Hi
Soumitra,
thx for ur
reply.
Why
file system seems to be inconvenient for me?
1. I
already have some data in the RDBMS database. So I have to manage (backup,
maintain etc) 2 things the rdbms data and the xml files on the local file
system.
I
would like to store everything in one type of storate
system.
(well
I can get rid of the rdbms by keeping this data again in xml
files)
2. If
I store the xml files in database, security of the data can be manages in much
better fashion
3.
This is what I assume ==> If I store the xmls in xml aware database system,
--
creating DOM from the blob
--
performing queries
--
performing XSLT , XPath might be much efficient
--
besides I will need indexing and searching capabilities
Basically this is my requirement;
I have
built an internet based application; where new users come in; create account; a
new xml file is created for each of the new user.
His
personal information (name, email address, etc, his profession related data)
will be stored in the xml file. (This data is highly structured and
hierarchical)
I
expect the size of each xml to be 10k to 30k.
The
same user can come into the system again to modify and update his information;
that time the application builds DOM and keeps the DOM in the memory till
the user logs out.
Other
users can come into the system and can view the data of other users. There
maintainance of DOM is not required but lot of XSLT and XPath queries will be
performed. This is where I need to achieve better efficiency (I have not yet got
any answers to it)
I want
to to perform the XSLT and XPath as efficiently as possible.
Search
capabilities;
1.
indexing on the elements and attributes of the elements
I
should be able to specify in the configuration what elements and attributes
should be indexed;
2.
full text indexing
Now there are few responses to this thread which
suggest to use eXcelon and Ipedo. I will start evaluating them. But I wonder if
I can use them.
Mine is not an enterprise application; I plan to price
tag this application at about US$ 2,000-4000. And using these specialized xml db
servers would be commercially unviable. That is why I am looking for a no cost
solution. However I am definitely looking for prospects where a high performance
is required for the custiomers of my product. There I can provide a customized
solution.
Hope
this gives more Idea as to what am I upto.
regards
Haresh
