mysql - Local Sql express 2 way sync to remote server -
i have native windows application (software) local sqlexpress database. need bring data every local install (5000 in number) central server mysql. 1./ don't think able port forwards etc on router @ every local installation , hence wonder what's best way synchronization done. 2./ @ central server should use ms sql instead. there compelling reason stick ms sql @ central level?
regards ravz
at central server should use ms sql instead
yes, , not free version.
you use sort of replication.
is there compelling reason stick ms sql @ central level?
you must joking. read documentation. sql server has nice features in non free versions - replication example. last time tried setting (laptops, ages ago) went transactional replication between sql servers , worked charm.
alternatively can sit down , start writing. there db agnostic sync fraemwork available, or can totally roll own - both valid approaches. should check first can do.
check http://msdn.microsoft.com/en-us/library/cc645993.aspx#replication
you can use transactional replication , use expres editions subscribers against central master database.
