The object oriented information modeling started in the early 1960’s‚ but at the time it was not very popular. It is only recently that object oriented programming has become popular. It was designed for the purposes of creating simulations and was developed by Kristen Nygaard and Ole-Johan Dahl in Norway. The term “object oriented information modeling” was first used by Xerox PARC in their Smalltalk programming language. The term was used to refer to the process of using the objects as the foundation

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

Techniques For Object-Oriented Programs Submitted in partial fulfillment of the requirements for the award of the degree of Master of Computer Application (2009-2012) ABSTRACT Object-oriented programs involve many unique features that are not present in their conventional counterparts. Examples are message passing‚ synchronization‚ dynamic binding‚ object instantiation‚ persistence‚ encapsulation‚ inheritance‚ and polymorphism. Integration testing

Java programming‚ inheritance plays an important role in a programmer’s ability to reuse codes. Inheritance in basic terms allows a subclass to use the variables and methods of a superclass. When a programmer creates a subclass with new variables and methods‚ it can easily use the superclass’s methods and variables by extending without having to rewrite the entire superclass over again. Therefore‚ the subclass inherits variables and methods from the superclass. In this sense‚ inheritance helps

11. Compare and contrast abstract classes and interfaces. Why would you use an abstract class? Why would u use an interface? -abstract class‚ ex: (public abstract class Employee{...}) -For related classes only‚ inheritance (last week examples) -extends keyword -contains both instance and static variables -contains both abstract and concrete methods only An abstract class is only to be sub-classed (inherited from). In other words‚ it only allows other classes to inherit from it but cannot
