Three tier application data access layerI am developing 3 tier application in windows based c# application.
I want to create a common method in Dal for performing dml operations like insert, update, delete using ado.net and not using factory classes approach i.e. generic Dal.
Following is sample structure of my method:
// DTO is data transfer object or entity layer for passing values to DAL
public string AddUpdDel(DTO objdto)
How would I achieve it ?
