Introduction to Object-Orientation and the UML The prevalence of programming languages such as Java, C++, Object Pascal, C#, and Visual Basic make it incredibly clear that object-oriented technology has become the approach of choice for new development projects. Although procedural languages such as COBOL and PL/1 will likely be with us for decades it is clear that most organizations now consider these environments as legacy technologies that must be maintained and ideally retired at some point. Progress marches on. My experience is that agile software developers, be they application developers or Agile DBAs, must minimally have an understanding of object orientation if they are to be effective. This article overviews the fundamental concepts and techniques that application developers use on a daily basis when working with object technology. Table of Contents 1. Agile software developers, including Agile DBAs, need to be familiar with the basic concepts of object-orientation. 2. 2.1 Core UML Diagrams 2.1.1 UML Use Case Diagrams 4.
Impact on Introducing Object Oriented Software Development Methodologies Impact on Introducing Object Oriented Software Development Methodologies Paul SullivanESBI Computing Ltd., DublinPat CaffreyESBI Computing Ltd., Dublin 1.0 Introduction The SCOOP project objective was to enable an holistic view of the impact of introducing OO software development methodologies and tools. Selection of an OO methodology. 2.0 Selection of OO methodology To find as many OO methodologies in the marketplace, the Internet was used to find a list of books containing OO methodologies. The book "A comparison of Object Oriented Methodologies" was used as a guideline to selecting the following methodologies in more detail: 2.1 Fusion The Fusion method is a combination of different sections of different methods. Object- Oriented Modelling and Design, Prentice Hall International 1991 OMT along with Booch is considered to be one of the best Object-Oriented methodologies. The Unified Method V 0.8 The Unified Modelling Language V 0.91 2.4 Selected Methodology - Booch Development Environment
Object-Oriented Characteristics - Programming Paradigms In a way encapsulation protect the system, since it hides stuff that can be vulnerable to malicious attack. There are also many other drawbacks to create a system without encapsulation. You can find it out in our book chapter. Inheritance "Modeling the Similarity" Similarities often exist in the world. George W. Polymorphism "Same Function different behavior" The word “Polymorphism” comes from two Greek words, “many” and “form”. Examples that apply Inheritance and Polymorphism A video that shows the important concept of inheritance and polymorphism supported by examples and java codes. In the video, two new concepts are mention and here's a short introduction them:Interface A collection of attributes and abstract methods. For more details and examples of the 4 main Object-Oriented characteristics can be found at Book Chapter.
TRANSITION TO OBJECT-ORIENTED SOFTWARE DEVELOPMENT Mohamed Fayad, Mauri Laitinen Preface The popularity and sophistication of object-oriented (OO) technology has grown dramatically over the last few years. Several organizations sponsored early attempts to use OO technology that demonstrated its potential for delivering high-quality software. Then, full-scale projects were developed that proved the promise. The central claim of this book is that OO technology has become not just practical, it has become the only effective way to deal with the complexity and reliability demanded of current software. We maintain a relentlessly practical viewpoint about software development. First, software is difficult to develop. Second, making the transition to object-oriented software engineering will take time, money, tools, and training. Third, there is no ultimate development method. This is not a how-to book about object-oriented programming. Major Book Themes This book covers transition issues by answering the following questions. Minor Book Themes
Object Oriented modelling & it differ from dynamic model - mcasolvedassignment What is Object Oriented modelling? Explain object model. Also explain how it is different from dynamic model. Object-Oriented Modelling Object oriented modelling is a method of analysis for modelling knowledge & information about a system where the system is divided into elements called objects. An object comprises of variables & methods. Object-Oriented Modeling, or OOM, (Object Oriented Programming - OOP) is a modeling paradigm mainly used in computer programming. Object Model has two related but distinct meanings: 1. 2. Object model is different from dynamic model: An object model describes static structure of objects in a system and their relationships where as a dynamic model shows the time-dependent behaviour of the system and the objects in it. The following steps are performed in constructing an Object Model: Identify classes, attributesIdentify relationships, associationsIdentify hierarchyObject Modelling is used to specify structure of the objects that exist in the problem domain.
