RafaA system flow diagram visually represents the flow of information through a system, showing the processes involved and the interactions between different components. It helps in understanding the logic and sequence of operations within a system, making it easier to identify bottlenecks or inefficiencies. System flow diagrams are often used in software development, business process analysis, and system design.

What is context diagram of enrollment system?
A context diagram of an enrollment system typically shows the system as a central entity, surrounded by external entities such as students, administrators, courses, and possibly databases. It illustrates the interactions between the system and its external entities, without detailing the internal workings of the system.
What is the ER diagram of a school management system?
An ER diagram for a school management system typically includes entities such as Student, Teacher, Course, Classroom, and Enrollment. Relationships between these entities can be depicted using cardinality and participation constraints to show how they are connected (e.g., a student enrolls in courses taught by teachers in specific classrooms). The ER diagram serves as a visual representation of the database schema for the school management system.
ER Diagram of transport system of college?
An ER diagram of a college transport system would typically include entities such as Student, Driver, Vehicle, Route, and Booking. Relationships between these entities would show how students book rides, assign drivers to vehicles, and track routes taken. Attributes for each entity might include student ID, driver license number, vehicle number, route ID, and booking timestamp.
What are the differences between a use-case diagram and use case?
A use-case diagram is a visual representation of the interactions between actors and the system, showing how users interact with the system to achieve goals. A use case is a description of a specific interaction between a user and the system to accomplish a goal. Use cases are typically detailed in text format and provide more specific information compared to the use-case diagram.
How do you draw an Er diagram on school management system?
To draw an ER diagram for a school management system, you would first identify the entities involved (e.g., students, teachers, classes). Then, you would define the relationships between these entities (e.g., a teacher teaches a class, a student enrolls in a class). Finally, you would represent these entities and relationships using symbols like rectangles for entities and lines connecting them to show relationships. There are many software tools available that can help you create ER diagrams easily.
