XMLRPC or CORBA?
I am going to use Xindice as a backend DB for a J2EE web app in Java.
Which API do you think is better to use in order to acces the DB ?
- the XML-RPC API
- the XMLBD (CORBA-based?) API
The key factors are:
- speed
- easyness to write code
- future support of the API
Are these APIs both created by xml.apache.org team or by a third-party?

First I would like to say that people who starts a mail discarding other
peoples thoughts with "nonsence" really don't deserve to be answered,
but..:
I don't mean that object oriented databases are dead, but given the amount
of effort given to the hype of object oriented databases, very few
products remain. The reason has nothing to do with quality or that the
idea of object oriented databases was bad. I have used Versant myself so i
know. The problem was they didn't have the support of major software
wendors who could sell them to customers (Additional sales).
The mejor software vendors already had good, well tested products, and
instead of making new ones they buildt in support for object storage in
their existing products. Then there was no need for their customers to go
out to by a object oriented database, so the market disappeared for those
who made "native" object-oriented databases, even if they maybee had been
a better solution technically (as Cedric seems to mean)
We could come to see that development for native xml databases to, as
Oracle and others are already building in support for xml in their
produccts (all though they have not come very far yet)
In fact, to my knowledge only Tamino from AG Software has a big
corporation promoting it. Or are there others??

Nonsense.
First, it is very difficult to make a clear difference between traditionale
databases and XML ones.
In fact, the only difference is the way you acces the datas. But in fact,
how are stored the datas is each database problem.
In fact, XML databases, [ i mean databases which allow XML manipulation
(providing API specifics or standardised), even if they are also traditional
ones (Oracle) or not (XIndice) ] will be usefull if they complete the need.
For those who thinks that Object databases are dead, they are wrong. In
fact, there is at least one powerfull database which work properly :
Versant. There is numerous application, in which it beats Oracle.

A few weeks ago I tested Xindice and eXist in terms of storage of mesg.
per second and found that Xindice is much faster than eXist
we're talking about > 300 msg. per second against 2(two!) msg per second
on the same environment, using the same XMLDB-API.
eXist uses XML-RPC and Xindice uses XMLBD (CORBA-based) API.
Go and try for yourself.

I don't know and I don't think anyone can make anything but qualified
guesses. Maybe xml databases themselves will vanish like the object
databases did.

Corba is not a bad thing because it is very very faster than xml-rpc.
Perhaps xindice should implement a layer protocol and can be compliant for API access via Corba, Soap,
...
via a Driver layer ...
perhaps you can get some idea in xmlBlaster project : http://xmlBlaster.org/
This software can be accessed via many langage via many protocol. A new protocol just need to be
implemented like a driver...
I'm not expert, it's just a proposal ;o)

I am going to use Xindice as a backend DB for a J2EE web app in Java.
Which API do you think is better to use in order to acces the DB ?
- the XML-RPC API
- the XMLBD (CORBA-based?) API
The key factors are:
- speed
- easyness to write code
- future support of the API
Are these APIs both created by xml.apache.org team or by a third-party?
