IBM To Purchase Informix Database
Boban Acimovic writes "According to this story on the Yahoo Financial News", IBM is going to buy Informix Database Software for $1 billion in cash. The main players in database leader struggle will be Oracle and IBM after this acquisition." That's in the commericial space - obviously SleepyCat, PostGres and MySQL and others aren't going away. And it appears that the other parts of Informix will be staying around as a seperate biz, so we should continue to see their support for OSS [?] . -
Microsoft Access As A Client For Free Databases?
Daniel Dvorkin asks: "A few months ago, the small but growing company I work for decided that our current FileMaker-based database solution wasn't working. As DBA, I recommended a MySQL server with a Perl or PHP-based front end. My boss, who despite being a Mac guy has recently developed an inexplicable mania for all things Microsoft, is insisting that I develop everything with Access as a front end. I'm deeply unhappy about this, but I'm hoping that I might be able to salvage a little bit of the situation by using MySQL on Linux rather than SQL Server on NT for the back end." Think something like this might be possible? Read on for more informaiton. Updated!"Can this be done effectively? Is there any good documentation on connecting Access to Non-Microsoft DB servers in general, and MySQL in particular? No 'ODBC RTFM' flames, please; I'm looking for something a little deeper here."
I'm not very familiar with ODBC beyond it's basic use, so I really can't answer this question, but might this be possible if the MySQL server were somehow treated as an ODBC source? It would be tremendous coup if somehow the power of the Access front end could be used with MySQL (or PostgreSQL, or mSQL or any other open sourced RDBMS)? MySQL does have some ODBC functionality and as well as other ODBC related links on their site.
For those of you who want to immediately play around and see if this is possible, you can find the MySQL ODBC driver, here and a PostgreSQL ODBC driver here.

MySQL 3.23 Declared Stable
redcoat writes "After two long years, MySQL 3.23 has been declared stable. Improvements over 3.22 and .21 include rudimentary transaction support using the BerkeleyDB lib, full-on replication (master/slave configuration) and lots of other goodies. It's been a long wait, but a worthwhile one, no doubt." -
A Little Bit Of BBS Nostalgia
Ron Harwood writes: "I was getting nostalgic for the BBS door games of the late 80's and early 90's -- and decided that some of these could quite easily be brought onto the Web. So, with help from some of the players, I've created a Web version of the old BBS game TradeWars -- and released it as open source. You can try it out at BlackNova.net or download the source for your self at SourceForge. It's made with PHP and MySQL and it's getting reasonably bug free. :)" -
Open Source Databases Revisited
pusakat writes "If you've been following performance comparisons of the different Open Source databases, Tim Perdue revisits PostgreSQL v. MySQL with production data from SourceForge and comes up with interesting results. This may be fodder for yet another 'my database is better than your database' exchange from both camps but the results are interesting anyway." -
MYSQL & Row Level Locking
An anonymous reader noted a press release talking about how NuSphere is planning on adding row level locking to a version of MySQL due out 1Q 2001. Anyone who's used MySQL for anything with more then a few hundred thousand records (like, say, Slashdot to pick an arbitrary example) knows that this is the biggest shortcoming MySQL has... you can work around replication and transactions, but when your whole DB freezes because of one piddley write, its more then just a little annoying. -
Migrating From MS/IIS to Linux/Apache?
Mixhaus asks: "I'm trying to promote the Linux culture in my company. I want to migrate or at least start all new web projects on a Linux/Apache setup. Currently all the development is done on IIS/ASP with MSSQL 7.0. Has anybody done this kind of migration before? Any suggestions?""These are some of the questions that come up to my mind:
- Be able to migrate IIS to Apache first, and still be able to access the MSSQL databases (FreeTDS?)
- Use a scripting syntax similar to ASP so that the programmers don't have much of a headache learning new stuff (PHP looks like a solution).
- Migrate MSSQL 7 to MySQL, PostgreSQL or other (Which one is better for web development?)
- Web log reports (I need to generate reports on the web site usage. What weblog report generators are available for Linux? Which ones do you use? Are there any that generate graphs, charts, etc..?)

