 Presentation Tools: A presentation tool is a general purpose application software
that lets us create presentations on any topic. We can not only create a presentation

audio-video files can be added to the presentations. Popular examples of presentation
tools software are Impress (open office) and Microsoft PowerPoint.
 Spreadsheet Packages: Spreadsheet is a general purpose application software that
allows us to create and store data in tabular form. Both text and numerical values
can be entered in those tables, known as spreadsheets. We can not only create a
document and add data to it but also create different types of charts and graphs
based upon the numerical data stored in that page. All common mathematical
and statistical formulae can be used on the numeric data. Popular examples of
spreadsheet software are Calc (Open Office) and Microsoft Excel.

SQL Server, ODBC, etc. Popular examples of Database Management System are Base

 Integrated Development Environment (IDE): To create large application programs,
a developer needs to use the requisite tools. The developer needs an environment
(the programming environment) where they can use the tools to create programs
for applications. Various application software provide a programming environment
to develop applications. Such a programming environment is commonly known as
IDE. Thus, an IDE consists of various development tools required for creating or
designing applications. NetBeans IDE is the most popular example of IDE.
