A2003, split database on a network how can the database be opened read-only using a shortcut? Does this mean that read-only users can not update any data for sure? I am having difficulty understanding the meaning of opening a db exclusively. If db has both fe and be set to open exclusively -- I thought (naively) this meant only one person could open their fe and use it to make changes to data at any given time. Have tested and this is not the case. Could you please explain. How is opening exclusively different from opening in shared mode? In which circumstances should you choose to set the options to open exclusively or shared?
