Advantages And Disadvantages Of Object Orientated Programming

962 Words2 Pages

What is object-orientated programming? Object-orientated programming is methodology which is organized around objects and not actions. The perspective that this approach takes is that it is easier to compare objects. Object-orientated programming can be used in conjunction with UML, and within Object-orientated programming and there are various different methods. Object-orientated programming can be defined as constructing a model of a real world through combining data and actions. History of Object-orientated programming Object orientated programming first began in the 1960’s. Simula 67 was the first programming language that used objects and was developed by Kristen Nygaard and Ole-Johan Dahi in Norway. Exforsys states (2006) “The term …show more content…

Advantages and Disadvantages obect orientated programming has many advantages, one of these is the fact that the objects created : Jeffrey L. Popyack (2012) "can easily be reused in other programs." The Saylor Foundation also states that object orientated programming allows “Improved software-development productivity" and "Improved software maintainability” through the modular structure of the development. Some of the disadvantages of object orientated programming are as follows; Andrew Hardwick. (2007} states that it is “not ideal for doing small quickly-written one-off programs”. Another drawback of object orientated programming is that it requires a lot of prior planning and so it doesn’t hold the advantages of developing in increments in other methods such as agile Object-orientated …show more content…

Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also

The third stage is analyze with the purpose of developing methods and theories that will best suit the solving of the problem; it is also a stage of detecting cause-and-effect ties of the processes. The fourth stage is improve, it is aimed at generating ideas for reaching the desired process improvement.

Iteration allows greater understanding of a project through successive refinements and addresses a projects highest risk items at every stage of its lifecycle. Ideally each iteration ends up with an executable release – this helps reduce a projects risk profile, allows greater customer feedback and help developers stay focused.

    Compilers collect and reorganize (compile) all the instructions in a given set of source code to produce object code. Object code is often the same as or similar to a computer's machine code. If the object code is the same as the machine language, the computer can run the program immediately after the compiler produces its translation. If the object code is not in machine language, other programs—such as assemblers, binders, linkers, and loaders—finish the translation.

  • Unified Modeling Language

    The Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The key is to organize the design process in a way that clients, analysts, programmers and other involved in system development can understand and agree on. The UML provides the organization. The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thin to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.

Through requirements engineering, there is an examination of the context of software work performed. It is essential for the software engineering team to understand all requirements of a problem before the team tries to solve the problem. An identification of specific needs that the design and construction must address is also included. Further is a need for the identification of the priorities that guides the order for the completion of work. This i...

This program was developed by Bjarne Stroustrup. The name C++ was originally C, but was renamed as a pun to involve the increment operator. This program has influence a plethora of other programming languages; these include Java, C#, and the newer versions of C.
