I didn't mention any details in my previous post. Basically, the Brainwave database is very similar to an RDF triple store which captures semantic information. There are some fundamental differences however, (e.g. a simplified API, no schema, ability to store objects by introspecting and breaking it up into its primitives etc.) In general, it works well if you're dealing with a lot of unstructured data or even semi-structured/structured data where the structure is constantly changing. Key areas of benefit are in terms of integrating legacy databases and also analytics heavy applications. This is because there is no concept of normalized/denormalized schemas so your data does not need to go through any structural transformations in preparation for OLAP use. Since we're new, I probably won't recommend using it with very very large data-sets. However, we've seen significant benefits with small and medium sized data-sets. At any rate, whatever you choose, you can import and export all data in CSV/XML at any time so your data is safe. Some of the benefits I have described above have been shown to be areas of concern when dealing with SQL stores. There is a lot of research and many opinion pieces available on this subject. I'd be happy to discuss any aspect with you further. Sorry for the delayed response. I've been in and around airplanes for the last 24 hours (and its not over yet). -Prateek -- http://mail.python.org/mailman/listinfo/python-list
