Guys first we need to identify to Entities and its Attributes. Then the diagram will be easy. I think these will be entities and its attributes.

Entities can be thought of as nouns.

Entities

  • Website
  • Employee
  • Project

Attributes

  • Login
  • Info
  • Salary
  • Loan
  • Attendance

Correct me If I am wrong?

Right

I think there will be 2 more attributes of Project.

kon sy 2 or aayn gy?
