The Object Oriented Model The object-oriented(OO) model actually had its beginning in the 1970s‚ but it did not see significant commercial use until the 1990s. This sudden emergence came from the inability of then existing RDBMSs (Relational Database Management Systems) to deal with complex data types such as images‚ complex drawings‚ and adio-video files. The sudden explosion of the Internet and the World Wide Web created a sharp demand for mainstream delivery of complex data. An object is a

Essay Object oriented programming was developed because limitation was discovered in earlier approaches to programing. The evolution to the object oriented programming is based on the following previous languages. Evolution in computer programming languages: In the earlier time‚ at the beginning of programming the “Punch Card“ was used for the programming purpose. Then with the passage of time human tried to work on the binary digits called “Machine Language”. 1. Machine Language In the machine

Object oriented system development is an approach to system design in which the development process of the entire system is decomposed into smaller independent stages called objects. It is considered to be a partial lifecycle. Each object and its attributes are abstract entities and is characterized by its functionality. Using the functionality of objects they can further be grouped in classes. Object oriented system development is characterized by reusability of components i.e. Objects that

OBJECT-ORIENTED DOCUMENTATION Johannes Sametinger C. Doppler Laboratory for Software Engineering Johannes Kepler University of Linz A-4040 Linz‚ Austria Abstract Object-oriented programming improves the reusability of software components. Extensive reuse of existing software enhances the importance of documentation. In order to increase the productivity in documenting and to make the structure of documentation better suitable for object-oriented software systems‚ we suggest to apply object-oriented

To do this‚ you’ll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then‚ as each object is created‚ its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member
