Developing database application
I am looking at developing a datbase app.
Is it best to use a connection everytime the user performs an action (i think this is best) or use dataset with datadapters?
There is a lot of data so i believe the first option is more viable - just looking for further opinions.

You cannot use dataset and dataadapters without open connection. You need to create a connection (in any case) and then use dataadapter to populate your dataset.

I know you always need a connection, the difference is the datareader performs the actions directly, the data adapter grabs the required data allows you to modify it then send it back later.
I will be pulling data but only a record at a time.
E.G. list of say outlets clicking on one brings up the outlet in more detail.
What are crystal reports?
Is there anyway of producing reports for printing using VB.NET?
