An art gallery wants to record data regarding its customers, artists and art projects.
The gallery may have multiple paintings of a particular artist at all times. Paintings may be sold and re-purchased more than one time by the gallery. In other words, the gallery can sell a painting and later on purchase the painting and resell it to the same or another customer.
