      Hey, I like Java as much as anyone, but if you're looking for a fast, multi-platform, zero-administration database be sure to check out SQL Anywhere Studio []. The Developer Edition is completely free and runs on Linux, Solaris, Mac OS X, Netware and most flavors of Windows, including CE/PocketPC. See the description of what's in SQL Anywhere Studio [] for details. (Note that some of you may remember SQL Anywhere as Watcom SQL.)

        Your post was certainly informative in that others might have learned about a new tool and are looking at Sql Anywhere, but to be fair, the purpose of that tool is different than Cloudscape's.

        Embedding a database in an application can be very useful, such as in a desktop GUI where you cannot rely on network communication or maybe don't want to bother with a client/server environment.

              I think you might be misunderstanding what JNI is. Each Java runtime provides its own implementation to the native underlying system libraries. Java does not communicate through JNI for I/O of any kind.

              JNI itself is a generic abstraction layer to the underlying operating system. It provides a mechanism whereby dynamic libraries not directly supported by the runtime engine can still be accessed by a Java application.

              Threading, sockets and GUI are implemented via the native system libraries. AWT used to be very slow (as opposed to just being merely slow today) due to its own multi-layed abstraction. But at no time was JNI the conduit for these systems.

      I'm a Java developer, and have been almost from the very start of Java. While I tend to agree with you at first, I would like to point out some benefits of using Cloudscape.

      Over the years I've had a few (small, hobby) projects, where I really felt the need for a database which did not need to be fast nor did it need to be huge. So I tried Cloudscape. And while it isn't the fastest around, it gets the job done.

      The easiest part is that you can just bundle it with your application, without writing a single line of code!

      I've tried MySQL, but I still need to install it prior to being able to run my application - no need for that with Cloudscape.

      But, granted, it is not the fastest out there. If I need a *real* database, I just use Oracle.

    I was struck during our search for a database for our product by the paucity of systems that fulfill our requirements:
    1. Small and embeddable
    2. Open source
    3. Native C++ interface
    It seems like practically all the databases that fill the first two requirements are written in Java and use it as their primary API. Finally we settled on Sleepycat's Berkeley DB XML, which meets these requirements and has a native XML interface to boot. The one potential caveat is that they use a hybrid license that lets users "opt out" of the GPL by paying a fee, after which they can distribute their product as closed source. Personally I think this is a great thing (always nice to have more options and you don't have to pay anything if you product is also open source), but I'd be interested in the views of the /. crowd.
