FM Server - provides access to all the files
FM Pro - connects to the server for the files
1 copy is all you need of server.
Thanks for your input. I realize I only need one copy of server. To rephrase the question, I am wondering how many Standard FM Pro licenses are needed in a typical setting.
I am thinking of getting one standalone FM license for setting up the filemaker database, correcting fields, layouting, etc. that is then shared via FM server. Is the web interface provided by FM Server mighty enough to replace the standalones for non-administrative users?
FileMaker Pro is necessary on ALL workplaces unless you use IWP or PHP API.
Server just to allow get necessary amount of clients to database OR make PHP access.
Cheapest is Server and one FileMaker Pro (creating databases).
The via IWP (again - IWP is not the same as FM but close from client point of view) or PHP (with Server you get PHP Assistant) clients get access to database.
I believe that you need Filemaker Server Advanced instead of Filemaker Server in order to host your files so that users can access the file via their web browsers. There's a significant difference in price between the two so look before you leap.