MySQL 3.20.32a Released Under GPL
Rolan writes "It seems that MySQL has been released under the GPL. Though I can't find any stories on it, you can see the 'news' here." We're posting this because lots of people have sent it in, but don't get too excited about it, okay? According to this Linux Today piece sent in by bradsjm, only one older version of MySQL is being released under GPL. A good start, and worthy of applause, but not that big a deal in the overall scheme of things. -

Review: MySQL and mSQL
Thanks to both danimal and Doc Technical for reviews of the latest and greatest O'Reilly book, Randy Jay Yarger, George Reese, and Tim King's MySQL and mSQL. An excellent book for those who are looking to do database development (and MySQL powers Slashdot!), click below for more details. MySQL & mSQL author Randy Jay Yarger, George Reese, and Tim King pages 506 publisher O'Reilly rating 8.5/10 reviewer Dan Weeks & DocTechnical ISBN summary A good introduction to the world of relational databases and an excellent reference for MySQLand mSQL. First Review: Doc TechnicalThis is certainly one of the more orthogonal books I've read of late. Besides the obvious axis of MySQL and mSQL, the book also covers the implementation of these databases on Unix, Windows 95 and Windows NT. And it covers a wide variety of programming languages, including perl, Python, PHP, Java, C, and C++.
While this is certainly a good book, in fact a very good book, this wide coverage means that the average reader may need to skip around a bit to get to the parts of the book they need. A Linux perl mSQL programmer will necessarily take a different path through the book then, say, a Windows NT mySQL database administrator.
Not that straying down the wrong path is always a bad thing. It was interesting to read about the quirky differences between different OS implementations.
"Windows 95 leaks about 200 bytes of main memory for each thread creation." [page 41]
"...[D]atabase and table names are case-sensitive under Unix and case-insensitive under Win32." [page 43]
The book is divided into three broad sections: "Getting Started with MySQL and mSQL", "Database Programming", and a final "Reference" section which spans fully half the book. O'Reilly's high standards for editing, layout, writing, and clarity are all evident throughout.
What I Liked Best For MySQL users, this book may appear to present a bit of a quandary. MySQL already comes with a 400+ page reference manual, and a quite nice one at that. But actually, the O'Reilly book covers much material the manual doesn't.Chapter 2 covers relational database design, and serves as an excellent introduction for the uninitiated. Some college texts could learn a lesson on clarity from the authors' explanation of normal forms.
Chapter 6 has an interesting, short history of the development of SQL.
Chapter 7 describes some of the other free SQLs available, and also provides some insight into those features that MySQL/mSQL don't provide: things like stored procedures, triggers, transactions, and subselects. This chapter is useful for people trying to decide which SQL engine they need. If your sitting on the fence, trying to decide on MySQL/mSQL versus a commercial SQL offering, this chapter may help you decide.
The book's cover declares "Databases for Moderate-Sized Organizations & Web Sites", and the book delivers on this promise by including web-oriented sections on general CGI programming, Perl, and PHP.
The second half of the book provides a good reference to the MySQL/mSQL API's for several languages, as well as the MySQL/mSQL utilities, and a good reference for SQL itself. Most of this information is available elsewhere, and in more detail, but it's useful seeing the various language APIs presented side-by-side, particularly if you're not sure what language you might want to use. I've been contemplating Python programming for a while, and the simplicity of its MySQL API is certainly seductive.
What's Missing It's hard to find fault with the material included in the book, but I was surprised by some of the things that were left out.There really is no ground-zero, simple mySQL/mSQL tutorial. For people beginning with a new SQL engine, it would be helpful to have a chapter that holds their hand, showing them how to create a database, then create a simple table, the insert records into the table, using the mysql utility. Tutorials are available for MySQL on the net (see www.mysql.com) and one is provided in the MySQL Reference Manual.
The book covers programming using a wide range of languages, but arguably one of the most popular languages, C, seems to get comparitively little coverage. There are only about six pages devoted to C programming, and one of those is a list of API functions. I would have welcomed more. [Admittedly, there is more on C in the book's Reference section, but this covers individual API calls, and doesn't provide any longer examples.]
