同步中央数据库与多个本地数据库

Question

I have to develop a Project with php mysql for sales management system.There are many

outlet. I want to keep a databse centrally and every outlet have a databse locally. user

entry data to local databse. after a while local data can be uploaded to central databse.

Local data will go to central database, but central data will not go to local database. what will be the procedure for that. (e.g: Synchronization, Replication)

Answer 1

I wouldn't use syncronisation or replication. I would use an import/export mechanism.

Write a little tool which will export the last day/week/month and than send it with an secure line to your main database for import.
