The Models can be used also as table definition directly.

<br />
<br />
Following section demonstrates how to define the models and tables.

<sample>
    <pre lang="c#">
        using Odb;
        using Odb.Table;
        using System;
        using System.Linq.Expressions;
        using System.Collections.Generic;

        // Column attributes can be defined at once to use with [Ref]...
        public enum Ref
        {
            [Column("year", Length = 4, DefaultValue = 2000, MinValue = 1900, MaxValue = 2100)] year,
            [Column("note", Length = 100, DefaultValue = "")] note,
            [Column("id", Length = 5)] id,
            [Column(DateFormat = ColumnDateFormat.OnlyDate)] dt
        }

        [Table(Name = "orders")]
        public class Orders : Base
        {
		    [Column(Ref.id)]public int OrderID          {get;set;}
		    [Column(Ref.id)]public int CustomerID       {get;set;}
		    [Column(Ref.id)]public int EmployeeID       {get;set;}
		    [Column(Ref.dt)]public DateTime OrderDate   {get;set;}
		    [Column(Ref.id)]public int ShipperID        {get;set;}

            public List&lt;OrderDetails&gt; Details { get; set; }


            protected override Expression&lt;TableConfig&gt; Config() =>
                (x) => x.SetPrimaryKey(OrderID)
                                .AddIndex(OrderDate);
        }

        [Table(Name = "order_details")]
        public class OrderDetails : Base
        {
		    [Column(Ref.id)]public int? OrderDetailID   {get;set;}
		    [Column(Ref.id)]public int? OrderID         {get;set;}
		    [Column(Ref.id)]public int? ProductID       {get;set;}
		    [Column()]public decimal? Quantity          {get;set;}
        

            protected override Expression&lt;TableConfig&gt; Config() =>
                (x) => x.SetPrimaryKey(OrderDetailID);
        }
    </pre>
