RE: Jim Gray article on Next Generation Databases
I like this part: "One interesting development worth noting, however, has to do with the integration of database systems and file systems. Individuals who keep thousands of e-mail messages, documents, photos, and music files on their own personal systems are hard-pressed to find much of anything anymore. Scale up to the enterprise level, where the number of files is in the billions, and you've got the same problem on steroids. Traditional folder hierarchy schemes and filing practices are simply no match for the information tsunami we all face today. Thus, a fully indexed, semistructured object database is called for to enable search capabilities that offer us decent precision and recall. What does this all signify? Paradoxically enough, it seems that file systems are evolving into database systems-which, if nothing else, goes to show just how fundamental the semistructured data problem really is. Data management architects still have plenty of work ahead of them before they can claim to have wrestled this problem to the mat." Actually, it will be sufficient to wrestle down the varchars for most problems that are problems. Discipline does the rest. The longer the spell, the more uncertain the magic. len From: Ken North [mailto:kennorth@s...] > Perhaps I'm reading too much into this, but in Gray's article, the > vision does not seem to include a middle tier.

How to distribute logic - what belongs in the database and in the middle tier -- is an ongoing debate.
