Comments on: ODBMS where did they go? Trends and Information on Big Data, New Data Management Technologies, Data Science and Innovation.

If so, how can I get hold of it?

Thank you in advance.

They went commercial……

I think odbms’s went from research db’s to commercial db’s to fast. They went for the money as they thought everyone would drop relational db’s.

That is why I like open source object databases. I think they give new and student users time to play with an odbms and understand it better. Like MySql and Postgresql.

And odbm’s are not taught at enough universities…..well not in SA…….

And there are more architects that don’t know what an object database is…..

They have adjusted though…

2) Matching Programming Languages and Databases has always be a difficult task.
It is still is.
Now the “Impedence mismatch” is more than ever a real problem felt by the market.

I’ve got a pair of questions on your message.

1) This phrase –
“And relational databases are still there… They changed, yes, but they are still there.”
– sounds like you think that possibility exists that relational DB can disappear or become unnecesarry. Is it true?

2) The one of main trends of long DBMS history is the separation between the ones and applications. How this idea can be joined with attempts to link current OO-languages designed for application creation (like Java or Csharp) and ODBMS. I mean these OO-languages has a lot of features which are useless for DBMS and, on the other hand, DBMS need for other language features (like transaction, security, data queries ets.). For example I think that possibility to desribe some enterprice in OO-way is enougth for real _O_DBMS language. May be special OO language should be more useful for ODBMS which allows describe the modelled enterprice as set of object and which is absolutely independent from client side aplication including their languages?
