I'm trying to develop a project with the possibility at the begin of a new File to choose between mdb file or MSSQL server as a data source. Now my question is what is the best solution to program this senario? I think to use two dataset using a MSSQL and second for mdb? any suggestions from proffesionals experiences this before. thanks by advance
my code for now is this ? do you think is that good idea to begin?
interface IDatabase
{
void Connect();
void Disconnect();
DataSet Fill_Customers();
int Update_Klanten(string Naamcontactpersoon, string Original_Klantnummer);
int Update_Klanten();

//implement here
}

{
//implement here
}

{
kta.Fill(ds.Klanten);
