Make Conceptual Model for the following scenario:

Mary Richards owns a house painting company. She has decided that she needs a better record-keeping system that can be used to quickly retrieve information about her current and former customers, such as their name and phone number. She already has detailed data about the individual jobs that her company has done for these customers, such as the job number, the beginning and end dates of the job, a brief description of the job, and the amount billed. However, Mary would like to be able to easily relate this data to the jobs customer and to her employees who worked on the job. Each job has a foreman and several other painters on it. She also has information about all of her employees (their SSN, their name, their salary and their phone number). Sometimes an employee will be a painter on one job and a foreman on another. When a customer calls with a complaint about the work being done on their house Mary needs to be able to determine who is or was the foreman on the job and who else worked on the job.

Often times customers are referred by other customers, Mary thinks it would be a good idea to store data about the referral sources. When a customer refers another customer Mary sends $10 to the referring customer with a thank you note. Mary doesnt recognize multiple referral sources for an individual customer and she has no interest in storing data on the self-referrals. Of course a customer may refer many other customers to Mary.