There were a few rare cases in the book where I disagreed with the authors, or at least thought they needed to add a bit of additional amplification. On page 109, they state that:
"If you know that a lot of clients will be asking for the same summary information often... just create a new table containing that information and keep it up to date as the original table changes."
I have a bit of a nit to pick with this, as seven pages later they discuss the lack of a feature called triggers that would greatly simplify keeping a summary table in sync. Without a trigger, you'll have to devise your own method for keeping a summary table in step with the original table, which may be non-trivial depending on how often the original table changes and how often the summary table is accessed.
Summary This book tries to cover a lot of ground, and so it necessarily hits turf that some subset of readers won't care about.For the seasoned MySQL programmer or database administrator, this book is a fine companion to the Reference Manual. With its clear introduction to SQL and relational database design, it also makes a good introduction to new SQL users in general.
Second Review - Dan Weeks
The Scenario There comes a time in every project when storing and retrieving data from flat files or proprietary formats (i.e., MS Excel) is no longer feasible. A Relational Database Management System (RDBMS) would be great, but Oracle, Sybase, and Informix can't be justified because of the cost. Along comes MySQL and mSQL, two of many freely available Database Management Systems. While neither of these DBMS's are as full featured and robust as their more mature brethren, they can definitely hold their own in the world of databases. For small and medium sized organizations and web sites either of these DBMS's can provide a sufficient level of functionality and flexibility to store and retrieve your data. What's Bad? The only shortfall I could find is the lack of references to other, more advanced books on the subject of database design and normalization (although that probably doesn't fit in with the publishers motives, but it would be nice). The book is well rounded and all of the authors are very knowledgeable and well written. What's Good? The first thing that struck me as absolutely wonderful about this book is the structure. By breaking the book into three sections the authors have allowed for many different database users to find this book valuable. Getting Started with MySQL and mSQL The first section, Getting Started with MySQL and mSQL has everything the novice needs to at least get one of the packages up and running so that they can experiment with a database system. The authors do a great job of making sure that the reader can skip sections if they don't pertain to them. Introductory topics like What is a Database? and History of MySQL are essential in making sure the subject matter is well rounded and accessible to everyone (especially to people like myself that did not take database classes at university). Later chapters explain and detail database design and normalization in a manner that is easy to understand so that the first databases you build won't suffer from repetition and data inconsistencies. The authors also do a good job of explaining SQL and specifically the variants that MySQL and mSQL use.One of the high notes is the single chapter, Other Mid-Range Database Engines. Not only do the authors recognize that there are other database engines out there, they also point out what features MySQL and mSQL lack.
Making it Go The second section of the book, Database Programming, is a well written set of chapters that start off with the architecture of databases and client-server application and how they relate to data processing. The authors then quickly take you into the guts of interfacing with the database. They cover CGI, Perl, Python, PHP and other embedded HTML styles, C/C++, and Java. While I have only ever used Perl, Python, and C to interface to a database I can say that the chapters on the other API's seem to do just as good a job and at least allowed me to understand (if even in the most simple of terms) how those languages function in relation to your database engine of choice.We all love our nutshell books, especially the XXX In A Nutshell series because they are great references. The foresight of the authors is incredibly prevalent in the third section, Reference. The authors actually took the time to make a ...In A Nutshell type of reference and then stick it into the book. Reference chapters that i have found invaluable so far are SQL (which includes separate sections for MySQL and mSQL's variations), and MySQL and mSQL System Variables. Other sections include C, PHP and Lite, Python, Perl, JDBC, and programs and utilities associated with MySQL and mSQL.
So What's In It For Me? If you are at all interested in database programming or you run a database at a small- to mid-sized organization or web site then this book is a must have. For those people that are in need of a little instruction on database design and normalization this book would be a good start. If you have been working with either MySQL or mSQL for a while then this book may be a bit basic for you, but the reference chapters will more than make up for the cost of the book.Purchase this book at Amazon.com

MySQL author gives view on Patents
Michael Widenius, the main code-contributor to MySQL says that that software patents are bad for the community, should not be awarded for software ideas, user interfaces, standards or interoperability. Moreover if a patent were to be awarded, it should only be for major work (something that can't be done by a single individual within 50 years) and last 2-3 years at most. -
