RE: Using hibernate

2005-03-14 Thread Allistair Crossley 
We use straight JDBC and Hibernate on our intranet. JDBC is used for where 
speed is needed, like hitting the database for nav functions etc... but 
Hibernate for pure intranet based applications like holiday forms or purchase 
ordering, because it's nice to persist/unpersist complex application model 
objects without worrying about all the SQL hassle to do this, and speed is not 
an absolute, though saying this Hibernate does not visibly slow anything down 
at all, it's actually v. quick and easy. Initial learning curve but once you're 
in it's good stuff to use, and boasts being the most widely used ORM on any 
platform, so there's good support (part of Jboss now too I believe).

That's my 2p.

Allistair.

 Subject: Re: Using hibernate
 
 
 I have used straight JDBC, Hibernate, and iBATIS. 
 
 For me, the sweet spot is iBATIS. It provides very near the
 performance of JDBC, without the complexity.
 
 IMO, I will use ORM when database vendors support it directly, not
 when I have to wrap my database in a ORM layer.

Take a serious look at Cayenne:
http://www.objectstyle.org/cayenne/
Much nicer than Hibernate in my opinion.
Cayenne is the open source sibling of NeXT's Enterprise Object  
Framework:

http://c2.com/cgi/wiki?EnterpriseObjectsFramework
Which is still somewhat available from Apple:
http://developer.apple.com/documentation/WebObjects/Enterprise_Objects/ 
index.html

Does anyone has good/bad experience using similar technologies?
Yes. Both. Most of the time those O/R mapping tools are overkill. YMMV.
Have you considered _not_ using a SQL database in the first place?
Cheers
