Entity – Relationship Diagram.
Using the following business case assumptions – create an E-R diagram with cardinality and conditionality that would satisfy these requirements.
A company has a number of employees. The attributes of EMPLOYEE include Employee_ID (identifier), Name, Address and Birthdate. The company also has several projects. Attributes of PROJECT include Project_ID (identifier), Project_Name, and Start-Date.
Each employee may be assigned to one or more projects, or may not be assigned to a project. A project must have at least one employee assigned and may have any number of employees assigned. An employee’s billing rate may vary by project and the company wishes to record the applicable billing-Rate for each employee assigned to a particular project.
