Draw an ER diagram. Make sure each entity type has at least one key attribute. Document any assumptions you make. Avoid diagrams with a single entity. b.if you think the description is incomplete, list other data the database should store. c.Adjust your design to incorporate these additions. Problem:A psychological study requires participants to answer several questions related to their personality. The database should store the multiple-choice answers (A, B, C, D) to the questions and information about each participant, such as participant id, age, and gender. The database should compute a score based on the individual's answers. The score indicates one of 8 personality categories. Each category has an identifying name and specifies that each of three qualities is either true or false. Draw an ER diagram. Make sure each entity type has at least one key attribute.
