This project aims to facilitate collaborative engagement among team members in crafting a basic database capable of addressing inquiries related to a specific topic. Select a project theme appropriate for a database application. Options include, but are not limited to, health care systems, inventory control, education, manufacturing, and industry-specific projects. Once you've settled on your chosen topic, assemble a project report comprising the following components: a. Briefly explain your topic and state member-task responsibilities. b. Design an E-R diagram based on your project topic. - There must be at least five strong entities in your diagram. c. Write necessary CREATE TABLE statements (including constraint definitions) for all relations in your schema. d. Write 5 different INSERT INTO statements for each of your tables. e. Write 12 different SQL queries with their descriptions for the database you created. You must write the queries based on the specified approaches below: - 3 joins (with conditions) - 3 nested\sub-queries - 3 set operations - 3 aggregate operations (must include joins)
