Phase 1 Discussion Board 2: Object Oriented Techniques IT110_1302A-01 Introduction to Programming Instructor: Steve Montgomerie Jeffrey Graham April 10‚ 2013 Colorado Technical University In order to better understand object oriented programming (OOP) this paper will discuss the similarities and differences between OOP and procedural programing (PP). It will also provide information on four basic object oriented concepts of objects‚ classes‚ methods‚ and polymorphism. The some similarities

the persistent data‚ so application architecture has much more impact on performance than is the case with an RDB. Or to put it another way‚ when using an OODB the application architect has much more power to optimize performance than when using an RDB. Consequently the application architecture has more effect on performance and scalability than the choice of OODB product. To effectively exploit an OODB a use-case driven approach is recommended‚ as this informs the entire design of the application

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 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

Ans: Object oriented programming organizes a program around its data‚i.e.‚objects and a set of well defined interfaces to that data.An object-oriented program can be characterized as data controlling access to code. 2)what is the difference between Procedural and OOPs? Ans: a) In procedural program‚ programming logic follows certain procedures and the instructions are executed one after another. In OOPs program‚ unit of program is object‚ which is nothing but combination of data and code

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

The Three Tenets of Object-Oriented Programming Languages According to Bjarne Stroustrup‚ author of the C++ programming language‚ for a language to call itself object-oriented‚ it must support three concepts: objects‚ classes‚ and inheritance. However‚ object-oriented languages have come to be more commonly thought of as those languages built on the tripod of encapsulation‚ inheritance‚ and polymorphism. The reason for this shift in philosophy is that over the years we’ve come to realize that encapsulation
