Please tell me what is entities and attributes ?? with some examples!
Entities and Attributes: The basic object that the ER model represents is an entity, which is a thing in the real world with an independent existence. An entity may be an object with a physical existence
(for example, a particular person, car, house, or employee) or it may be an object with conceptual existence (for example, a company, a job, or a university course). Each entity has attributes-the particular properties that describe it. For example, an EMPLOYEE entity may be described by the employee’s name, age, address, salary, and job. A particular entity will have a value for each of its attributes, the attribute value that describe each entity become a major part of the data stored in the database.
