IBM Sets DB2 Database Free (Beer)

Anonymous Coward writes to tell us that in the hopes of winning more developer interest, IBM has released a free version of their DB2 database. From the article: "DB Express-C is the same database as IBM's commercial offerings but the company places limits on what kind of hardware it can run on. It can be deployed on systems with two processor cores or up to two dual-core chips on Advanced Micro Devices- or Intel-based servers. The memory limit is 4GB but there are no limits on the size of database or number of users. "

      I'm glad you brought up performance versus scalability. PostgreSQL is often considered slow by MySQL fans who fail to understand the concept of scalability. Simply stated, MySQL is typically faster than PostgreSQL with low scalability requirements yet PostgreSQL tends to scale much, much better than does MySQL for both complex queries and highly concurrent, mixed operation loads. Obviously, this is a rule of thumb and not a hard/fast rule. I'm sure there are corner cases (which is often put forward in MySQL benchmarks, which are not reflective of real world applications) in each camp which ignore the rule.

      For people that do not understand scalability versus performance, let's put it like this:
      MySQL is fast for one user and PostgreSQL, while fast for one user, tends to be slightly slower than MySQL. On the other hand, add a hundred concurrent, mixed operation (aka, not read only) users and MySQL tends to go belly up. At the same time, given the same example, PostgreSQL is happily chugging along; albiet at increased latencies. Of course, this statement is broad and makes many assumptions, but it will hopefully help others understand the concept.

      So, given your rankings above, PostgreSQL, tends to find a middle ground between Oracle's performance/scalability ranking. In other words, PostgreSQL tends to scale less than Oracle yet tends to perform better. MySQL, on the other hand, performs fairly fast for read-only databases but scales very poorly.

      While I agree with your definitions of scaleability & performance, what would lead you to the above conclusion?

      Both postgresql and mysql lack query parallelism, fine memory tuning, any kind of partitioning, etc. Without these features postgresql is *at best* only faster than oracle on index-oriented extremely transactional applications. And I'd say it was pretty safe bet that Oracle would stomp postgresql in that space as well on reasonable hardware (ie, not desktops, etc).

      Note, of the two databases I would still rather work with postgresql - it's a fine product and allows me to avoid dealing with oracle personnel. It's just not as fast.

      > MySQL, on the other hand, performs fairly fast for read-only databases but scales very poorly.

      Scaleability should also consider economics, and mysql can cost. It all depends on how you use it. At what? $500/year/database it can easily be more expensive than a small oracle/db2/etc database (which after the first year will drop to 18% or so maintenance). Given that cost postgresql could pull ahead - even assuming equal performance.

      And compared to db2 or oracle, then for the classic read-only applications (reporting) mysql will fall *far* behind. Again, the lack of parallelism & partitioning can easily lead to a 40x difference in performance between db2 & mysql. And while hardware costs are dropping, they aren't dropping so far that you want to spend 40x as much on a server in order to support mysql.

So where somebody like Microsoft has to limit the specs on the free version pretty severely, because otherwise they won't have a retail product to sell, IBM knows that a lot of people want to run their database on big iron. And big iron is a lot of money, not just in the hardware, but also in the service contracts and stuff that go along with it.

      If your database is mostly used on commodity, low-end hardware, you can't give away a version that runs on a quad-core, 4GB machine: that's eating into your home market. IBM can, because a lot of their revenue (I'm guessing) comes from machines much further up the specification ladder than that. In fact, they would love you to run DB/2 on a high end machine, because the sooner you do, the sooner you'll make use of it, and probably the sooner you'll find its limits. (Following the general rule that software expands to fill whatever resources you allocate to it.) And when you hit the limits of the commodity/low-end hardware, IBM would be more than happy to help you migrate your DB/2 install into something a little sweeter. For a price, naturally.

    DB2's XML functionality looks awesome, I'm definitely going to try this out.

    I am interested in all of these free editions for my web projects because it seems like it offers simpler scalability than MySQL down the road. Most high-end web developers--which I certainly am not--often end up having to find ways to get off of MySql as the site grows. Am I the only one who likes the idea of these scalable databases that I can buy later on?

    On the other hand, if you're on Windows, it seems like MSSQL 2005 is your clear choice. It surprises me that any of these companies are bothering to compete against Microsoft there. It's beautifully integrated into the Visual Studio IDE, as well as offers .NET-compiled stored procedures and other Windows-centric friendliness. Oracle and IBM have to come up with great linux tools to compete against what Microsoft has created in MSSQL 2005 (Oracle's Raptor is a start)

    If you are a GPL or death person then there is not reason. I would rather us Postgres than MySQL but that is just me.
    If MySQL works for you and you don't need anything else and don't want to learn anything keep MySQL.
    Now for the reason you would.
    Want to learn how to use DB2?
    Want a really heavy duty ACID compliant Database server?
    The limits on DB2 are... TINY I mean even in a good sized company a 4 gig ram limit and two core limit is unlikely to cause you issues.

    This is to target MS-SQL not MySQL. If you develop for MS-SQL you are not only locked into MS-SQL but also Windows. DB2 Runs on everything under the sun including all the big iron IBM sells.
    Good move for IBM. I may even install it to take a look. I will probably stick with Postgres since IBM could always make it not so free in the future. But if I ever did need to scale it one of my projects to Enterprise size, DB2 is a good option.

    For example: I'd heard good things about ASP.NET 2.0. I've been a Java guy for a couple years, but decided to try it out on a new project. I got the VWD package for free, and got going. After a couple weeks I realized that this was the direction I wanted to take with future development and got my boss to order up some Visual Studio Pro licenses for myself and coworkers.

    I started in Java because it was free, and would still be there had it not been for VWD. I think this is an excellent strategy by IBM.

    IBM stopped selling their OS/2 operating system last year but has refused to release it as open source or even to allow 'free' licenses for additional users. If IBM cannot find the generosity to release a 'free' version of a defunct operating system which there are cash-paying former customers who could actually benefit, there's reason to be suspicious of a 'free' version of DB2. The DB2 free version is probably some sort of scheme for getting lock-in to the platform and is not just an example of generosity by IBM.

    IBM does not do much with SMEs. But some SMEs will become large enterprises, and when they do they will want big tin and support and they will want to keep on using what they've got.

    The logic is exemplary. Microsoft has a lot of SME installations of MSSQL, and they hope that some will become big installations and by then they will have figured out how to do big iron. So IBM says to the SME "come to us instead and no matter how fast you grow your investment in software will never be obsolete. Hey, worried about viruses and licensing and stuff? Want to start off from day one with Linux on the server and the desktop? We can do that for you."

    The reasoning is sufficient to have caused me to download DB2 for Linux to install on Ubuntu tomorrow morning, if only to evaluate just how difficult a port will be for us.

    I'm certainly not complaining after hearing this bit of news. I've used to working with MySQL and PostgreSQL and have done a few things with Oracle too over the few years I've been developing apps. I can't say I have a preference though. I used pick the DBMS depending on the requirements of the app, rather than by my preference. My current employer, however, uses DB2 for all projects, and so far I've been quite taken with the scalability. Stress testing now makes me smile when it used to make me want to hide somewhere very, very dark and far away (That is vs. MySQL and Postgre).

    The thing that has bugged me however, is that the licences are so expensive. This now means though, that I can run my own instances of the db for development and early release stuff and don't have to be bugging the DBAs for every minor detail, only when I need their expertise. Nice. Boosts my productivity.

    And I do have a few personal projects going that I hope will someday be needing the scale I can get out of DB2. Now I can develop them and run them on DB2 from the start.
