Design a database with the help of DBMS to keep track of information for an art museum. Assume that the following requirements were collected: The museum has a collection of art objects. Each art object has a unique identification, an artist (if known), a year (when it was created, if known), a title, an epoch (Renaissance, Modern, Ancient, etc.), and a description. The arts objects are classified in the museum in several ways as discussed below: Arts objects are categorized based on their type. The main types are: painting and sculpture, plus another type they called “other” to accommodate objects that do not fall into one of the two main types. A painting has a paint type (oil, watercolor, etc.), material on which it is draw on (paper, canvas, wood, etc.), and style (modern, abstract, impressionism, etc.). A sculpture has a material from which it was created (wood, stone, iron, etc.), height, weight, and style. An art object in the other category has a type (print, photo,…arrow_forward
