Consider the following scenario and draw a context diagram of the Estate Agency. Clients wishing to put their property on the market visit the estate agent, who will take details of their house, flat or bungalow and enter them on a card which is filed according to the area, price range and type of property. A similar type of card is filed by potential buyers. Weekly, the estate agent matches the potential buyer's requirements with the available properties and sends them the details of selected properties. The estate agent checks the sale status with the buyer and when a sale is completed, the buyer notifies the estate agent about the sale. Then the client details are removed from the property file, and an invoice is sent to the client. The client receives the top copy of a three part set, with the other two copies being filed. On receipt of the payment the invoice copies are stamped and archived. Invoices are checked on a monthly basis and for those accounts not settled within two months a reminder (the third copy of the invoice) is sent to the client.
