I have a WPF C# multi-user applicaton which interacts with Sql Server Express database. Currently I have faced up with the following issue:
How to organize the application and the database in order for several users on different stations be able to work on it , maybe i should put the database file on a server, and make my application on all other stations refer to that server when they interact with the datatbase? If so, how can I provide security of the database file.
Is there any scenario in which I could install my application on server and sign it as server and while installing on other machines point that server?
Any advice on general strategies in such cases would be appreciated.

Thanks in advance!

    For multi-user application, you definitely should put the database onto a server. And because the application is for multi-users, the first screen shown when a user opens the application is the login screen (just like the case of web application).

    Security isn’t a matter, once a database is put in the filesystem, only the users on that computer can access it. And of course, the computer which contains databases is supposed to have only administrators as users. Another point is that Windows may have IIS running, don’t put the database files under public root of IIS so that non-user people won’t be able to download them through HTTP.

    Let’s say the users are working on the same office. You can assign any computer in the LAN as a server and install the database on it. Any computer in the same LAN has a LAN IP (eg. 192.168.1.100), your application can connect to this IP for database operations.
