Database Normalization Techniques - Essentials...

HOME | FORUM | NEWSLETTER | SITEMAP | ABOUT ME | CONTACT ME | ADVERTISE | WATERCOOLER Database Normalization explained. Topic Understanding and mastering database normalization techniques is essential in order to achieve a high performance database design for your system. If your design doesn't conform to (at least) the Third Normal Form (3NF), chances are high that you will find it hard to achieve the performance needed for a successful application. Furthermore, you will find that writing good DML-statements (SELECT, UPDATE, INSERT or DELETE) is difficult, and sometimes actually impossible, without using a lot of procedural coding (PL/SQL in Oracle, VB/C# in Microsoft products). Many "experts" will tell you that if you do database normalization up to (and including) the Third Normal Form, you're well off. The Database Normalization eBook shows you that this a far too easy approach, and it is richly documented with graphical Entity Relationship and Server Diagram examples. Before we proceed, may I ask what is your profession? (If no option matches you, just skip it): Teacher Student Systems Analyst/Programmer Software Project Manager Software Project managers: Learn to control how your database will meet all project requirements. Systems Analysts and Programmers: Learn how to build high-performing databases allowing clean DML statements that run FAST. Students and Teachers: Learn all there is about the most important database design techniques VERY FAST and in a way even your mother will understand. Students: Outsmart your teachers. The Five Normal Forms The Database Normalization eBook will walk you through all the 5 Normal Forms in database normalization normally used to analyze data models in the making. We will be starting with formal definitions, and then explore and explain them in plain language. The mission of this 50-page eBook is not to deliver academic definitions of the normal forms, but to communicate the author's practical experience in data modeling using database normalization techniques, built on nearly 30 years of business experience with data modeling for government, industrial, communications and other large relational database customers. The Database Normalization eBook also contains separate chapters on Boyce/Codd Normal Form (BCNF), and Domain Key Normal Form (DKNF). Database Normalization eBook: Table Of Contents "Your eBook is now mandatory reading for my project members." Sabrina, Project Manager, Germany Target audiences: Software project managers Understand the difference and importance of database analysis and design vs. programming Reveal why programmers decide differently than the business needs, and why it can create a disaster Get on even terms with the technologists with no-fuzz language Speed up the design process Cut down on time and money spent You pull the shots Why all the talk about performance considerations is non-essential Compressed information, takes less time to learn and apply Easy, down-to-earth graphic examples Conceptual modeling examples (ER diagrams) Logical modeling examples(Server diagrams) Create functionality-rich structures with maximum business flexibility Design for business scalability All within budget and time! "I'm myself (since 1996) in the data modeling business (OLTP and OLAP, with accent on OLAP for the past 5 year).I own and have read about 30 - 40 books on this topic (practically most of the available and out of print books) and I'm still impressed by your website and ebooks. I like a lot of things about the keynotes and ebooks, what I like most is the balance you have managed to keep between a dry subject / theory and a clear "down-to-earth" treatment of the subject, without sacrificing any of the important aspects. The examples in the normalisation ebook are also very good." Georg Breazu, Senior Systems Consultant, Germany System analysts and programmers Compare normalized and denormalized structures Experience consequences of poor design on your programs Why the business model is more important than easy programming Complete DDL scripts so you can experiment with database tables Avoid poor-performing databases and programs Speed up the development process and avoid unneccesary time and cost spendings Highten the quality of the database as well as your SW Understand why poor normalization can make it impossible to write some DML-statements against the database "I've seen good, bad and butt ugly database design books. The database normalisation eBook is in the category of good. It is a concise guide, based on scientific principles and common sense." Philip, Systems Analyst, United Kingdom Students and teachers Explain database normalization in understandable (read: plain English) terms Ready-made examples for direct use Play with the ready-made database structures See consequences all the way from conceptual modeling to physical database structures Shorten down time to understand and master the 5 Normal Forms Instant download: Get going
