The Painters

Mr. has been in the business of painting for almost more than a year. He runs his business with the name of "The painters" in Al-Ain. Although his primary area of services is painting, but Mr. X also gives decoration services for the houses. Due to the nature of his small business he could not afford to hire many people working for him, therefore he just have one person to assist him. Miss Y is responsible for maintaining the complete business records for "The Painters".

Most of the time, Mr. X gets his customers from referrals. It's very embarrassing and confusing sometimes when a customer calls and say that he/she has been referred to The painter from so and so customer, who got the services from The Painters last year. It gets even more complicated when the customer calling says that h./she wants exactly the same services which were given to so and so customer last year. Miss Y is maintaining the records of all the customers for the business, but each time to look for the customer who might have referred the new customer, to look for the exact nature of the services given is difficult and highly time consuming. Besides, most of the time Mr. X has to ask the customer calling about the address of the customer who has referred him to The Painters.

To overcome this problem Mr. X consulted a recent MIS graduate from UAEU, Asma Ahmed. After listening Mr. X business problem she advised him to maintain a Data base for his business. Mr. X agreed to Asma after her highly convincing consultancy and they both had a detailed sitting with together to learn about the business processes which are as follows:
