics Utility and the GDDM function, uniformly spaced horizontal and vertical lines on a chart.<br />(2) In AFP Utilities, horizontal and vertical lines printed on an AFP resource, such as an electronic overlay, to help in the design of the AFP resource.
Industry:Software
(1) In the GDDM function, a chart in which each value of the dependent variable corresponds to a range of values of the independent variable (represented by the width of the associated bar). For example, such a chart might display the number of people in various age ranges.<br />(2) In Performance Tools, a bar graph used in the performance advisor to display the variations over time of one type of data in a performance data collection.
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.
Industry:Software
(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.
Industry:Software
(1) A user-defined group of network resources within a single domain. Spans provide a level of security by allowing the system administrator to define (a) the resources to which an operator can issue commands, (b) the views of resources that an operator can display, and (c) the resources in a view that an operator is allowed to see (an operator might not be authorized to see all the resources in a particular view).<br />(2) An attribute of a policy that defines the range of influence of a policy in a policy hierarchy. For example, the span attribute indicates whether a policy in a policy hierarchy is inherited only by its immediate child nodes or by its immediate child nodes and all their descendents.
Industry:Software
(1) In Business Graphics Utility, a collection of values that identify the comparisons in a chart. For example, the relative size of the slices in a pie chart or the relative height of the bars in a bar chart. See also data value.<br />(2) In the GDDM function, a collection of data values displayed, for example, as a pie chart or as the plotted points on a line of a line chart. More than one data group may be displayed on a chart.
