the designing.making/deploying/management of a distributed database?
or do i need to buy the versions for the above?
if it 10g express has this support, will there be a central point to which my web application will connect, or do i have to write connection strings to connect to each server making "the distributed database "
please also refer to this post Oracle distributed databases and MSVC
Oracle Express Edition is limited to a single CPU and 4GB of data on a single server. That's why it's free. If you want to use it in a distributed configuration you will have to write the glue yourself.
