Course and Grades Database Schema
A database design for a school or university: students, courses, enrolments, assessments and grades, with the relationships between them.
Student Enrolment Workflow
The admission-to-enrolment journey at a college: application, document verification, merit list, fee payment and student ID.
Online Exam Proctoring Sequence
How a remotely proctored online exam runs: identity check, environment scan, the timed exam with AI monitoring, and review of flagged events.
Assignment Submission Lifecycle
The states of a student assignment: draft, submission before or after the deadline, plagiarism check, grading, feedback and resubmission.
Live Classroom Streaming Deployment
How live online classes are delivered to thousands of students: the teacher's stream, media servers, recording and a CDN for replays.
University ERP Architecture
A university ERP: admissions, student records, fees, timetable, exams, HR and payroll, library and hostels in one system.
