  Beginning Database Design: From Novice to Professional, 2 edition
Beginning Database Design: From Novice to Professional, 2 edition By Clare Churcher
2012 | 252 Pages | ISBN: 1430242094 | EPUB + PDF | 10 MB + 14 MBBeginning Database Design, Second Edition provides short, easy-to-read explanations of how to get database design right the first time. This book offers numerous examples to help you avoid the many pitfalls that entrap new and not-so-new database designers. Through the help of use cases and class diagrams modeled in the UML, you’ll learn to discover and represent the details and scope of any design problem you choose to attack.
Database design is not an exact science. Many are surprised to find that problems with their databases are caused by poor design rather than by difficulties in using the database management software. Beginning Database Design, Second Edition helps you ask and answer important questions about your data so you can understand the problem you are trying to solve and create a pragmatic design capturing the essentials while leaving the door open for refinements and extension at a later stage. Solid database design principles and examples help demonstrate the consequences of simplifications and pragmatic decisions. The rationale is to try to keep a design simple, but allow room for development as situations change or resources permit.

  • Provides solid design principles by which to avoid pitfalls and support changing needs
  • Includes numerous examples of good and bad design decisions and their consequences
  • Shows a modern method for documenting design using the Unified Modeling Language

What you’ll learn

  • Avoid the most common pitfalls in database design.
  • Create clear use cases from project requirements.
  • Design a data model to support the use cases.
  • Apply generalization and specialization appropriately.
  • Secure future flexibility through a normalized design.
  • Ensure integrity through relationships, keys, and constraints.
  • Successfully implement your data model as a relational schema.
Who this book is for
Beginning Database Design, Second Edition is aimed at desktop power users, developers, database administrators, and others who are charged with caring for data and storing it in ways that preserve its meaning and integrity. Desktop users will appreciate the coverage of Excel as a plausible “database” for research systems and lab environments. Developers and database designers will find insight from the clear discussions of design approaches and their pitfalls and benefits. All readers will benefit from learning a modern notation for documenting designs that is based upon the widely used and accepted Universal Modeling Language.

 Database System Concepts, Sixth Edition
MG–H | English | 2010 | ISBN: 0073523321 | 1376 pages | PDF | 16 MB

Database System Concepts by Silberschatz, Korth and Sudarshan is now in its 6th edition and is one of the cornerstone texts of database education. It presents the fundamental concepts of database management in an intuitive manner geared toward allowing students to begin working with databases as quickly as possible.The text is designed for a first course in databases at the junior/senior undergraduate level or the first year graduate level. It also contains additional material that can be used as supplements or as introductory material for an advanced course. Because the authors present concepts as intuitive descriptions, a familiarity with basic  structures,  organization, and a high-level   are the only prerequisites. Important theoretical results are covered, but formal proofs are omitted. In place of proofs, figures and examples are used to suggest why a result is true.

 Metaclasses and Their Application: Data Model Tailoring and Database Integration

Publisher: Spr..in..ger 1995 | 210 Pages | ISBN: 3540600639 | PDF | 13 MB

Conventional object-oriented data models are closed: although they allow users to define application-specific classes, they usually come with a fixed set of modelling primitives. This constitutes a major problem, as different application domains, e.g. database integration or multimedia, need special support.

Using an extended metaclass concept, this book provides for the solution of this problem a simple but extendible open object-oriented data model, a so-called RISC model.
