Case Study Case Study : ‘Sydney Gifts’ ‘Sydney Gifts’ run a
store selling good quality antiques and have been in operation for
twenty years. They currently maintain details of every piece they
sell in a manual system. ‘Sydney Gifts’ has always been run by the
same owner/ manager Mr Smith. Mr Smith's son has just joined the
business and thinks that using a computerised system would make
managing their orders, stock levels and records management easier.
Currently they divide their stock into three categories furniture,
china art and paintings. For furniture they store the following
details current owner, approximate age, type, style, construction
material, finish, condition, notes and price. For paintings they
store current owner, approximate age, style, condition, notes,
price, artist and medium. For china they store current owner,
approximate age, style, condition, notes, manufacturer and
construction material. The managers also want to be able to run
sales reports at the end of every month. ‘Sydney Gifts’ also sell
antiques on behalf of some of their existing customers so that they
may sell the same item more than once. When this happens, they go
back to the original record of that piece and record the details of
the new sale price, owner etc. This is done so they can maintain
the provenance of the item. It is very important to both Mr Smith's
that this system is very accurate and quick to use. They would also
like a better way of maintaining customer details so that a
customer could tell Sydney Gifts that they are looking for a
particular item. That item could be placed on a "wish list" and the
customer notified when the item is located. As well as the standard
attributes for an item the wish list will store the date the
customer registered the item on their wish list and the top price
they are willing to pay. ‘Sydney Gifts’ have many customers so that
sometimes more than one customer may register that they are looking
for a particular item. When at least two customers are looking for
the same item it has been decided to offer the item to the customer
who registered the item on their wish list first.
