Dear all,
I'm a totally newbie and try to implements an LDAP-application over MonetDB/XQuery due to efficient search performance of column-store. Like the example XQueryLoad.java does i have succeed to import a XML-file and now come my questions:
How can i manipulate my XML-files with JAVA? Like doing searches and changes over XML-files.
If I understood correct, you load your xml documents in monet. So the next step is to send the relevant xquery queries to monet using the jdbc drivers and wait for the result:) If you are talking about manipulating some xml data inside java then you would use the main memory representation DOM provided by the standard java library.
How is the performance of Subtree-search? Like doing searchs over the whole tree or any subtrees.
I think you will be satisfied by the response time of Monetdb:) However, it has to do with what you will be searching and what your queries will be doing. I would suggest to test some queries with the monet client (command: mclient -lxq) to see for your self.
As once discussed in http://comments.gmane.org/gmane.comp.db.monetdb.user/1027, i'm in the same situation.
This thread is about monetdb5 and mal, while you will be using monetdb 4 (using mil) and xquery (I dont believe you have to get "dirty" with mil though). Hope i could help. lefteris
Best regards, Chaojing Yang
