 What is a tar pit ?  From its original meaning, a tar pit is an accumulation that has acted as a natural trap into which animals have fallen and sunk and their bones have preserved.

 It basically refers to the factors that can cause a program not to work and getting trapped with bugs preventing it from doing the work that it was created for.

 Cause: Many large computer systems programs over the past decade have been into such a tar pit.

 Therefore, we must understand the cause of a tar pit if we are to solve it.

 A programming product in this sense is a program that can be tested, repaired and extended by anybody

 In order to become an efficiently good programming product, a program must be written in a generalized fashion. Then, the program must be tested so programmers can make sure that it can be depended upon.

 Finally, the promotion of a programming product must be thoroughly documented so that costumers or anybody else can use it, fix it and extend it..

A program becomes a component in a programming system. This means a collection of interacting programming, coordinated in function and disciplined in format so the assemblage makes it easier to carry out large tasks.

 In order to be a programming system component, a program must be written so that every input and output component conforms in syntax and semantics with precisely defined interfaces.

 The programming systems product, which is the truly useful object, the intended product of most system programming efforts. It is different from the program in all of the above ways.

 Programming is both a tar pit and a creative activity that brings joy to the many people who enjoy the common challenges of programming and creative activities that require a lot of abstract thinking. Testing, documentation and maintenance are very important are very crucial factors for the prevention of a tar pit as far as “computer programming” is concerned.

 It should also be applied in the development of software as far as software engineering goes so that the final product can be reliable and enjoyed by the clients.
