Agenda cont..

Royal book shop in Ambalangoda still uses a conventional system for

their transaction and inventory control. Even though the Book Shop

runs in large scale, manual system gets the business down.

- It requires more space, time, labour and stationery

- It is Slow and less security.

- It is difficult to update data and retrieve details

important to improve its quality by giving the chance for the customer

to order books online.
