This symbol represents a document or report.

This rhombus represents data used as inputs/outputs
to/from a process.

A next step is to code the program in a particular programming language. The choice of the lan-
guage will depend on the programming paradigm and the platform adopted (such as hardware,
operating system, or network).

Once the source code of the program has been written, it will be given to a translator to translate it
to machine language (0s and 1s) so that it can be executed and solve the business problem.

During application development, it is important that every program is intensively tested to avoid any
errors. Often, in programming, errors are called bugs . Various types of errors exist and an entire
chapter is devoted to this topic. Programming tools frequently have debugging facilities built in to
