    basicly
    its you only store the data once

    ie
    customer table
    customerID PK
    customerName
    customerPhone
    bla
    bla
    bla

    invoice table
    invoiceID pk
    customerID
    bla
    bla
    bla

    don't put the Customer NAME in the Invoice table as it link by the customerID
    hope this help

    See clear as mud
