Requirement Analysis

A process that determines the user expectations for a software product is called requirement analysis. In software engineering, requirement analysis is known as requirement engineering. It involves communication with end-users and stakeholders to determine whether the system or software requirements are validated, conflicts are solved, and key requirements are documented. The first activity of the Software Development Life Cycle (SDLC) is requirement analysis.

Question

Create an E-R diagram for a medical clinic as follows:
a) A patient can make many appointments with one or more doctors in the clinic, and a doctor
can accept appointments with many patients. However, each appointment is made with only
one doctor and one patient.
b) With each appointment (once it takes place), the patient's records are updated to provide a
medical history. A visit may create multiple patient records each to include a diagnosis and
treatment.
c) Once an appointment is completed, the patient gets a bill. The bill may be paid in many
installments and a payment may cover more than one bill.
d) Bills are paid by either the patient or an insurance company, and are often paid by both

Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common. Make sure you show entities, relationships, cardinality, and optionality.
