Glossary

access mode

the level of access that a user has to an item store. The possible access modes are

read, write, and update.

ActiveX

a technology developed by Microsoft that is used to add interactivity to web pages.

ActiveX control

a type of web application that is developed specifically for the Windows operating

environment. ActiveX controls can provide web users with interactive capabilities.

after-note

in ODS, a note that is displayed after an output object each time the output object is

displayed. The text is assigned to an output object by the procedure that produced the

object.

aggregate storage location

a location in an operating system that can contain a group of distinct files. Depending

on the operating system, the location could be a directory, folder, or partitioned data

set.

aliasing

a visual effect in computer-generated images that produces several types of rendering

problems, such as jagged edges along straight lines or polygon boundaries. Aliasing

can occur when you try to render an object smaller than pixel size or a very narrow

object. In a complex scene, fine details are sometimes lost or distorted beyond

recognition due to aliasing.

annotation

a label, marker, or note that is not obtained from the data but is placed on a graph

independently. Such annotations might or might not be linked to data values in the

plot.

anti-aliasing

a rendering technique for improving the appearance of text and curved lines in a

graph by blurring the jagged edges normally present. The degree of improvement is

relative to the nature of the graphical content (for example, vertical and horizontal

lines do not benefit from anti-aliasing). Extra processing is required to perform anti-

aliasing.
