Hi all...

I am looking to study some sort of database certification..I have some knowledge of basic relational database tables and a little SQL but it's meagre.

So I want to know of a good qualification to have that will not be too difficult to pass BUT that goes hand in hand with java development as I am studying SCJP and servlets also....so what would be good MySQL??

Also,why does no-one use Java DB that's bundled with Java(I mean I've never seen it as a knowledge requirement for a job(as opposed to oracle,mySQL)
The OCA seems very advanced(or IT-centric)...

Derby/Java DB is quite new. But I know a commercial product that use it.

Don't know much about DB certification, I think it's not very popular.

Derby isn't really new. It's been part of Apache for 4 years, and been available from IBM before that.

I'd say the reason you don't see the embedded Java DBs (HSQLDB is another popular one) in job requirements is that they implement JDBC, but nothing much beyond that. So if you know JDBC, you can work with them, and there's not much else to learn about it. That's very different from, say, Oracle, which has tons of other capabilities besides pure JDBC.

So it's definitely not the case that nobody is using embedded DBs; SQLite (which is written in C) is part of a number of popular application and operating systems (like Firefox and OS X).

Actually, 4-year DBMS is quite new, if compare to products like Oracle RDBMS(Oracle 3 was released on 1983), IBM DB 2 (if count its predecessor System R) which was developed about 30 years.

Derby is not just embedded RDBMS, it has embedded environment but it can be setup as server as well.

Anyway, I agree that features of Derby/JavaDB cannot compare to Oracle/IBM DB 2. How can 4 years old beat 30 years old ?
