Impact Of Object Oriented On Software Development Process

This paper will discuss the difference between procedural modules and object-oriented methods. How both methods work and some of the pro

Now, we will look into what Object Oriented Programming is. Before that we must first understand what an object is, because that is what the entire programming method is based on. An object is something which has a defined state and characteristics of its own. This concept was taken from the real world scenario, where each object we see has those two states. An example would be a cup, it has a height, it has a purpose and it has a specific volume which it can hold. The shape of the cup can also be taken into consideration. In software programming, the object is worked upon by use of methods. The methods are what help two or multiple objects communicate with each other (“Object Oriented Programming”). Thus we can now say, Object oriented programming works on “objects” instead of working directly on the actions as in case of Procedural programming. Although, indirectly we are working on their actions because that is what makes the entire program work. Objects once defined can be used infinite times in a program and we do not have to define them. Thus, object oriented programming focusses more on getting the logic of the program right instead of spending several lines of code trying to get the data definitions right. The most commonly used Object oriented programming languages are Java, C#, PHP and Visual basic designed for .NET framework. An example of PHP object oriented programming would help us understand the actual programming

In Object-orientated approach methodology, a system is viewed as an object (Govardhan & Munassa: 71). This approach intergrades data and processes into objects. It emphasizes the construction and testing of object models. This technique uses UML diagrams such as Communication Diagrams, which show the relationship between objects, Development Diagrams which show how a complete system will be deployed on one or more machines, the Class Diagram and Sequence Diagram.

Programming languages are vast and diverse in their numbers. These different languages use fundamental styles of programming called programming paradigms. These programming paradigms layout the particular design approach that a program will use to solve a problem or achieve an objective. Of the many different types of programming paradigms, some of the more distinguished ones are procedural, functional, logical, and object orientated programming. Recently the object orientated languages have been rising in popularity due to their ability to easily implement large programs. There are many different object orientated programming languages (OOPLs), among them are C#, Java, Ruby, and Python. This essay will compare and contrast two of these languages: Python and Java.

In this first assignment, TWO software development methodologies will be examined using the first four laws given in the prescribed text.

Problems in procedural programming need to be individually addressed as the program is executed whereas in object-oriented programming objects and classes can be referenced throughout the program.

Object–Oriented Analysis and Design (OOAD) approach is important for successful planning and execution of web applications which can function efficiently over long period of time. OOAD approach

In an object-oriented database system encapsulation is achieved if only the operations are visible to the programmer and both the data and the implementation are hidden.

Now a days many organizations are making use of computer based information systems. These information systems were developed decades ago using the procedural programming languages like C, COBOL, BASIC, FORTRAN, and PASCAL etc. Today many organizations are either developing new applications for the business by making use of the advancement in the technology or trying to abstract the functionality of the applications developed using procedural programming languages. The abstraction of functionality is carried out by first abstracting the data flow information and then transforming this information to the appropriate representation. This paper proposes a methodology which abstracts the structural information in the form of a data flow between the statements, function calls, etc. of the ‘C’ program.

For this coursework two kinds of data models can be used. The object oriented data model, Object Oriented Database Management System(OODBMS), or the relational data model, Relational Database Management System(RDBMS). The differences between these two models and the data model to be used are described in this chapter.

As we saw throughout the last forty or so years is that computer systems frequently evolve and that developmental change is inevitable and software development is no stranger to this, which is where agile development or the term that some use agile software development comes into play. This is a concept that searches for alternatives to the traditional way of managing a project and based on the foundation that change is essential to software development. Throughout this paper, we will look at the reasons that brought about the change in thinking with regard to software development, discuss some of the key principles of agile development, methods under agile development and the benefits of the use of agile development. Let’s begin this document with a discussion into what brought about the change in thinking.

OOP, an abbreviation for object-oriented programming is simply code that “attempts to place a new layer of abstraction between the programmer and the data he is working with … this layer will help the programmer develop better code more quickly than he could do before.” (McHale). OOP languages must include four

Effective reuse of software products is reportedly increasing productivity, saving time, and reducing cost of software development. Historically, software reuse focused on repackaging and reapplying of code modules, data structures or entire applications in the new software projects (Prieto-Diaz 1994). Recently, however, it has been acknowledgedas beneficial to

The data and behaviour of the software is organised as a combination of various kinds of objects.
