Home -> Community -> Mailing Lists -> Oracle-L -> RE: Java vs. Perl
Cary
Well said, as always. Can you pinpoint any parts of Java that are good for a DBA to concentrate on? I've learned just enough OOP to understand that languages like Java don't always lend themselves to clear transaction boundaries. Mostly I've used that as a well of empathy so I can look sympathetic and nod and agree and then say "yeah but you've got to figure it out somehow."
I push the Java developers to use PreparedStatement. This causes Java to use bind variables. If I tell a Java developer to use bind variables, they look blankly, but they do understand PreparedStatement, or can at least go back and look it up in a book. Aside from the benefits in Oracle, it also defeats the SQL Injection hacking technique.
I would gratefully appreciate any other points you would care to share.

The only reason I would recommend for a DBA to learn Java is if that's what your applications are written in. If you have any performance responsibilities, you MUST know something about the language your apps are written in. Substitute whatever your app is written in for "Java" in this paragraph (PHP, COBOL, C++, C#, Visual Basic, ...it doesn't matter; whatever your app is written in). This, by the way, is why you MUST understand SQL and probably also PL/SQL (if you're lucky); it's part of what your apps are written in.
Perl is another story. Maybe your app is written in Perl, but probably not. Even so, Perl, Python, ksh, SQL, PL/SQL, and others are tools that a DBA might use to create new tools that help you do your job more effectively. There's probably someone out there who writes DBA scripts in Java, but whoever you are, I don't envy you. :)

There are many reasons to use one tool over another. For me and my company, perl offers faster development time. What it boils down to, both tools allow you to connect to the Database so anything that can execute SQL or pl/sql is fine.
In the past, executing the same business logic with medium to big amount of data (100k+ records) is faster in perl than java. Unfortunately I=20 don't have any statistics to back to support this. Anyone?
The java developers that I know of, uses ODBC or OCI, to communicate =
from
the java application server (ATG) to 8i. I don't know of anyone
using=20
java and communicating to Oracle's API. =20
Hi, please there is another reason than simple know perl, to use perl
instead of Java.
I always heard Java had more advantages than perl, including the fact =
that
Oracle include it in the database.
Now you are talking as much about perl, and I am thinking to study java,
=
I
am asking which is
best. for most purpouses.
Thanks :)
