Head First SQL

Anita Kuno writes "On a Sunday, a fellow user-group member suggested I learn SQL. The next day, an opportunity to review Head First SQL arrived in my email. Who was I to question? Prior to opening the couriered package, I had no knowledge of SQL, I knew databases were important, and I had seen the Head First website once or twice. Now, I can design and create databases, use mySQL databases, and understand questions and accompanying code posted to forums. The credit goes to Head First SQL's style, which introduces small bits of information, supported through multiple channels (such as photos with humorous dialogue, stick-men and stick-women, and input from critical personalities whose photos and input pop up throughout the book) regular tests and exercises so the new bit of data can find a home and settle into your memory. The regularly tested pieces of information are now in my brain so I don't have to look up the basic stuff." Read below for the rest of Anita's review. Head First SQL: A Brain-Friendly Guide author Lynn Beighley pages xxxv & 571 publisher O'Reilly Media, Inc. rating 9 reviewer Anita Kuno ISBN 0-596-52684-9 summary A beginners foundation for SQL

Head First SQL is about RDBMS (databases) specifically mySQL (version 5.0 or newer) and includes features of other databases. The book defines a database, demonstrates how to navigate an existing database, and teaches how to create simple and complex databases, as well as how to let a database grow from simple to complex.

Foundational understanding of database construction and navigation is the focus. The target audience is those brand-new to the topic as well as those with an acquaintance with the subject and the need for a greater conceptual understanding of databases.

It focuses on the basics of databases, so the main information should remain pertinent until RMDBS get re-conceived. I think revisions, such as the reprint due out in December, will add to the strength of the book as typos and coding errors will be addressed.

The title accurately describes the contents and the subtitle "A Brain-Friendly Guide" describes the goal of the approach. The only requirements for working with the material are: a computer or access to one, the ability to identify your operating system, familiarity with downloading from the internet (links and instructions are provided in the book and the program mySQL community release is free (download instructions are given for Mac and Windows users, I believe that instructions for Linux are not included with the assumption Linux users can access the mySQL community release page and download the program without a play-by-play)), and the courage to learn a command line window user interface if you don't already know this.

Head First SQL is most useful to those who, like myself, have heard passing references to databases and other than knowing they are important have no grasp of what it is, means, or can do. Also, this will be a helpful tool for those who have some of the verbiage, enough to pass at a cocktail party, but who would feel the cold chill of horror if expected to design, construct, and implement a database in conjunction with any of their paid responsibilities.

This is the first book that I have read on the subject of databases and the first computer book that I have been able to finish. So much of the educational information about program x, language y, or application z, depends on a working knowledge of the other two variables. This is a great book for beginners. It talks about data types, it explains null, and then has null explain himself. It tells me the importance of the semicolon at the end. All basic stuff. All stuff that other books take for granted. Many times when I believed I wasn't absorbing anything, along came questions I could answer, a crossword I could complete and match-column-A-with-column-B exercises that demonstrated that I was actually learning much more than than I was giving myself credit for.

It includes illustrations, photos, clean layout, and bite sized pieces of information. All this comes from the goal of allowing both sides of the brain access to the information. It's exactly the kind of approach that I need to reinforce the terms and concepts as well as provide encouraging feedback to keep me progressing through the material. I'm also grateful that it entertains me and keeps me going back to finish the whole thing long after the first blush of excitement has worn away.

Links, to the mySQL program necessary to work with the material, are included in the book as well as a few other links in the appendices. The Head First website is a must in order to link to the forums, newsletter, blog and downloadable files to create various tables used in the book. Head First came out with a web app called Hands On SQL which I would encourage you to try. It won't work with all of the book's material but it is a good-looking tool.

      You beat me to the post by by a couple of minutes. I agree that even advanced users can get good stuff out of the Head First books, but it is important to remember that the bad jokes, stock characters, and corny vignettes presented in the books are not there as part of some misguided attempt to be cute, but rather as a research proven cognitive aid for helping us, the readers, absorb the most information possible into our brains in the least amount of time with the minimum amount of re-reading, backtracking, and resorts to external commentaries.

      Note for GP: Understand what you are buying when you pick up a Head First book and why or else the wealth of useful information which they contain will be lost upon you simply because you cannot get past a pre-conceived notion about the presentation.

  2. who benifits? by techpawn · · Score: 3, Insightful

    This sounds like a good intro book but nothing of use to a seasoned DBA. It reads as though you gain basic knowledge of the subject of SQL and some basic mySQL syntax but the day-to-day operations of a database are probably not covered since those are very version specific and generally done with odd T-SQL statements or GUI interface.

    It sounds like a learn SQL in 24 hours book more than a SQL cookbook type resource, may be good for a developer who is starting out in the relational database world but I don't think DBAs will get much. At least, not from what the reviewer says.

    Database design and creation isn't something you pick up over 3 days. Sure, you can make something that works very quickly, but that doesn't mean it's a good design and isn't flawed. Designing a good database structure takes experience with the tradeoffs between full normalazation and added complexity, forseeing future needs, etc.

      IMHO Creating a database is one thing, Designing is another entirely!

      Making DDL scripts to run in the database is easy once you learn the syntax. Knowing their interaction with each other using Foreign keys, Indexes, and planning their future growth is a completely different set of skills that's only gained with experience with your data.

The question is generated because she's using a joining table to solve a many to many between her customer and address tables and has named the constraints herself the same on each table instead of letting the system generate them.

    As a database designer/developer who occasionally does DBA duties as well I initially found this quote terrifying in the extreme. But as long as this experimenting about is done on your own PC for at least the next few months, it's great that you're getting a start on a new (to you) class of software tools. Way too many people plough on using spreadsheets where they should be using at least Access. I encourage anyone with accountant or small business owning friends to pass on this review.

    Databases are a bit more than just queries. I find that most people new to databases start screwing up because thy don't understand that everything can't be stored as a varchar or that it's amazingly stupid to have every column in a table set as a key. Normalization is another big thing to knock into newbie database developer brains as well as naming conventions.

    Personally, I stand by 'Database Systems' by Connolly and Begg. Not simple, not for newbies but it coveres everything you need to know including doing ER diagrams for your structure... something every DB admin needs to do more of.

    IMO that sort of thinking is a mistake. It actually comes from the desire to cut down on planning time because management sees it as dead weight. And worse, people designing databases who have no clue what they are doing mathematically speaking.

    In general, I have found that every hour of planning time spent tends to eliminate up to 10 hours of coding, and often as much as 100 hours of pre- and post-release re-engineering and bug fixing.

    The goal ought to be to optimize time and expenses across the entire software lifecycle rather than cutting down on the most important places where time gets spent (on the design). This generally means spending more time on design, less on buzzword-compliance, and less on actual coding. If you do it right, testing and debugging effort go *down* as well.

    Instead people end up with bloated monstrosities when better-designed products could have been built with less time an money.
