Data Model Patterns: A Metadata Map not only presents a conceptual model of a metadata repository but also demonstrates a true enterprise data model of the information technology industry itself. It provides a step-by-step description of the model and is organized so that different readers can benefit from different parts. It offers a view of the world being addressed by all the techniques, methods, and tools of the information processing industry (for example, object-oriented design, CASE, business process re-engineering, etc.) and presents several concepts that need to be addressed by such tools. This book is pertinent, with companies and government agencies realizing that the data they use represent a significant corporate resource recognize the need to integrate data that has traditionally only been available from disparate sources. An important component of this integration is management of the "metadata" that describe, catalogue, and provide access to the various forms of underlying business data. The "metadata repository" is essential to keep track of the various physical components of these systems and their semantics. The book is ideal for data management professionals, data modeling and design professionals, and data warehouse and database repository designers.

The regenerative capacity of the liver has been recognized for centuries, but when it is overwhelmed by insulting stimuli or is chronically damaged, its regenerative capability is substantially reduced or lost. Researchers have been working to find solutions to cure failing human liver function. Given the ability of stem cells to self- renew and differentiate into specialized cell liver types, they represent an attractive strategy to replace lost liver function. This book begins by outlining the complex nature of human liver disease and proceeds to examine the potential that stem cell-based approaches have to offer.
