Object-oriented analysis and design can offer an approach that facilitates logical, rapid, and thorough methods for creating new systems responsive to a changing business landscape. Object-oriented techniques work well in situations in which complicated information systems are undergoing continuous maintenance, adaptation, and redesign. In this chapter, we introduce the unified modeling language (UML), the industry […]

Object-Oriented Concepts – Objects/Classes/Inheritance
Object-oriented programming differs from traditional procedural programming by examining the objects that are part of a system. Each object is a computer representation of some actual thing or event. General descriptions of the key object-oriented concepts of objects, classes, and inheritance are presented in this section, with further details on other UML concepts introduced later […]

Now that we have covered the fundamental concepts of object-oriented systems analysis and design, we need to examine ways to create classes and objects from the business problems and systems we are facing. One way to begin enacting the object-oriented approach is to start thinking and talking in this new way. One handy approach is […]
Read More...The Unified Modeling Language (UML) Concepts and Diagrams
The UML approach is well worth investigating and understanding, due to its wide acceptance and usage. UML provides a standardized set of tools to document the analysis and design of a software system. The UML toolset includes diagrams that allow people to visualize the construction of an object-oriented system, similar to the way a set […]
Read More...Use Case Modeling
UML is fundamentally based on an object-oriented analysis technique known as use case modeling, which was introduced in Chapter “Understanding and Modeling Organizational Systems“. A use case model shows a view of the system from the user perspective, thus describing what a system does without describing how the system does it. UML can be used […]
