. Net L3 architecture development instance-User Registration System

The following is a three-tier architecture instance developed by the user registration system: the database base class uses the Code provided above.

1. Data Layer Development of the user registration module:
Using system;
Using system. Data;
Using system. Data. sqlclient;
Using haisky. htjob;
Using system. xml;
Namespace haisky. htjob. Accounts. accountsdata
{
    Public class user: haisky. htjob. haiskydbobject
    {
        Public user (string newconnectionstring): Base (newconnectionstring)
        {// Direct route connection string}
        Public int create (string user_nm, string user_pwd)
        {
            Int rowsaffected;
            Sqlparameter [] parameters = {New sqlparameter ("@ user_nm", sqldbtype. Char, 16 ),
                                        New
Sqlparameter ("@ user_pwd", sqldbtype. Char, 16 )};
            Parameters [0]. value = user_nm;
            Parameters [1]. value = user_pwd;
            Parameters [2]. Direction = parameterdirection. output;
            Try
            {
                Runprocedure ("if_user_info", parameters, out rowsaffected );
            }
            Catch
            {   }
            Return (INT) parameters [2]. value;
        }
    }
}

2. User Registration business layer development:
Using system;
Using system. configuration;
Using haisky. htjob. Accounts. accountsdata;
Namespace haisky. htjob. Accounts. accountbusiness
{
    Public class user: haisky. htjob. haiskybizobject
