Terms used by software programmers and developers

Terms used by software programmers and developers

As a creator of an idea that will become a software application you will spend a lot of time talking with developers, programmers and coders. It is not unusual to listen to a conversation or read something they have written and be confused about the terms they use and what they mean. This glossary has been compiled to assist with understanding the landscape.

 

TERM DESCRIPTION
3-tier application A program that is organized into three major parts: the workstation or presentation interface; the business logic; and the database and related programming. Each of these is distributed to one or more separate places on a network.
agile software development Calls for keeping code simple, testing often, and delivering small, functional bits of the application as soon as they’re ready. The focus is to build a succession of parts, rather than delivering one large application at the end of the project.
Amdahl’s law Stipulates that, in a program with parallel processing, a relatively few instructions that have to be performed in sequence will have a limiting factor on program speedup such that adding more processors may not make the program run faster.
amelioration pattern A design pattern that describes how to go from a bad solution to a better one.
antipattern A frequently used, but largely ineffective solution to a problem. The term was originally used to refer to a design pattern gone wrong
API

(application programming interface)

A specific method prescribed by a computer operating system or by an application program by which a programmer writing an application program can make requests of the operating system or another application
application integration The process of bringing data or a function from one application program together with that of another application program. Where these programs already exist, the process is sometimes realized by using middleware
application program A program designed to perform a specific function directly for the user or, in some cases, for another application program.
aspect-oriented programming

(AOP)

An approach to programming that allows global properties of a program to determine how it is compiled into an executable program.
back end
