Creating An Update Database For A Loyalty Points Scheme

hi i want to create a loyalty points scheme though a database,
general rulse apply 1 point per £1,

when the customer spens some money the staff then go to the machine and input the relevent data.

then a statment will be printed out for that customer with the points to date, and thier purchase the amount of point collect with the new total.

To search the full name and postcode would be adiquit as the printed statment could be lost and so could the customer id get confused by the customer.

for the report the layout would look like this:
eg

customer ID
cathy smith
e-mail,
address,
postal code,

02/12/2007 points to date 200
05/01/2008 puchase made £30.00
05/01/2008 new points total 230

if they use points it would look like

02/12/2007 points to date 200
05/01/2008 puchase made £30.00
05/01/2008 points use 125
05/01/2008new points total 100

point can be enterd manually and removed manually as customers want to save like a saving scheme

please help me with is as i have no idea where to start and if it posible, and limited knoledge of access

thanks in advance
