I think many people have this question:
Let's suppose my company has 3 workers named Andreas, Bruno and Carlos, each of them using its own computer. Because Andreas's computer has OpenERP All-in-One 7.0 installed, he decided to create on his computer localhost the first database of the company named WeAreTheBest_Store and 3 usernames (his, Bruno's and Carlos'). Bruno and Carlos want to have access (from their computers and with their own usernames) to this super cool database that Andreas created. Should they also install OpenERP in their machines? Should Andreas turn off the Firewall from his PC? What should Bruno and Carlos do to have access to WeAreTheBest_Store database (spending less money as possible???)??? Cause getting a server is pretty expensive... What would you guys do? Thank you and please give me a step by step answer.
