Attendance Management

Problem Statement

Organizations need a robust system to track and manage the attendance of individuals across various contexts (e.g., events, classes). This system must handle diverse scenarios, ensure accuracy, and support contextual data.

Approach

To address these needs, we propose a centralized database to record attendance, which accommodates a variety of data points including user details, attendance status, and related metadata. This system will be designed to support scalability and flexibility in terms of different attendance contexts.

Solution

The solution involves the implementation of a comprehensive attendance management system encapsulated within a microservice architecture. This system will allow for real-time tracking of attendance data, provide insights through analytics, and offer the flexibility to integrate with other systems via APIs.

DB Design

Table: Attendance

The Attendance table is designed to store attendance records with contextual data and user information. Here is the schema for managing the database:
