Application software :
Application software Application software, also known as
applications or apps, is computer software designed to help the
user to perform singular or multiple related specific tasks.
Examples include Enterprise software, Accounting software,
Office suites, Graphics software and media players. Application
software is contrasted with system software and middleware,
which manage and integrate a computer's capabilities, but
typically do not directly apply them in the performance of tasks
that benefit the user. A simple, if imperfect analogy in the world
of hardware would be the relationship of an electric light bulb
(an application) to an electric power generation plant (a system).
The power plant merely generates electricity, not itself of any
real use until harnessed to an application like the electric light
that performs a service that benefits the user.
Application software classification :
Application software classification An application suite consists of
multiple applications bundled together. They usually have related
functions, features and user interfaces, and may be able to interact
with each other, e.g. open each other's files. Business applications
often come in suites, e.g. Microsoft Office, OpenOffice.org, and I
Work, which bundle together a word processor, a spreadsheet, etc.;
but suites exist for other purposes, e.g. graphics or music. Enterprise
software addresses the needs of organization processes and data flow,
often in a large distributed environment. (Examples include
Financial, Customer Relationship Management, and Supply Chain
Management). Note that Departmental Software is a sub-type of
Enterprise Software with a focus on smaller organizations or groups
within a large organization. (Examples include Travel Expense
Management, and IT Helpdesk) Enterprise infrastructure software
provides common capabilities needed to support enterprise software
systems. (Examples include Databases, Email servers, and Network
and Security Management) Information worker software addresses
the needs of individuals to create and manage information, often for
individual projects within a department, in contrast to enterprise
management. Examples include time management, resource
Application Software:
Application Software includes
programs that do real work for
user.
Example:
Payroll systems, Inventory Control, Manage
student database, Word Processor,
Spreadsheet and Database Management
System etc.,
Application Software:
Word Processors:
Word processing is a tool that helps user in
creating, editing, and printing documents. Word
processors will normally have the following
capabilities built into them:
Spell checking
Standard layouts for normal documents
Have some characters appear in bold
print, italics, or underlined
Center lines, make text line up on the left
side of the paper, or the right side of the
paper
Save the document so it can be used
again
print the document.
Application Software
Spreadsheets: The spreadsheet packages
are designed to use numbers and formulas to do
calculations with ease. Examples of spreadsheets
include:
Budgets
Payrolls
Grade Calculations
Address Lists
The most commonly used spreadsheet programs
are Microsoft Excel and Lotus 123.
Application Software
Graphic Presentations: The
presentation programs can make giving
presentations and using overheads easier. Other
uses include:
Slide Shows
Repeating Computer Presentations on a
computer monitor
Using Sound and animation in slide shows
The most recognized graphic presentation
programs are Microsoft PowerPoint and Harvard
Graphics.
Application Software
Database Management System (DBMS):
A DBMS is a software tool that allows multiple
users to store, access, and process data into
useful information.
Database programs are designed for these types
of applications:
Membership lists
Student lists
Grade reports
Instructor schedules
All of these have to be maintained so you can
find what you need quickly and accurately.
Example: Microsoft Access, D BASE, Oracle.

Within application development
Written within an existing software environment
Examples: Spreadsheets, Database
applications
Turn key systems
Little customization – dependent on the vendor
“Turn it on and run it”
