- Seems to be still the case, among the mainstream database products.
- You might have some luck with middle-users (as opposed to end-users)
- such as those providing db's for, say, the publishing industry ---
- a wonderful source of solutions to problems that I, thank goodness,
- seldom see (think about how you store the articles and pictures in
- a magazine; this ad must NOT be near *that* ad, etc.) And, if you
- REALLY want to see the leading edge in OODB technology and really
- awesome record size and relationship problems, take a peek at
- where office automation systems are going (no, I'm being serious).
-
- I agree, though, that really usable blobs would find instant use.
- We started off trying to move our E-Mail/CIM system into a standard
- SQL database. Turned out to be more hassle than the old system, which
- created (compressed) files in a standard unix directory and stored
- the filenames in the database; directories could be nested within
- directories; links could be made for multiple copies; etc.
-
- The standard database, with 1970's technology for locking, journalling
- and space management isn't a very promising engine for such applications.
-
- Pardon me: one exception: Revelation. With 1-64kb records as part of
- the basic file system,and extremely flexible dictionaries, AREV
- can probably handle just about anything you'd like to put on a PC
- or a LAN. But that's a rather limited domain.
