Database shootout

Following on from my posting about DB2 Express-C, I was very interested to read an article comparing Cloudscape/Derby with MySQL. Cloudscape is a slightly different product to both DB2 Express and MySQL, since it can be embedded inside your application and doesn't need any specific administration tools. The database is hidden from the user. This can be a huge advantage, depending on your application requirements.

For example, in WebSphere Message Broker version 6, the Configuration Manager now uses Cloudscape instead of DB2 to store its information. This means that it is easily portable (it now runs on all of the WMB supported platforms), and you don't need to install and use DB2 if you don't want it.

Take a look at Cloudscape, also known as Apache Derby, if you are interested in a lightweight embeddable database. If you need something a bit bigger and don't mind some administration, DB2 Express-C is worth a look.

I've been revisiting some of the images I took last summer. So far, one of the results has been a small series of pictures of butterflies. All of these were taken on one particular great day in Poland, using the kit lens that came with the 350D. I hope to get an opportunity to use the new lens on these kind of close-up shots in the future – guess I'll have to wait for better weather to come along!

So far, the first one shown has proved very popular and according to Flickr Scout is currently #19 in the Flickr Explore pages.
