 David Van Couvering 's BlogDecember 2005 ArchivesDerby Demo hits a nervePosted by davidvc on December 15, 2005 at 09:25 PM | Permalink | Comments (2)I think we hit a nerve with this demo. I think many of us within the Derby community recognized the potential for Derby within a web browser environment, but it's wonderful, great, fantastic to see how the community is "getting" it and running with it.
http://www.sauria.com/blog/2005/12/13#1440 Apache Derby as Local Web CachePosted by davidvc on December 13, 2005 at 05:08 PM | Permalink | Comments (5)I'm here in San Diego attending ApacheCon. This is my first ApacheCon, and in general I like what I see. It's very low-key, generally laid-back, and there is a large focus on getting to know each other. I attended my first “key signing party” yesterday. This is advertised as an important way to grow Apache's “web of trust” by getting others to sign your PGP key, but a great side effect is that this is one of the best ways I have seen to get us introverted geeks to actually pull our heads up from our computers and say hello to each other. We have been working on a great demo for Derby, showing how it can be loaded from a web browser and run as a local store or cache that runs on the client machine. We've been excited about this for a while, once you get that you can do this, it opens the door to all sorts of ideas. Francois Orsini, one of the engineers here at Sun, who worked at Cloudscape years ago, dusted off the demo he did in 1998 and put a new AJAX paint-job on it. We demonstrated it at Tim Bray's keynote today, and it was really well received. We showed not only that the database runs invisibly (it's hard to believe that one is back there), but that, because it's local, every field change can get stored immediately. If you crash the browser in the middle of a form page, the data you typed in is not lost. It also means you can run applications without being connected to the Internet, storing data locally on the client machine. It looks like Mozilla has been looking for something like this, and others are interested as well. A lot of people are asking for access to the source, so we're talking about putting it into a samples directory of Apache Derby so not only can you get it, you can also improve it and make it better! I do want to put in a big Thank You to Francois, he has worked very hard on this demo and it's really helping people get the “aha” of what you can do with a small footprint Java database with a little creativity. Web-based apps with fast, secure, robust, client-side relational storage – wow. The other announcement was the new name for Sun's supported distribution of Apache Derby: Java DB (or “open Java DB”). Some folks have asked me why we chose this name, and really I don't know. Sun's just too big a company. I do know that Apache owns the trademark “Apache Derby” and the only distribution that can use that name is the one you get off the Apache web site, so we had to give it some name. I liked Bernt Johnsen's suggestion that we call it Cardiff. | |
