C# Multiple users Read/Write to database at the same time
<p>I want to connect a C# application with winform which I am planning to deploy to 600 users at my organization. multiple users need to connect and read/write to a network database file at the same time. what is the best way to achieve that?
is it possible doing that with excel/access/streamfile to txt or I have to do it in SQL?</p>

<p>Is it possible to find online some open-source code for this which can be manipulated?</p>

<p>Thank you,
Ori</p>
