  • This paper discusses the structure and components of databases for real-world e-commerce systems. We first present an integrated 8-process value chain needed by the e-commerce system and its associated data in each stage of the value chain. We then discuss logical components of a typical e-commerce database system. Finally, we illustrate a detailed design of an e-commerce transaction processing system and comment on a few design considerations specific to e-commerce database systems, such as the primary key, foreign key, outer join, use of weak entity, and schema partition.

  • 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.

  • Everyone keeps data. Big organizations spend millions to look after their payroll, customer, and transaction data. The penalties for getting it wrong are severe: businesses may collapse, shareholders and customers lose money, and for many organizations (airlines, health boards, energy companies), it is not exaggerating to say that even personal safety may be put at risk. And then there are the lawsuits. The problems in successfully designing, installing, and maintaining such large databases are the subject of numerous books on data management and software engineering.

  • 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....

  • NLFE to databases have failed in a commercial context, largely because of two reasons. Current approaches to the management of ambiguity by relying on inference over a world model create ungoing customisation requirements. Furthermore the design of NLFEs is subject to constraints which research in CL/ NLP does not address. In particular, standard parsing techniques (including "robust" ones) require complete lexica and cannot be deployed because new data would create a constant need for dictionary update.
