APPLICATION SOFTWARE NOTES

READ THOSE NOTES AND MAKE A SUMMARY

APPLICATION SOFTWARE

These are programs designed to solve specific problems of the user. Application software is designed to perform the practical problems experienced in life.

Application software includes most of the types of programs we use every day to get our computerized work done.

Application programs are widely used in our society for entering and editing text (word processing), for entering and manipulating numerical data (spread sheets and other business programs), and for record keeping (database management programs). These types of programs are sometimes referred to as general purpose applications.

 

Classification of computer application software

 

  • Off-shelf and Bespoke (custom-made) software
  • Tailor made application software.
  • Shareware
  • freeware
  • Open source software
  • public domain software
  • Web based software
  • copyrighted software
  • Special purpose and general purpose software

 

 

  1. Off-shelf application software

These are already made programs bought ‘off-the shelves’ from a software shop or vendor.

It can also be defined as software that is ready-made and available to lots of people. You usually pay a license fee to use it

Off- shelf application software can further be divided into Horizontal market applications (common applications you can find on every office computer) and vertical market applications also known as specialized application programs.

Horizontal market software

These are software tools that are useful to almost any one in any job. These are programs you can find on almost every computer in every office. They include;

  • Spreadsheets used for organization and analysis of data in tabular form.
  • Word-processors used to produce text documents that are professionally laid out.
  • Presentation software used for creating presentations to show to customers or staff
  • Databases used for keeping customer records, sales records, appointments system
  • Desktop publishing packages used for creating leaflets, posters, business cards
  • Graphics packages for manipulating images that can be used at home, school or a business
  • Web design application used for creating personal or business web sites
  • Communication software among others.

 

Vertical market (specialized applications)

It consists of programs developed for a specific industry. Examples include Computer Aided Designs (CAD), Bakery recipes, Bridge analysis, airline ticketing, airplane wing structure, robots swivel control, electronic testing etc.

Advantages Off-shelf application

  1. It is relatively cheap, especially when compared to custom written software
  2. It is easily available from most computer shops
  3. It will have been thoroughly tested so there won’t be any serious problems or bugs
  4. There will be lots of user support i.e. books, user guides, online help and discussion forums on the Internet
  5. Lower training costs.If it is a commonly used package, users and I.T. staff may already be familiar with it, saving on learning time and training costs. Or, there may be pre-existing training materials and courses that you can leverage.
  6. More functionality.Off-the-shelf software often has more functionality, because the developers try to meet the requirements of as many users as possible. (There may even be functionality you didn’t realize you need!)
  7. The vendor will continue to develop the software, so you will likely get upgrades for free or at a reduced cost, whereas in bespoke software you don’t get anything new unless you pay for it to be built.

 

Disadvantages off-shelf:

 

  1. You may have to compromise on your requirements – it is unlikely you will find ready-made software that does everything you need it to, exactly how you want it to.
  2. May be overly complicated. The software may include functionality that you don’t need, as it is trying to meet the different requirements of a number of users. This can make it more difficult to learn and use.
  3. You are not in control. The vendor’s plans for the future may not always fit with your own. As a single customer amongst many, you may not be able to get the features you want implemented.

 

  1. Bespoke (custom-made) software/Tailor made application software.

Bespoke software is written especially for you, to meet your specific business requirements.

If very specialized software is needed, a company may decide to write or order its own software.

This software is called custom software.

This software is developed by computer specialists or programmers. Examples may include; admission software at IUIU, loan portfolio software for Cairo bank, programming in D-base dealing in hotel operations etc.

Advantages of bespoke (custom-made) software

  1. Tailored to you. The software is developed and built to meet your specific requirements, ensuring that you get software that works exactly how you need it to and delivers the results you want.
  2. More flexible. A bespoke system can evolve over time to match your changing requirements.
  3. No per-user fees. If you own the software, you won’t have to extra per-user fees as your business grows.
  4. Not tied in. You own the intellectual property, so you are not tied to a specific vendor that could potentially disappear at any time.
  5. Competitive advantage. As your competitors won’t have the same software, it could give you a competitive edge. An effective software package can make a company work more efficiently, improve their performance and have a positive impact on customer satisfaction levels.

The disadvantages are:

  1. Higher initial costs. It will cost more at the beginning, as you have to pay the development costs.
  2. Takes longer.Depending on the size and complexity of the software, it may take months or even years to develop.
