Abstract This paper is about the evolution of Object-oriented technology in software design and implementation and its role in current market for developing web based products or server side scripting. Many Object-oriented languages have come in market but among them companies prefer to use open source OO languages such as Java, C++, C# .NET, and Visual Basic .NET etc. The demand for these languages has increased because the cost of licensing is very less or nothing. As these languages are open source, it easy to find relevant libraries and source code for the developers while developing a product. The cost of the infrastructure such as development IDE’s or testing tools are also minimal or available for free. Hence all these factors decrease the cost of developing a product using Object-oriented technology. The basic concept of OO language is Objects. An Object is a combination of attributes and behaviors. An object is an entity that contains
There are three types of Java; the deployment platform, object oriented programming language, and the application interface portfolio and each one brings their own features to visionary and enterprise operators. The open doors the Java present are to some extent obstructed by obstacles to adoption needing plans and determination to conquer. The Java deployment platform provides designers a growing horizon, giving them an entrance to the innovative markets, the wide range use of the platform hinges on major advantages regarding the ease of design; particularly, when used as a portfolio of application features and as a general-purpose programming language (Coffee, 2004).
“During the object-oriented analysis (OOA) phase object-modeling techniques are used to analyze the functional requirements for a system and create models which reflect the logical design of the system. During the object-oriented design (OOD) phase of the system, models are elaborated upon to include implementation specific details that show how the physical design of the system will come together. OOA focuses on what the system does (its static structure and behavior), OOD on how the system does it (its run-time implementation).”
Purpose of this assignment: To demonstrate understanding of principles of software design, in relation to specific programming scenarios, and how these principles relate to the software development life cycle.
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
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.
This report will embrace why different programming languages have been developed. It will also compare and contrast event driven programming and object oriented programming languages. Furthermore it will explain the benefit of having data type’s available to the programmer.
Since the software has been evolving with time, the code has become more complex, hence the software development cost’s major part is given to software maintenance. Refactoring or restructuring is the problem which implies the need of techniques that reduce software complexity by improving software quality. Refactoring is “the process of changing a software system in such a way that it does not alter the external behavior of the code, yet improves its internal structure”. The classes,
Code Reusability: The object-oriented features allow the high reusability of code. For example, when a new object is created, it will inherit all the attributes and methods of the class of which it is an object of, in addition to all the parent classes of that class.
An OOP language can use a group of objects that will send message when they are called for a request for a specific service or information. Objects is able to pass or receive messages or process information in the form of data. The reason we use OOP is that it makes maintaining code easier and faster to change and modify existing code. That mean we cut down on development time and changing the programme much easier. Also Object-Orientated Programming is more efficient at memory management, and thus makes it more effective towards Procedural, where you must manage your own memory usage.
Object-oriented programming language is a high-level programming language based on the object. Data hiding, Inheritance, and polymorphism such basic features of this programming languages. this method is not used for computer programming Until the early 1990s. But, mostly use this language for modern computer programming.
The focus of object-oriented view is on the elaboration of design classes that belong to both problem and infrastructure domains. Classes are elaborated by specifying messaging details, identifying interfaces, defining attribute data structures, and describing process flow for operations. In traditional view, three components are refined, they are control modules, domain modules, and infrastructure modules. To generate programming language source code detailed representations of data structures, interfaces and algorithms for each program are to be created.
Insightfully mapping out the technological advancements in software development from its beginnings somewhere in the late 1940’s to the current modern age. There is more than enough compelling evidence that software technology has laid a strong impact on all economic and social aspects of our modern day living. Thus, a systematic approach towards high quality software development is required due to an increasingly quality oriented market and competitive business world.

INTRODUCTION: Software has been part of modern society for more than 50 years. The software process is the foundation for engineering software. Within the context of his book, Pressman defines “A software process as a framework for the tasks that are required to build high-quality software.” [1]. This paper introduces and discusses some of the Software methodologies and issues. METHODOLOGIES RELATED TO WEB DEVELOPMENT: In Software Engineering, a software development methodology is a division of software development work into different phases with the purpose of better planning and management. The methodologies may include pre-definition of
Object-oriented programming is a programming paradigm based on the concept of objects rather than algorithms, this may contain data in the form of fields. it aims to incorporate the advantages of modularity and
