I'm not an expert in this area, but I think some more information is required for you to get the answer you want.
When you say 'sync' do you mean one way, i.e. the db is updated on PC and not on the device?
Will the devices that need to get the information be on the same network, or will it need to connect over the internet?
From my limited knowledge of this area, there are a number of ways you could achieve this, FTP, Webserver and PHP, or even possibly email (I think the intents are available now).
Most of them will require some kind of server, what kind and how it's implemented will depend on what access is required (local or internet).
If you can provide as much information as you can, it will give someone who is an expert in this area a chance at outlining a solution for you.
