Object Oriented Analysis Design (OOAD) Object Oriental Analysis Design is a hands on approach used to model and create systems as a group of interacting objects. The term “Object”, describes a form of entity or “thing” of concern. Objects are typically modeled after real world entities or concepts. For the business analyst, examples of objects may range from; invoice, product, contract, etc. Objects usually contain attributes that can be set to specific values. With Object Oriented Approach to system design, it tries to lessen the impact of problems by combining related data and functions into the same module. Objects In the real world can be characterized by two things; data and behavior. For example, a television is an object and possess data in the sense that it is tuned to a particular channel, the scan rate is set to a certain value, the contrast and brightness is a particular value and so on. The television object can also "do" things. The television can switch on and off, the channel can be changed, and so on. Below is a graphical representation of a single object and its characteristics: …show more content…
“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).”
This paper will discuss the difference between procedural modules and object-oriented methods. How both methods work and some of the pro
Object analysis is the process through which we can evaluate the function of an object, and evaluate the features including the benefits and disadvantages of that object. Furthermore, some objects are of high importance for us as they help us to spend our lives with ease and comfort. As I am studying in the US, the major problem I faced after my admission is the communication problem. I use this language because it is my second language and I find it really hard to communicate effectively with my teachers and the friends whom I am living with.
Logical and physical models represent the key elements and processes of the software development. The logical model describes the processes, and data, in as much detail as possible, without giving regard to how the system will be implemented. Logical data models include
Here the model depicts five use the logical view, the process view, the physical view, development view and use case view. These views of the system are concurrent and each offers its own
Inheritance is when a class (subclass) has the same attributes and methods of another class (parent class); this is done by creating class from an existing class. While a subclass has properties derived for the parent class, it can also have properties of its own.
This research paper will be focus on different software modeling techniques. Software modeling is concerned with development process of software. Software modeling is central part of almost all activities that took place in software development. These models help us to envision a system according to our requirement by describing the structure and behavior of the system. There are three basic techniques of software modeling; object oriented modeling, dynamic modeling and functional modeling. Object oriented modeling concept start in 1990s, its basic building block is object that is the instant of any class, and here class is a template containing attributes and methods of objects. Classes and their relationships are present in class diagram. As a class have many type of relations with other class within a class diagram. These relationships are about inheritance and some are about
This are the operation done like OS and assembly to meet the standard to different
As design moves forward, the development teams begin to generate a tremendous amount of detailed information about the system. Modules, classes, data fields, data structures, forms, reports, methods, subroutines, and tables are all being defined in substantial detail in the design model. The key design tasks are decomposing the application into layers, clients, and servers, distributing the “pieces” across hardware platforms, and defining the physical network and protocols.
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.
OOPLs have been around since the 1960’s (Deitel, Java How to Program). They handle tasks by viewing them as a group of different objects. Objects are created from a class which could be considered the blueprint. Objects contain data stored in fields, and the procedures which manipulate the data are known as methods. These objects can interact with each other. There are some key elements of OOPLs, such as code reusability. In OOPLs, through what is known as inheritance, code can be reused. Think of a cup, it is an object. It contains a liquid and overflows when it’s full. If you wanted to program a coffee mug, wine glass, or sports bottle, you could reuse the code for a cup though inheritance, then add extra fields
By using object-oriented, you can solve problems. The object-oriented language is a type of programming that is kept in a single unit called object. Meaning that the only way user can access the data is by using the objects methods.
Object-oriented programming (OOP) and procedural programming are two programming paradigms. Procedural programming is a method of writing software. It is a programming practice centered on the procedures or actions that take place in a program. Object-oriented programming centers on the object. Object-oriented programming creates objects from abstract data types that encapsulate data and functions together (Gaddis 2010). There are many similarities
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
Software architecture design is an important aspect of our daily lives whether we know it or not. There are so many different systems that we interact with on a daily basis that we do not recognize are closely tied to software architecture decisions. These systems handle things from stoplights, electricity, televisions, communications, and many other things. Another example of a software system involved with our life is a system that powers banks and financial networks
