This book provides the foundation and understanding necessary for
proper design of databases for today's distributed and
multi-database architectures. Introductory chapters help novices
understand essential topics such as SQL, relational databases,
transaction processing, and deadlock detection, while subsequent
sections dealing with homogeneous, distributed databases,
heterogeneous multi-databases, and federated databases enable
readers to understand the complexities of distributed database
design. Packed with over 200 illustrations, 50 equations, and two
full chapters of examples.
Business data integration is a complex problem that must be solved
when organizations change or enhance their internal structures. The
goal of this book is to present a simple yet thorough resource that
describes the challenges of business data integration and the
solutions to these challenges such as schema integration,
illustrated through an Operational Data Store (ODS) case study. The
book contains three sections spanning ten chapters. Section I,
Foundational Concepts, will provide you with the necessary basic
concepts and discuss schema integration. Section II, Preparation
and Design, introduces the case study and we will reverse engineer
each of the data sources to create a set of data dictionary reports
which will provide us with the meta data we need to apply the
schema integration process. Section III, Physical Implementation,
will present scripts to populate each of the source databases and
spreadsheets and use reports to create Extract, Transform, and Load
(ETL) specifications.
