Thank you for your post.
FileMaker Pro will allow you to share a database file with ten other FileMaker Pro users. If you need more than ten users accessing the database, then you will also need FileMaker Pro Server.
FileMaker Pro Server merely serves the files. Everyone still needs FileMaker Pro to access the file.
FileMaker, Inc. does not develop any additional solutions except those that come with the product. You are free to modify those solutions. There are thousands of FileMaker developers, so you may want to contact one in your area. Please see our web site for a list of consultants nearest you.
