OO Comparison Paper Object-oriented programming is the predominant paradigm in the software development world. Thus‚ it is important to understand how object-oriented programming works. One useful exercise may be to compare and contrast object-oriented programming to more traditional structured programming. I will do just that in this essay. We will review some history‚ give a brief overview of both paradigms‚ and discuss how they are similar and different. First it’s important to understand the

The construction of Object-Oriented Database Management Systems started in the middle 80 ’s‚ at a prototype building level‚ and at the beginning of the 90 ’s the first commercial systems appeared. The interest for the development of such systems stems from the need to cover the modeling deficiencies of their predecessors‚ that is the relational database management systems. They were intended to be used by applications that have to handle big and complex data such as Computer Aided Engineering‚ Computer
