ACKNOWLEDGEMENT
I am indebted to my computer teacher,
Ms Geetu Munjal
for her guidance and whole hearted support
in the making of this project.

2:[1]
I call this software ‘THE CUBE’.
This is mainly because of the fact that it performs 6 types of tasks.
Three of them are general while the other three are user specific.
The Cube is made for 3 types of users:
A Customer, A Supplier and The Manager.
A more elaborate coverage of The Cube’s function can be seen in
‘THE 6 FACES OF THE CUBE”.
INTRODUCTION
This software is made to cover the processes associated with an Antique Store.
Its applications extend to customers, suppliers, cashiers, managers
and other staff members alike.
Besides allowing us to view and search the items on sale, its main priority is
maintaining a record of the transaction of money and items.
With a buy, an item is lost and its price is added to the store balance.
Similarly, If the manager was to accept a Supplier’s offer,
that items asked price would be subtracted from the store balance
and be added to the list of items on sale.
This allows the Store to have a constantly updated reference to check
the progress of the store.

2: [2]
INTRODUCTION
To make it implementable in the real world, I have ensured that:
(1) Data is stored in files and opened in binary mode for speed.
(2) The interface has been made interactive and user friendly.
(3) It has covered all possible threats to efficacy by means of
Intensive Exception Handling like:
(i) Invalid Entries by User
(ii) An Advanced Search that is NOT case sensitive.
(iii) And many others like:
Maintaining transfer of cash through sale and purchase of the store,
Maintaining Transfer of Data from Supplier Offer to Item On Sale, etc

3: [1]
THE LIST
This is a Tabular representation of the list of items on sale in the
store. The following 4 entities are displayed here.
 The Item number
 The Name
 The Age (in Years)
 The Cost
SPACING TOOL
There is a function
which is responsible
for the tabular
format of THE LIST.
1
THE HISTORY
2
This is a more detailed view of the items in THE LIST.
It not only gives the 4 entities in THE LIST but also shows the
history of the item and its significance in the past.
However, only a limited number of items can be seen at a time.
THE SEARCH
3 This allows users to search for an item, making it much easier
than going through the long list to find something specific.
The search allows us to narrow down the list by
 Providing Ranges in the Cost and Age
 A word search for Name and History.
THE 6 FACES OF THE CUBE
This is a more elaborate explanation of THE CUBE
and the various tasks that it performs.

3: [2]
I AM A CUSTOMER
Once the money transfer is complete:
 A bill for the user will be displayed.
 There will be an increase in the store balance.
 The item will be removed from THE LIST.
4
I AM A SUPPLIER
5 The user will have to enter the details of the item
he wishes to sell including the price he is asking for
it. This will be stored and decided later by the manager.
I AM THE MANAGER
6
This option is for the manager. Since this is restricted to the
general public, it is password protected.
The Manager has the most number of options. He can add,
delete and edit an item on THE LIST. He can change the
password and access the CUBE CASHIER.
THE 6 FACES OF THE CUBE
This is one of the 3 user specific options.
If this is chosen, the user will be able to choose and buy the item
of his choice.
CUBE CASHIER
This is a money organizer
for the store. When an
item is sold or bought by
the store, the balance
increases and decreases
accordingly.
This option is for those who have something
to sell to the store.
When the manager accepts:
 The item will be added to the LIST.
 There will be a decrease in the store balance.

There are a number of possibilities to make this software better.
After learning the usage and application of graphics, I plan on further
improving the interactive nature of the software. The menu would have
clickable buttons rather than typed in choices and by introducing the
mouse pointer, selection of those options would be far more convenient.
I also intend on introducing selective functionality through user
accounts. This would provide more options for suppliers and managers.
A Supplier can make an account, send an offer and be updated on the
manager’s decision as well. This would be possible only with user
accounts where the supplier can be identified by their username. Also, if
the store is run by more than one person and each person is assigned a
specific task to play, user accounts will be able to divide the manager
options accordingly.
As of now, its functions are restricted to those of an Antique Store. I
plan to generalize it so that it can be used in any type of store allowing
the manager to choose which fields and options are most suitable for his
store.
The next thing would be to encrypt the data files. Presently, the files
store the details of the items on sale, the balance of the store and the
password to access the manager options. These can be easily accessed
using a notepad in windows. To prevent this, the files should be
encrypted so that those who do try to read the data will not be able to
make sense of it, and making the files Read Only can prevent offenders
from changing the information.
Unfortunately, this software is mainly just recording changes in the
store with transactions. With much further study, I can implement it in
the real world. Rather than recording the money moving from one
account to another, the software can be made to access the bank
accounts and allow the transaction of actual money.
