Object-Oriented Analysis and Design
UML is used to specify, visualize, construct, and document the artifacts major elements of the software system. It was initially developed by Grady Booch, Ivar Jacobson, and James Rumbaugh in at Rational software, and its further development was carried out through In , it got adopted as a standard by the Object Management Group.
The UML stands for Unified modeling language, is a standardized general-purpose visual modeling language in the field of Software Engineering. It is used for specifying, visualizing, constructing, and documenting the primary artifacts of the software system. It helps in designing and characterizing, especially those software systems that incorporate the concept of Object orientation.
It describes the working of both the software and hardware systems. The OMG was established to build an open standard that mainly supports the interoperability of object-oriented systems.
It is not restricted within the boundaries, but it can also be utilized for modeling the non-software systems. Before moving ahead with the concept of UML, we should first understand the basics of the conceptual model. A conceptual model is composed of several interrelated concepts. It makes it easy to understand the objects and how they interact with each other. This is the first step before drawing UML diagrams. OO is an analysis of objects, and design means combining those identified objects.
So, the main purpose of OO analysis is identifying the objects for designing a system. The analysis can also be done for an existing system. The analysis can be more efficient if we can identify the objects. Once we have identified the objects, their relationships are then identified, and the design is also produced. The main purpose of OO analysis is identifying the objects and describing them correctly.
After the objects are identified, the designing step is easily carried out. It is a must to identify the objects with responsibilities. Here the responsibility refers to the functions performed by the objects. Each individual object has its own functions to perform. The purpose of the system is fulfilled by collaborating these responsibilities.
This phase mainly emphasizes on meeting the requirements. In this phase, the objects are joined together as per the intended associations. After the association is completed, the designing phase also gets complete. This is the last phase that comes after the designing is done. As the UML is a modeling language used to model software as well as non-software systems, but here it focuses on modeling OO software applications. The OO languages influence the programming world as they model real world objects.
The strength of these three approaches is utilized by the UML to represent more consistency. This UML tutorial is made for both beginners and professionals, to help them understand the fundamental concept of UML. After completion of this tutorial, you will find yourself at a moderate level of expertise from where you take yourself to the next level.

UML came into existence after the introduction of object-oriented concepts to systemize and consolidate the object-oriented development, due to the absence of standard methods at that time. The UML diagrams are made for business users, developers, ordinary people, or anyone who is looking forward to understand the system, such that the system can be software or non-software. Thus it can be concluded that the UML is a simple modeling approach that is used to model all the practical systems.
It is interrelated to object-oriented analysis and design. It is used to visualize the workflow of the system. It is a pictorial language, used to generate powerful modeling artifacts. Conceptual Modeling Before moving ahead with the concept of UML, we should first understand the basics of the conceptual model. Following are some object-oriented concepts that are needed to begin with UML: Object: An object is a real world entity. There are many objects present within a single system.
It is a fundamental building block of UML. Class: A class is a software blueprint for objects, which means that it defines the variables and methods common to all the objects of a particular type. Abstraction: Abstraction is the process of portraying the essential characteristics of an object to the users while hiding the irrelevant information.
Basically, it is used to envision the functioning of an object. Inheritance: Inheritance is the process of deriving a new class from the existing ones. Polymorphism: It is a mechanism of representing objects having multiple forms used for different purposes. Encapsulation: It binds the data and the object together as a single unit, enabling tight coupling between them. OO Analysis and Design OO is an analysis of objects, and design means combining those identified objects.
The purpose of OO is given below: To identify the objects of a system. To identify their relationships. To make a design that is executable when the concepts of OO are employed. Following are the steps where OO concepts are applied and implemented: Step 1: OO Analysis The main purpose of OO analysis is identifying the objects and describing them correctly. Step 2: OO Design This phase mainly emphasizes on meeting the requirements.
Step 3: OO Implementation This is the last phase that comes after the designing is done. Prerequisites No particular skills are required as a prerequisite before starting with this tutorial. Problems We assure you that you will not find any difficulty in this tutorial.

This course is part of the Software Design and Architecture Specialization. This course takes Java beginners to the next level by covering object-oriented analysis and design. You will discover how to create modular, flexible, and reusable software, by applying object-oriented design principles and guidelines. You will be challenged in the Capstone Project to apply your knowledge of object-oriented design by evolving and documenting the Java codebase for an Android application with corresponding UML documentation. Good software design begins before coding.
The second edition of this textbook includes revisions based on the feedback on the first edition. In a new chapter the authors provide a concise introduction to the remainder of UML diagrams, adopting the same holistic approach as the first edition. Using a case-study-based approach for providing a comprehensive introduction to the principles of object-oriented design, it includes:. The focus of the book is on implementation aspects, without which the learning is incomplete.

Object-oriented analysis and design OOAD is a technical approach for analyzing and designing an application, system, or business by applying object-oriented programming , as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality. OOAD in modern software engineering is typically conducted in an iterative and incremental way. The intention is for these to be continuously refined and evolved, driven by key factors like risks and business value. In the early days of object-oriented technology before the mids, there were many different competing methodologies for software development and object-oriented modeling , often tied to specific Computer Aided Software Engineering CASE tool vendors.
In the object-oriented design method, the system is viewed as a collection of objects i. The state is distributed among the objects, and each object handles its state data. For example, in a Library Automation Software, each library representative may be a separate object with its data and functions to operate on these data. The tasks defined for one purpose cannot refer or change data of other objects.

Partha Pratim Das. The complexity of software systems is ever on the rise more complex problem domains being attempted complex embedded systems , ever growing number of developers engaged in increasingly intricate development processes to turnaround in shorter and shorter time, flexibility of software and models of implementation being stretched to the limit with XaaS, platforms getting challenging with widely expanding distribution, cloud computation etc. Hence the analysis and design of software require well-organized and structured approaches to manage the challenges of complexity even more than ever before. Over the past two decades, methods of Object-Oriented Analysis, Design and Programming have proved to be effective solutions in handling the inherent complexity of software design, development, testing and maintenance.

Я не знаю, кто вы такой и чего хотите, но если вы немедленно отсюда не уйдете, я вызову службу безопасности отеля и настоящая полиция арестует вас за попытку выдать себя за полицейского офицера. Беккер знал, что Стратмор в пять минут вызволит его из тюрьмы, но понимал, что это дело надо завершить совершенно. Арест никак не вписывался в его планы.
На экране ВР у входа толпились и множились хакеры, число их за последние минуты удвоилось. Теперь оно начало расти в геометрической прогрессии. Хакеры подобны гиенам: это одна большая семья, радостно возвещающая о любой возможности поживиться.
Слова приятеля его очень удивили. Дело в том, что АНБ не только существовало, но и считалось одной из самых влиятельных правительственных организаций в США и во всем мире. Уже больше полувека оно занималось тем, что собирало электронные разведданные по всему миру и защищало американскую секретную информацию. О его существовании знали только три процента американцев. - АНБ, - пошутил приятель, - означает Агентство, которого Никогда не Было.
Они, вполне естественно, хотят предотвратить распространение Цифровой крепости, поэтому послали на поиски ключа человека по имени Дэвид Беккер. - Откуда вам это известно. - Это не имеет отношения к делу. Нуматака выдержал паузу.
- Я никогда не послал бы туда Дэвида, если бы считал, что это связано хоть с малейшей опасностью. - Он улыбнулся. - Поверь .
Он просиял. - Второй раз за один вечер. Что подумают люди.
