I'm creating an application in C #, but I had a question. Which database is used so that it is not necessary to install the database on the client system? For example: If I were to use Postgresql how could I integrate the application with the database at the time of installing without having to install the DBMS itself? Not that the DBMS is Postgresql, would it be something like SQL Server that is already included in the C # or SQLite library itself?
