Book Description
From the first chapter, author Carla DeAngelis skillfully explains the normally complex concepts of Data Modeling-a critical success factor in the information-based enterprises of today. Carla tackles complex topics such as Logical Data Models, Modeling Methodologies, Relationships, and Attributes in a clear style that makes it simple for anyone to begin applying them immediately. Once the foundation has been laid, Carla teaches you to develop your own databases with ERwin. You will learn to use the tool to create primary keys and assign attributes, build data relationships with point and click ease, build and edit tables with Erwin's built-in editors, create indexes with the Index Editor, write custom SQL scripts, and process reports with the Report Tools.

Customer Reviews & Comments
ERwin users finally have an independent text to use in addition to application documentation. The work's introduction does a clear job of defining the target audience: "_Data Modeling with ERwin_ is intended for use by novice modelers who are interested in producing quality logical and physical data models using ERwin." ...and it does a good job on the logical side, along with providing a good walkthough of ERwin, specificly ERwin version 3.5.x. Concepts presented are what I would call generaly accepted practices - many organizations follow them with successful results. There are plenty of screenshots of ERwin, as well as data model examples...and it *doesn't* use the common video store sample data model. Part I, Modeling Concepts, includes a high-level overview of a systems development methdology, albeit of the waterfall approach that is not as popular today. It also covers normalization, a topic that I believe is premature at this point of the work. This overview draws heavily on works by Chen, Finkelstein, and Date. This text includes Best Practices, Tips, and basic functionality of ERwin. It does not address any workarounds for known problems, which I find to be its greatest weakness. However, if you are new to ERwin the Best Practices, Tips, and Cautions will be a valuable and timesaving resource. This book is primarily a Logical Data Modelling resource, but it does cover Physical Data Modelling from the ERwin point of view. Only 89 of the 384 pages of the work are devoted to Physical Modelling. If you are new to data modelling as well as ERwin, you will need additional resources on data modelling to support your new skillset. If you are looking for a resource for managing physical data models and databases, you'll have to rely on ERwin documentation and resources such as the ERwin Users Discussion Group. If you are an experienced data modeller or ERwin user, this book might not add value to your reading....but it would be great to have around as a resource for others: developers working to understand modelling, DBAs who are looking to understand logical data modelling, and project managers wanting to understand why this modelling stuff is taking so long....[g].
