1. 3C is a consulting company in Newark. It needs a database to keep track of the assignment of employees to projects. For each employee, 3C wants to record an employee ID (unique for every employee), name, address, and birthday. For each project, 3C wants to record a project ID (unique for each project), project name, and start date. Employees are included in the database even when they have not been assigned to any project. A project must have at least one employee assigned. An employees billing rate may vary by projects, and 3C wishes to record the applicable billing rate for each employee when assigned to different projects.
