Experienced application developers often invest more time in building models than they do in actually writing code. Why? Well-constructed models make it easier to deliver large, complex enterprise systems on time and within budget. Now, a new framework advanced by the Object Management Group (OMG) allows developers to build systems according to their core business logic and data—independently of any particular hardware, operating system, or middleware.
Model Driven Architecture (MDA) is a framework based on the Unified Modeling Language (UML) and other industry standards for visualizing, storing, and exchanging software designs and models. However, unlike UML, MDA promotes the creation of machine-readable, highly abstract models that are developed independently of the implementation technology and stored in standardized repositories. There, they can be accessed repeatedly and automatically transformed by tools into schemas, code skeletons, test harnesses, integration code, and deployment scripts for various platforms.
Written by three members of OMG’s MDA standardization committee, MDA Explained gives readers an inside look at the advantages of MDA and how they can be realized. This book begins with practical examples that illustrate the application of different types of models. It then shifts to a discussion at the meta-level, where developers will gain the knowledge necessary to define MDA tools.
Highlights of this book include:
The MDA framework, including the Platform Independent Model (PIM) and Platform Specific Model (PSM)
OMG standards and the use of UML
MDA and Agile, Extreme Programming, and Rational Unified Process (RUP) development
How to apply MDA, including PIM-to-PSM and PSM-to-code transformations for Relational, Enterprise JavaBean (EJB), and Web models
Transformations, including controlling and tuning, traceability, incremental consistency, and their implications
Relationships between different standards, including Meta Object Facility (MOF), UML, and Object Constraint Language (OCL)
The advent of MDA offers concrete ways to improve productivity, portability, interoperability, maintenance, and documentation dramatically. With this groundbreaking book, IT professionals can learn to tap this new framework to deliver enterprise systems most efficiently.
About the Author
Anneke Kleppe is a consultant and adviser at Klasse Objecten, which she founded in 1995 to train and coach companies on the use of object technology, modeling, and MDA. She was intensively involved in the development of the Unified Modeling Language (UML) and the new UML 2.0 standard. The author of several books, Anneke started a knowledge center for object technology at KPN Research in Leidschendam, Netherlands. She is a member of the authoring team of the OCL 2.0 standard, where she has a special focus on the definition of the semantics of the OCL.
Jos Warmer is the primary author of the OCL standard. He is an active member of the Unified Modeling Language (UML) Revision Task Force, which defined the revisions in the UML 2.0 standard. Previously he was a member of the UML core team, where he was responsible for the development of the Object Constraint Language (OCL). The author of several books and numerous international articles, Jos is an advisor on the UML method and techniques at the De Nederlandsche Bank.
