Beginning Database Design Solutions
This book is intended for IT professionals and students who want to learn how to design, analyze, and understand databases. The material will benefit those who want a better high-level understanding of databases such as proposal managers, architects, project managers, and even customers. The material will also benefit those who will actually design, build, and work with databases such as database designers, database administrators, and programmers. In many projects, these roles overlap so the same person may be responsible for working on the proposal, managing part of the project, and designing and creating the database.
This book is aimed at IT professionals and students of all experience levels. It does not assume that you have any previous experience with databases or programs that use them. It doesn’t even assume that you have experience with computers. All you really need is a willingness and desire to learn.
This book explains database design. It tells how to plan a database’s structure so the database will be robust, resistant to errors, and flexible enough to accommodate a reasonable amount of future change. It explains how to discover database requirements, build data models to study data needs, and refine those models to improve the database’s effectiveness.
The book solidifies these concepts by working through a detailed example that designs a realistic database. Later chapters explain how to actually build databases using two common database products: Access 2007 and MySQL.
The book finishes by describing some of the topics you need to understand to keep a database running effectively such as database maintenance and security.
This book explains database design. It tells how to determine what should go in a database and how the database should be structured to give the best results.
This book does not focus on actually creating the database. The details of database construction are different for different database tools so, to remain as generally as useful as possible, this book doesn’t concentrate on any particular database system. You can apply the techniques described here equally to whatever database tool you use whether it’s Access, SQL Server, Oracle, MySQL, or some other database product.
Most database products include free editions that you can use for smaller projects. For example, SQL Server Express Edition, Oracle Express Edition, and MySQL Community Server are all free.
To remain database neutral, the book does not assume you are using a particular database so you don’t need any particular software or hardware. To work through the Exercises, all you really need is a pencil and some paper. You are welcome to type solutions into your computer if you like but you may actually find working with pencil and paper easier than using a graphical design tool to draw pictures, at least until you are comfortable with database design and are ready to pick a computerized design tool.
From the Back Cover
Beginning Database Design Solutions
Databases play a critical role in the business operations of most organizations; they’re the central repository for critical information on products, customers, suppliers, sales, and a host of other essential information. It’s no wonder that the majority of all business computing involves database applications.
With so much at stake, you’d expect most IT professionals would have a firm understanding of good database design. But in fact most learn through a painful process of trial and error, with predictably poor results.
This book provides readers with proven methods and tools for designing efficient, reliable, and secure databases. Author Rod Stephens explains how a database should be organized to ensure data integrity without sacrificing performance. He shares procedures for designing robust, flexible, and secure databases that provide a solid foundation for all of your database applications. The methods and techniques in this book can be applied to any database environment, including Oracle®, Microsoft Access®, SQL Server®, and MySQL®. You’ll learn the basics of good database design and ultimately discover how to design a real-world database.?
