Aspect-oriented software development (AOSD) is a new approach to software development that addresses limitations inherent in other approaches, including object-oriented programming. AOSD aims to address crosscutting concerns by providing means for systematic identification, separation, representation and composition. Crosscutting concerns are encapsulated in separate modules, known as aspects, so that localization can be promoted. This results in better support for modularization hence reducing development, maintenance and evolution costs.[Source: Early Aspects]
- Aspect Ratio
In computer graphics, the relative horizontal and vertical sizes. For example, if a graphic has an aspect ratio of 2:1, it means that the width is twice as large as the height. When resizing graphics, it is important to maintain the aspect ratio to avoid stretching the graphic out of proportion. The term is also […]
Aspects in aspect-oriented programming (AOP) package advice and pointcuts into functional units in much the same way that object-oriented programming uses classes to package fields and methods.
- aspherical surface
A lens surface with more than one radius of curvature (i.e., the surface does not form part of a sphere). The aspherical elements of a lens help compensate for many lens aberrations common in simpler lens designs. Aspherical elements are particularly important for wide-angle lenses, since they are prone to distortion. See “A Quick Guide […]
A program that translates programs from assembly language to machine language.
All of the files that comprise an application, including the resource, security management, versioning, sharing and deployment information. An assembly may appear as a single DLL or EXE file, or as multiple files, and is roughly the equivalent of a COM module.
