I am making baby steps in creating a simple (test) form using n-tier approach. UI -> BO -> DA. That is, UI through BO asks DA for a record and displays it. As user navigates through records in the table, the cycle "UI->BO->DA" will be done quite often (possibly). The DA is where connection to SQL Server takes place.
Should I close the connection and open a new one on every call to DA or should I make the connection PUBLIC and maintain it for duration of the form being open?
Thank you for any suggestions.
