Sharing Knowledge of
Highly Efficient Database Design

Do You find it hard to design and maintain high-performing relational
databases?

Welcome to The Database Design Resource Center!

This website discusses, or rather, talks with you, in an easy way, on
themes regarding database modeling, normalization techniques, primary
key considerations, programming strategies, DBA problems (and
solutions), and many other issues relating to building database models
that will form the basis of your high-performing databases.

The purpose of this site

If you are in the process of considering, starting up or already have a
database design in place and running, by examining this site you will
find an abundance of advice on how to improve your design in order to
create high-volume, fast-performing databases:

Modeling the Universe

Entity Relationship Model of the Universe-

This is just a play with Entity Relationship Modeling: Placing the
Universe into one single diagram :-).

Actually, I wrote it to show you the power of ER modeling, as well as
to give you a head-start on the subject...
* The Database Design Forum: A place to interact with fellow DB
design people (including the Webmaster; yours truly)
* Conceptual modeling (ER diagrams)
* Analysis and logical modeling (Server diagrams)
* Physical model transformation from logical modeling
* Choosing solid primary keys
* How primary keys become foreign keys
* What is normalization (In plain English!)
* What's all the fuzz about denormalization, anyway?
* Various Oracle constraints, and what they really are
* Project organization
* DBA issues in Oracle and SQL Server
* Installation issues in Oracle and SQL Server
* Taking care of customers

and much more...

Focused, free DB information and low-cost eBooks

Far too often, you have to buy expensive books, or attend high-cost
courses, to keep ahead in this business. I aim to change that, and
create high-end, valuable articles and eBooks on specific topics, so
that you can keep yourself at the edge of knowledge in your business. I
believe, that using free keynotes and free/affordable eBooks from this
website, you will be updated and in the front of your colleagues in
your field of work.

Currently, the following eBooks are available:

The Entity Relationship eBook is a free gift for subscribers to my
newsletter.

The Normalization eBook is directed at people who want to educate
themselves in refined datase design skills: Being knowledgable about
subtle themes only a skilled Systems Analyst would be aware of...

Visit my eBooks page, which always contains my eBooks as they are
published.

Talking straight

I have set out to do this because there is so much confusion in our
field of work; lots of articles on the net, or in books, pretend to be
"scientific", using words and language which is difficult to grasp,
even if the database design work should be intuitive and natural. The
database community has to learn how to talk, and not least, communicate
with our customers in an understandable manner.

My eBooks and my website are made to do just that, and I hope you will
read them with a learning mind.

A site for Database people

This site is made for database professionals seeking fast and reliable
support and inspiration for solving time- and performance-critical
issues in their database jobs. Since you have arrived here, you most
likely have a genuine interest in improving your knowledge in the
database design field. This site is alive and listening to you, my
visitor: After all, this site is built for you! Subscribe to my
newsletter and stay informed.

Products

The Database Design Resource Center (me) is producing a series of
eBooks, investigating and describing the various activities included in
bringing up high-performing, normalized relational databases. These
will apply whether you are using Oracle, MySQL, Access, SQL Server or
any other database that is (or pretends to be) "relational".

Other resources

At The Database Design Resource Center I also work on presenting
articles of general interest related to analysis and design of
relational databases; effective design patterns for you to use as an
inspiration and support for your day-to-day work, as well as I
investigate the vast amount of litterature on the subjects, that is
being offered from different sources.

I will try to provide you with best-of-choice, critically selected
software and methods literature based on my own experience and
recommended readings.

Sharing knowledge

As mentioned above, I keep this site to help people understand how to
design their databases for maximum performance and stability. Sharing
information is, after all, the real good use of the Internet. Please
let me know if anything on this site is misleading, needs updating or
additions. Use the Contact me form to reach me.

"The most important motive for study at school, at the university, and
in life, is the pleasure of working and thereby obtaining results which
will serve the community.
The most important task for our educators is to awaken and encourage
these psychological forces in a young man or woman.
Such a basis alone can lead to the joy of possessing one of the most
precious assets in the world -
Knowledge or artistic skill."
Albert Einstein

Enter your search keyword(s) and the keyword "zorgium" into the search input field of http://bing.com, http://yahoo.com or http://google.com.

Heads up: There's an ongoing spamdexing of Google searchbot algorithms. Sites that are 'copies of copies' and cloaked sites which include Zorgium keywords presented to search engine crawlers yet garbage content presented to human visitors were hosted on thousands of IP addresses and domains registered immediately after the introduction of Zorgium in November of 2009. The Hostgator/'The Planet'/Softlayer datacenters in Texas seem to be the epicenter of this activity in conjunction with anonymously registered domains of various TLD's but primarily .info domains at Godaddy which, in our opinion, has some sort of connection to the domains of goldmint.in and goldmint.org. Google has begun to notice this and has begun to lower the ranking of these sites and put our original sites back on top of the search rankings. These actions, as far as we can tell, negatively impact the use of the keyword 'zorgium' as a search term and provided little benefit, if any, to the perpetrators.
