I want to build a small warehousing application for my company. We have a central warehouse which distributes to 8 sales points across the country. They insist on an in-house solution. I am thinking to setup a central mySQL db Linux server and have the branches connect to it to store sales.
Queries to the db from the branches will be minimum, maybe 10 per hour. However I need all the branches to be able to store each sale data ( product ID, customer ID ) in the central db at peak time at most once every five minutes.
My question is can I get away with simple 24mbps/768kbps DSL lines? If not what is the bandwith requirement? Can I rely on a load balancing router to combine additional lines if needed? Can you propose some server hardware specs?
Ok let me clarify this a bit. All I need is to store data (prodctID, itemsSold) when something is sold and to retrieve availability in other stores. Eg to return quantity of certain product in other branches in order to re-supply from central warehouse or have some other branch send something over. I am guessing one row (branchName, itemQuantity) per every other branch (7 branches - 7 rows) whenever a branch is out of something. I think the data sent is minimal but I dont know if there is overhead. How can I estimate that?
