    Great article but I think there needs to be a sequel, er... I mean Part Two that covers the 1990's. Especially some history on the relationship between Sybase and Microsoft in the early days of SQL Server.

    Good article, one for the trivia buffs

    I'd also like to see Part Two, but it should cover the variations offered by different vendors. Might be a little harder to pull together

    Hope this helps

    Hi cppwiz, hi phillcart,

    are you mind-readers?

    Btw, I think I have read something of a company called Sybase, but I can't really remember right now

    Anyway, something in this direction is already planned and in the pipeline.

    if you ask me this way???

    Nothing but a stupid number crunching on this years' forecast and next years' planning and estimating where stock markets will end this year (and usually be totally wrong, that's why I need to work anyway) and integrating this estimation into the forecast and the planning and estimating.....

    SNAFU !!!!!!

    There are some nice comments, in addition to yours, in a paper called

    I will say, I'll answer this very carefully.

    AFAIK GRID computing is like having a single, large virtual computer.

    I'm really not sure what to think of this whole 'unifying thing', although the intention is honorable.

    ...'The 1995 SQL Reunion'.

    Btw, the only source I found where it is mentioned why SEQUEL/2 had to be renamed.

    Good one. In recent days I heard about Hirarchial Databases. What about them? Have they released??

    The hiearchical database model is somewhat older than the relational model. I think the most prominent system is IBM's IMS which (still) runs on older mainframe systems. With the evolution of object-relational or object-oriented DBMS this model has some kind of revival.

    If you could wait some time, I've finished an article on this topic in german. Needs only to be translated to english. Then fine-tuned and hopefully published.

    The recent articles on it left me thinking it is nothing more than load balancing on a cluster style system with replication between node networks.

    The problem I see is that all my encounters with Oracle replication methods means a large possibility for many gaps in data and lags in processing. Our problem management system is on Oralce and the replication has been known to replicate everything but a handdull of records which magicly appear days later.

    No it has more, thankfully thou there are a lot of third party apps and oracle addons you can pay large sums for to fix these. However looking at what they are planning for next release EM they may be finally stepping up to the plate with quality.
