Data warehousing update, part 1
110583
A look at Oracle, ParAccel and Calpont A lot has been happening on the data warehousing front lately. Earlier this summer, Oracle announced its Information Appliance initiative and, in particular, a partnership with PANTA Systems. Then, more recently, ParAccel has announced a product re-positioning, Calpont is finally talking about its entry into the market, and both DATAllegro and Netezza have announced new product releases. In this article I am going to discuss Oracle, ParAccel and Calpont (for reasons which will become obvious) while in the second part I will direct my attention towards DATAllegro and Netezza.â¦

Realistic, or just a stick to beat vendors? Traditionally, enterprise data warehouses (EDWs) were regarded as systems of record. Thought of simplistically, queries were either run directly off the EDW or from a data mart that referred back to the EDW as and when necessary (hence its status as a system of record).â¦

Sam  posts an interesting proposal.  This is better than the HTTP delta suggestion but still has a few issues.  The client needs to know the ETags before it can start performing differential fetches.  With date ranges you still preserve the initial archive query.  For example when you first subscribe to a feed you could fetch 30 days worth of posts.  If you like the feed you can even fetch *older* posts which could be really cool.  Also even if you still use faster checksum algorithm like CRC32 or Adler32 you still have an O(N) performance hit for your document.  If you have a btree on your post dates you will gave O(log(N)) for search for a much smaller string (64bit in most situations).  F ...
