In all of our software user management is always charged to the database and never the program, this is because it is always better to have two different layers rather than just one. How can you find the program you can use various data providers, this is because we let the data source configuration open window directly with the consumer configuration OleDB. For example, you can connect dozens of stations to a central server such as Microsoft SQL Server or Oracle or MySQL on Windows or Linux yet, it is important to have the drivers OleDB registered in the system where you launch Calus Plus (soon be releasing along with all our software a OleDB driver for MySQL written entirely by us in ATL).
As for the settings of users’ reading and writing, everything is dependent on the server, so that’s where you need to set these privileges, the program for its part will give an error if someone accessed in read-only mode and want to edit the data in a table . To do the same thing with an Access file shared on a network (recommended only for some users and for small files), you must configure a system file, all is explained in this interesting article on the safety of the Access database.
Of course, all this work can be done by people who understand a little of server administration data, so our advice is to contact a consultant who can help you in this work.
