  • Learn effective and scalable database design techniques in a SQL Server environment. Pro SQL Server 2012 Relational Database Design and Implementation covers everything from design logic that business users will understand, all the way to the physical implementation of design in a SQL Server database. Grounded in best practices and a solid understanding of the underlying theory, Louis Davidson shows how to “get it right” in SQL Server database design and lay a solid groundwork for the future use of valuable business data....

  • Chapter 7 discusses how to design a relational database schema based on a conceptual schema design. This chapter presented a high-level view of the database design process, and in this chapter we focus on the logical database design or data model mapping step of database design. We present the procedures to create a relational schema from an Entity-Relationship (ER) or an Enhanced ER (EER) schema.

  • Relation Decomposition and Insufficiency of Normal Forms (cont.): Attribute preservation condition: Each attribute in R will appear in at least one relation schema Ri in the decomposition so that no attributes are “lost”. Another goal of decomposition is to have each individual relation Ri in the decomposition D be in BCNF or 3NF. Additional properties of decomposition are needed to prevent from generating spurious tuples

  • Appendix B - Advanced relational database design, first covers the theory of multivalued dependencies; recall that multivalued dependencies were introduced in Chapter 8. The project-join normal form, which is based on a type of constraint called join dependency is presented next; join dependencies are a generalization of multivalued dependencies. The chapter concludes with another normal form called the domain-key normal form.

  • Chapter 8 - Relational database design. This chapter introduces the theory of relational database design. The theory of functional dependencies and normalization is covered, with emphasis on the motivation and intuitive understanding of each normal form. This chapter begins with an overview of relational design and relies on an intuitive understanding of logical implication of functional dependencies.

  • Before you build your tables, you design your database. In this lesson, you examine the data modeling process and relational database concepts, and define normalization. You also translate an entity relationship model into a relational database design. At the end of this lesson, you should be able to  Describe the stages of system development.  List and define basic types of data relationships.  Define a relational database and its components.  Read an entity relationship model.  Translate an entity relationship model into a relational database design....

  • I often ask myself, “Why do I do this? Why am I writing another edition of this book? Is it worth it? Isn’t there anything else that I could be doing that would be more beneficial to me, my family, or the human race? Well, of course there is. The fact is, however, I generally love relational databases, I love to write, and I want to help other people get better at what they do. When I was first getting started designing databases, I learned from a few great mentors, but as I wanted to progress, I started looking for material on database design, and...

  • This is the exercise book to accompany the present author's An Introduction to Relational Database Theory. With two exceptions, these exercises are copies of those given at the ends of Chapters 1-7 of that book. The exercises using Rel given with some of those chapters are also included. The first exception is Exercise 7 for Chapter 7, which I have replaced by a precise, detailed specification for a comprehensive database design. The second is a set of additional exercises using Rel, exploring virtual relvars and user-defined type definitions....

  • This book introduces you to the theory of relational databases, focusing on the application of that theory to the design of computer languages that properly embrace it. The book is intended for those studying relational databases as part of a degree course in Information Technology (IT). Relational database theory, originally proposed by Edgar F. Codd in 1969, is a topic in Computer Science. Codd’s seminal paper (1970) was entitled A Relational Model of Data for Large Shared Data Banks (reference [5] in Appendix B)....

  • Chapter 6 - Relational database design: Converting conceptual models to relational databases. The primary objective of this chapter is to describe a procedure for converting a conceptual business process level REA model into a logical relational database model and then into a physical Microsoft Access database implementation. This process involves a relatively straightforward set of rules that could even be programmed as an algorithm so that a computer could accomplish the conversion. This chapter also discusses data entry issues.
