Database Design for Mere Mortals: A Hands-on Guide to Relational Database Design, Second Edition lets us know from the off that programmers and software architects don't really make a conscious decision to design an application (particularly one with online exposure) around the three-tier model-view-controller design pattern anymore. Three-tier, largely because of its adaptability and stability, is the norm. All of which means you need a database to underpin each of your applications. Designing your databases correctly can make the difference between slow-running, complicated code and software that's speedy, modular and easy to work with. Database Design for Mere Mortals prepares someone with only a passing familiarity with databases for the important job of building the persistence layer (also called the data model) for software.
Michael Hernandez explains database design in tradesman's terms. That is, he shows his readers how to identify the business problems that have to be satisfied by a database, then proceeds to explain how to build a solid solution to them. Hernandez's approach combines procedural guidelines (first identify critical facts, then apply a certain logic to yield tables, then establish cross-references, and so on) with practical definitions that clear up much of the rich trove of jargon surrounding databases. He walks through numerous examples, and doesn't shy away from the complexities that always exist in real customers' requirements. If you're not familiar with database design, and want to be, this is the book you need.
Topics covered: how to design databases that fit business requirements and make software construction easier. In addition to explaining relational database concepts, the author explains data integrity, null values, keys, table relationships (one-to-one, one-to-many, and many-to-many) and data types. He emphasises processes designers should follow in building a new database or improving an existing one. --David Wall, Amazon.com

Relational databases are powerful tools for organizing data, but learning to use them effectively can be painful. Relational Database Design for Mere Mortals explains the concepts of relational-database design in an easy-to-digest fashion that covers both the theoretical underpinnings and their practical implications. Hernandez covers all the basics--table and field structure, keys, relationships, business rules, and more--but always keeps his feet on the ground with advice for real-world implementations and a particularly strong section on analyzing your current database infrastructure.

Ignore the Soreheads -- A Great Book,

Rezension bezieht sich auf: Database Design for Mere Mortals: A Hands-On Guide to Relational Database Design (Taschenbuch)
No, this is not the book for you if you have extensive experience in software design and have already absorbed the basic concepts of database design by osmosis.This is a book for "mere mortals," just like it says. I'm a reasonably smart, reasonably well-educated person who had some computer experience, but didn't even really know what a relational database was. Through circumstances too odd to mention, I was given primary responsibility for designing a commercial web application. I read this book cover to cover, and designed the database that became the core of the product. The product actually works, and seems to be selling. Later in the development cycle, I worked with a brilliant MIT-trained software engineer, and he found my basic db design just ducky. I definitely owe Mr. Hernandez a beer. Figured writing this review was a reasonable substitute. Helfen Sie anderen Kunden bei der Suche nach den hilfreichsten Rezensionen

Practical and dogmatic, just like database should be...,

Rezension bezieht sich auf: Database Design for Mere Mortals: A Hands-On Guide to Relational Database Design (Taschenbuch)
This is the BEST book there is for learning about DB design from the ground up. It moves very quickly from theory to how to practically implement a robust DB design. It assumes no knowledge, but by the end of the book you WILL be able to sit in discussions with MIS and understand and contribute to the discussion. I don't want to leave the impression, however, that this skips the hard topics: far from it. It covers Business Rules and even has some excellent forms that you can copy from the book and use in your information-gathering sessions.Bottom Line: Get this book and get the big picture, then get the specialized book for your DBMS.

How to organize data in databases made simple!,
Von John Leo Mencias (Belize) - Alle meine Rezensionen ansehen
Rezension bezieht sich auf: Database Design for Mere Mortals: A Hands-On Guide to Relational Database Design (Taschenbuch)
Designing a simple database, especially one that does not need to store transaction-related data, is supposed to be a straightforward process. And this book affirms this fact. Starting from a real-world situation (though somewhat oversimplified), the author takes you through a series of clearly-defined and practical steps to finish with a robust and well-designed database: ready for setting up in anyone of the more popular DBMS programs. Well, almost... The author does not discuss or even mention other design parameters, such as access mechanisms and indexes, that should be set in order to tune the database for speed and efficiency. You'll need to consult a higher-level text such as 'Handbook of Relational Database Design' by Fleming et al for this and more in-depth stuff.This book serves as a complete, stand-alone tutorial if all you want to do is set up a simple database, and where the emphasis is on how the data should be best organized to fulfill any request for information that is based on the data. Otherwise, it is a solid introductory text or even a refresher that should make you excited about databases and the irreplaceable role they play in a world where 'information the way you want it' is king!
