In 1992 he co-authored the book Object-Oriented Software Engineering - A Use Case Driven Approach,[4] which laid the foundation of the OOSE system engineering method and helped to popularize use cases for capturing functional requirements, especially in software development. In 1994 he published a book about use cases and object-oriented techniques applied to business models and business process reengineering.[5]
At the same time, Grady Booch and James Rumbaugh worked at unifying their object-oriented analysis and design methods, the Booch method and Object Modeling Technique (OMT) respectively. In 1995 Ivar Jacobson joined them and together they created the Unified Modelling Language (UML), which includes use case modeling. UML was standardized by the Object Management Group (OMG) in 1997.[6] Jacobson, Booch and Rumbaugh also worked on a refinement of the Objectory software development process. The resulting Unified Process was published in 1999 and promoted a use case driven approach.[7]
How can software developers, programmers and managers meet the challenges of the 90s and begin to resolve the software crisis?This book is based on Objectory which is the first commercially available comprehensive object-oriented process for developing large-scale industrial systems. Ivar Jacobson developed Objectory as a result of 20 years of experience building real software-based products. The approach takes a global view of system development and focuses on minimizing the system's life cycle cost. Objectory is an extensible industrial process that provides a method for building large industrial systems.
Unified Modeling Language (UML) is a language for system specification that was created by several modeling specialists to consolidate and standardize a great number of languages and development methods of object-oriented software appearing in the late 1980s and early 1990s. UML comprises a set of diagrams used to specify, model, construct and document software systems. UML diagrams can be used in both the development of simple systems and in large and complex systems, being also used to model other non software systems.
In the middle of the 1990s, three authors of object-oriented software development methods, James Rumbaugh (Object Modeling Technique (OMT)), Grady Booch (Object-Oriented Design (OOD)) and Ivar Jacobson (Object-Oriented Software Engineering (OOSE), also proposed the Use Cases), start a project for unifying their methodologies, working together at Rational Software, creating the UML (Rumbaugh et al. 1999). In 1997, the...
Dr. Ivar Jacobson is a father of use cases, the Unified Modeling Language, and the Rational Unified Process. He has contributed to modern business modeling and aspect-oriented software development. He is the principal author of seven influential and best-selling books including Business Process Reengineering with Objects, Object Oriented Software Engineering: A Use Case Driven Approach, and Aspect-Oriented Software Development with Use Cases. Most recently, Ivar has been working on how to deal with methods and tools in an agile and lean way.
"A refreshingly new approach toward improving use-case modeling by fortifying it with aspect orientation."
--Ramnivas Laddad, author of AspectJ in Action "Since the 1980s, use cases have been a way to bring users into software design, but translating use cases into software has been an art, at best, because user goods often don''t respect code boundaries. Now that aspect-oriented programming (AOP) can express crosscutting concerns directly in code, the man who developed use cases has proposed step-by-step methods for recognizing crosscutting concerns in use cases and writing the code in separate modules. If these methods are at all fruitful in your design and development practice, they will make a big difference in software quality for developers and users alike.
--Wes Isberg, AspectJ team member"This book not only provides ideas and examples of what aspect-oriented software development is but how it can be utilized in a real development project."
--MichaelWard, ThoughtWorks, Inc."No system has ever been designed from scratch perfectly; every system is composed of features layered in top of features that accumulate over time. Conventional design techniques do not handle this well, and over time the integrity of most systems degrades as a result. For the first time, here is a set of techniques that facilitates composition of behavior that not only allows systems to be defined in terms of layered functionality but composition is at the very heart of the approach. This book is an important advance in modern methodology and is certain to influence the direction of software engineering in the next decade, just as Object-Oriented Software Engineering influenced the last."
--Kurt Bittner, IBM Corporation"Use cases are an excellent means to capture system requirements and drive a user-centric view of system development and testing. This book offers a comprehensive guide on explicit use-case-driven development from early requirements modeling to design and implementation. It provides a simple yet rich set of guidelines to realize use-case models using aspect-oriented design and programming. It is a valuable resource to researchers and practitioners alike."
--Dr. Awais Rashid, Lancaster University, U.K., and author of Aspect-Oriented Database Systems "AOSD is important technology that will help developers produce better systems. Unfortunately, it has not been obvious how to integrate AOSD across a project''s lifecycle. This book shatters that barrier, providing concrete examples on how to use AOSD from requirements analysis through testing."
--Charles B. Haley, research fellow, The Open University, U.K.
Aspect-oriented programming (AOP) is a revolutionary new way to think about software engineering. AOP was introduced to address crosscutting concerns such as security, logging, persistence, debugging, tracing, distribution, performance monitoring, and exception handling in a more effective manner. Unlike conventional development techniques, which scatter the implementation of each concern into multiple classes, aspect-oriented programming localizes them.
