The v2.0 code (in the org module) is not usable to transfer data. This
is because many of the classes -- such as DOMToDBMS and DBMSToDOM -- are
missing. It is usable for writing other v2.0 code.

The most useful thing for me would be writing MapFactory_Database. This
would exercise a side of the map code that hasn't been pushed hard yet.
The other useful (and easier) thing to do would be to update
MapFactory_DTD for 2.0, which might be a good introduction to the 2.0
I've written MapSerializer and am working on MapInverter (it turned up
some design bugs). Other people are working on DOMToDBMS and
MapFactory_W3CSchema. An early version of DBNameChecker is already done
and MapChecker and DDLGenerator are not critical path.
- Hi Ronald and others member,
I've just read your article in:
I already d/l the program and run it, it works fine
what I'm asking now:
1. what's the different between this program and xml-dbms you made
(advantages), except its ease of use
2. I still cann't make xml-dbms run with HypersonicSQL database (Java
open source database), I don't quite understand about map-file?
do i have to write it manually or the mapping tool included in xml-dbms program?
if yes how do I do it
sorry if this is already in the manual, because i'm not really
understand (english is not my native language)

Both products are based on the same object-relational mapping. I think
the advantages of DB/XML Transform are:
1) Bigger feature set. For example, it can create calculated values and
add new fields.
2) GUI-based mapping tool.
3) Update the database. (XML-DBMS v1.01 can insert and read data, but
cannot update or delete data.)
I think the advantages of XML-DBMS are:
1) Free, with no license restrictions.
2) Includes source code, so you can change it if you want.
3) Can maintain order information in the database. This is necessary for
Version 2.0 of XML-DBMS will add some of the features currently found
only in DB/XML Transform, but not all of them.

with the GenerateMap sample, but these usually need to be modified by
hand for the highest efficiency.
For information about how to write maps, see the sample maps (in the
samples directory) and sections 3 and 4 of the readme file.
