Sorry, How would I show this?

Again, forgive my skill level here. What is the best way to show this?

Here are the table schemas

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

SET ANSI_PADDING ON

GO

CREATE TABLE [dbo].[Customer](

[CustID] [int] NOT NULL,

[DealerID] [int] NOT NULL,

[Distance] [int] NULL,

[SSN] [nvarchar](11) NULL,

[Last] [nvarchar](50) NULL,

[First] [nvarchar](30) NULL,

[Address] [nvarchar](60) NULL,

[City] [nvarchar](35)...

What is the best way to give you this information? As far as the schema and clustering? I have never created and clusters before.

Sorry for my limited knowledge here.

Here is how my tables look now.

Mail

100 1 F22.123124 7/1/2012

100 2 F22.123124 7/1/2012

133 1 C16.112323 7/3/2012

200 1 S15.434552 6/30/2012

I am joining these 2 tables based on DealerID and CustID. The powers that be here at my office want the customer table...
