Entity class persist by self

Use ToolKit create entity class :
    [DataTable("Customers")]
    public class Customer:Grove.DataObject.EntityClassBase
    {
        int _CustomerID;
        string CustomerName;
        string CustomerURL;

        [KeyField("CustomerID")]
        public int CustomerID
        {
            get{return this._CustomerID;}
            set{this._CustomerID=value;}
        }
        [DataField("CustomerName")]
        public string CustomerName
        {
            get{return this._CustomerName;}
            set{this._CustomerName;}
        }
        [DataField("CustomerURL")]
        pubic string CustomerURL
        {
            get{return this._CustomerURL;}
            set{this._CustomerURL=value;}
        }
    }

Persist by self :
    Customer c=new Customer();
    c.CustomerName="tryitsoft";
    c.CustomerURL="http://www.tryitsoft.com";
    c.Insert();//insert a new customer
    c.CustomerID=1001;
    c.CustomerName="chengdu tryitsoft";
    c.Update();//update customer
    c.CustomerID=1002;
    c.Delete();//delete customer
    c=c.GetObject(1005);//retrieve a customer
    string filter="CustomerName=’tryitsoft?quot;;
    DataSet ds=c.GetObjects(filter);//retrieve customers by custeomr name

Description : if you want to entity class can persist by itself , entity class must extend Grove.DataObject.EntityClassBase

Relation query by entity class

Use Tool Kit create relation entity class :
[RelationTable("OrderRelationQueryResult",BeginWithTable="Orders")]
public class OrdersRelationQuery
{
    [RelationReflect("Orders","Order Details")]
    [RelationField("OrderID","OrderID")]
    public string Relationship_1
    {
        get{return "[Orders].[OrderID]=[Order Details].[OrderID]";}
    }

    DateTime _RequiredDate;
    [DataField("RequiredDate",TableName="Orders")]
    public DateTime RequiredDate
    {
        get{return this._RequiredDate;}
        set{this._RequiredDate=value;}
    }
    int _ProductID;
    [DataField("ProductID",TableName="Order Details")]
    public int ProductID
    {
        get{return this._ProductID;}
        set{this._ProductID=value;}
    }

}
Relation diagram in Tool Kit :

Execute Query by relation entity class :
    IObjectOperator oo=ObjectOperatorFacotry.GetObjectOperator();
    IObjectQuery oq=oo.NewQuery(typeof(Customer));
    oq.Filter="";//use entity property name to set sql filter
    oq.OrderString="";//use entity property name to set order string
    ArrayList result=oq.Execute();
