Entity Relationship Diagram Software Engineering

Entity Relationship Diagram (aka ER Diagram, E-R Diagram, ERD) is a time-tested and widespread software development and software engineering method for data modeling, illustrating the logical structure of databases and system design. For ERDs construction are used three basic elements: entities, attributes, and relationships. Chen's notation for ERD supposes the use of rectangles (boxes) to represent entities and diamonds to depict relationships between first-class objects. This notation is popular when creating conceptual data models of information systems. Another standardized notation for ER diagrams is Crow's foot notation. ConceptDraw DIAGRAM as a powerful Entity Relationship Diagram software engineering provides the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park for instantly describing databases using ERDs of Crow’s Foot and Chen’s notations. Use the predesigned vector elements for both these notations from 2 libraries included to Entity-Relationship Diagram (ERD) solution.

This is ERD from the documentation of the High School Emergency Medical Responder (HS EMR) information system.
"Emergency medical responders are people who are specially trained to provide out-of-hospital care in medical emergencies. There are many different types of emergency medical responders, each with different levels of training, ranging from first aid and basic life support. Emergency Medical Responders have a very limited scope of practice and have the least amount of comprehensive education, clinical experience or clinical skills of EMS personnel. The Emergency Medical Responder (EMR) is not meant to replace the roles of Emergency Medical Technicians, Emergency Medical Technologists or Paramedics and their wide range of specialities. Emergency Medical Responders typically assist in rural regions providing basic life support where pre-hospital health professionals are not available due to limited resources or infrastructure." [Emergency medical responder. Wikipedia]

This analysis tool can help you focus your attention on the specific success factors that are right for your team.

(2) Weaknesses are those negative internal attributes that are working against your success. You can shore up those weaknesses so they don’t stop your success.
(3) Opportunities are those external conditions that can have a positive effect on your goals. These opportunities can point you in the right direction.
(4) Threats are those external conditions that can have a negative effect on your goals. These threats will affect you less if you can identify and minimize them. ...
