Entity (Report Builder 1.0)
An entity is a collection of related data. The data is organized into fields that uniquely identify an instance of the entity. For example, suppose your data source contains data about the employees in your company. Typically, this employee data would be grouped into at least one entity. One entity might be called Employees and it would contain data such as the employees' first and last names, home addresses, phone numbers, and emergency contact information. Another entity might be called Salaries and it would contain data such as the starting salary, job level, past bonus amounts, and current salary of each employee.
Here is another example, suppose you work for a large university. One entity might be called Students and it contains data such as each student's first and last name, address, and enrollment status. Another entity might be called Classes and it contains data such as the class name, instructor name, and the semester the class is taught. A third entity might be called Instructors and it contains data such as the instructor's first and last name, and the classes the instructor teaches. A fourth entity, called Registration, might contain data such as student, class, registration period and grade.
