An authoritative guide to implementing CIM in Web-based and directory-enabled environments Common Information Model Offering a framework for managing system elements across distributed systems, the Common Information Model (CIM) has developed into one of the most important pieces of technology since the creation of the World Wide Web. It is a key component of many operating systems and is supported by most major software and hardware companies. Written by the pioneers of CIM, this book provides all the information you'll need to implement this powerful model into a management or managed system. The authors guide you through the modeling basics by introducing the concepts behind information modeling and the fundamentals of CIM. They provide a detailed look at the model itself, show you how to extend the CIM schema, and take you through all the steps needed to implement CIM in Web-based and directory-enabled environments. Providing you with a strong working knowledge of CIM, this book:
• Contains a general overview of object-oriented data design
• Thoroughly examines the Common portion of the model
• Discusses areas of CIM that are still under development
• Presents ideas, concepts, and methodologies for building extensions to the Common model
• Covers critical issues that must be considered when implementing CIM

The model and its ancillary standards are being developed within the Distributed Management Task Force (DMTF). This organization is made up of the leading companies in today' s computing industry and its membership reads like a who's who of high technology companies. The membership consists of operating system vendors, systems manufactures, network systems, and services vendors as well as the leading manufactures of systems management technology. This book was written by the active participants from within this organization and will give the reader the most accurate view of the intent of the model as well as reason that it was developed the way it was.
This book, like the technology, is also a collaborative effort. It has been written by the pioneers of CIM and provides insight into the intent as well as the inner workings of the model. Early in its evolution the team of engineers and architects from the leading companies in the computer industry met every two weeks at locations around the world to develop CIM. The authors of this book were members of that original team and are still actively participating in its ongoing development. Working together on the creation of CIM close bonds were formed making the creation of this book an enjoyable task.
This book provides the reader with an inside view of the Common Information Model starting from modeling basics, for those that are new to information modeling, to how to implement this into a management or managed system.
Concepts (Chapters 1 – 3) This section of the book is designed to familiarize the reader with the concepts behind information modeling and the fundamentals of CIM. It is a good introduction to this model and provides a general overview for anyone that is new to object oriented data design. It also describes how the information can be represented graphically using UML (Universal Modeling Language).
In-depth (Chapters 4-8) These chapters take a detailed look at the model itself, the Common portion of the model, and sections of the model that are used to represent managed elements and their associations. There is also a discussion on those areas of CIM that are still under development. These sections were developed by the folks closely involved with the development from within the DMTF working groups.
Design (Chapters 9-11) These chapters are for those who have a need to extend the CIM schema. It is filled with ideas, concepts, and methodologies that should be considered and followed when building extensions to the Common model.
Implementations (Chapter 12) The book also includes a section on how to implement the model into a management system. This section explains that there is more than turning a logical database into a physical database. This section covers many issues that need to be considered including performance and usability.
For further information on CIM and the current state of the model you should go to the DMTF web site at www. dmtf. org. The Web site also contains a self-paced tutorial that will help the reader to better understand the model and the terms and how to develop your own extensions to the model. Also as new models get completed and approved they will be posted there as well.
This book will provide you the reader with a good working knowledge of the common information model. It should be of assistance when you need to implement a management system using CIM or you are extending the model to implement into a managed. From beginner to the advanced data modeler this book should be a guide and a reference to using the Common Information Model.
