General purpose packagesA general-purpose application package is a type of software that can perform many different related tasks.

This type of software is sometimes called generic software.

Database packages are used to store and retrieve information;

Spreadsheet packages are used for tasks that involve a lot of calculations or for the production of graphs and charts;

Word processing packages are used to produce text based documents such as

letters, reports and memos;

Common types of general purpose software

Integrated packagesThese combines many different types of application together in one single package. E.g word processing, spreadsheets, databases, graphics, presentation and communications.

Integrated packages are much cheaper than buying many different application packages but their different applications have a limited number of features compared with individual application packages.

Microsoft WORKS is an example of an integrated package.

Specialist application softwareSpecialist application software performs a single very specific type of task.

Examples include programs to work out payroll, calculate accounts, deal with stock control and handle appointments.

Tailor-made softwareTailor-made, or bespoke software specially developed for a particular company.

The main drawbacks of this approach:· High cost;· Time to develop;· Possible bugs.
