Ahh, someone like myself! A refreshing change from the people who know
everything, for small values of everything.

I don't agree. I've been through lots of "revolutions" over the course of
Assembler to structured programming in 3GL to OOP. Flat files to indexed files to hierachical, codasyl, and relational DBMS. Raw iron modems to Arpanet to Internet.
Mainframes to Timeshared machines to minicomputers to desktops and palmtops.
And so on.
I think the revolutions are more apparent than real. Most of them gather momentum outside of the general view, and then suddenly bloom when they are ready for prime time.
When was the floppy disk invented? 1970
When was the first "object oriented language" developed? 1967 (Simula) or
When was the relational model applied to database systems? 1970 or 1982 when the commercial world took over.
When were the first computers connected in the Arpanet? 1970 When was the first Intel microchip porcessor? 1972 (the 4004)
And so on.
All of these things that seemed so "revolutionary" when they burst on the scene were actually years or decades in the making.
Even the wrold wide web. Between Vannevar Bush and HTML there was a long progression, including hypertext itself, and markup lanaguages.

You make a good point here. But I think the 6% figure is just a reaction to
the "overselling" of DBMS licenses
during the last 15 years or so. People bought Oracle, DB2 or SQLserver licenses not because they really wanted to manage a "data bank" in the classical sense at all. They just used SQL based DBMS software because "it's the latest thing" or "everybody else is doing it, and they must be really smart."
Those are lousy reasons for choosing any tool, and a DBMS is no exception.
What's interesting is that it's still growing. Those people whose career
depends on 40% growth rates are toast.
But that's true in every field: insurance, real estate, agriculture, and even social security.
BTW, I wouldn't call it "centralized" anymore. But I would call it "integrated". What matters is not whether the data is kept in the same placed but whether it can be used together.

You are right on here. Integrating disjoint and fragmented data is going to be around for a long, long time. Much longer than the DBMS fad. The thing is, it not only takes someone who is wise, knowledgeable, and canny to do it. It also takes a reasonably smart manager to know that it needs to be done. It's going to take a while for the market to permit those who use stategic long term data strategies to gain the commercial advantage over those who fly by the seat of their pants.
I'm not sure I can wait that long.

A fascinating sub topic. Having grown up in Latin America, I know Latin
much better than Dan Quayle did. ;-)
But Greek has all these neat features like the aorist tense and the middle voice.
It seems like Greek was invented for philosophers, while Latin was invented
for engineers and generals.

There are no easy choices. Don't worry about making the wrong one. Received on Tue Aug 31 2004 - 23:26:00 CEST
