CONTRACTS: Add Attendance Analytics Functions

[truthixify]

Description

Implement analytics functions for attendance data including time tracking, frequency analysis, and reporting capabilities directly in the smart contract.

Files to Modify

• contracts/manage_hub/src/attendance_log.rs - Add analytics and reporting functions
• contracts/manage_hub/src/lib.rs - Add analytics endpoints
• contracts/common_types/src/types.rs - Add analytics data structures
• contracts/manage_hub/src/types.rs - Add attendance summary structures

Key Changes Required

1. Analytics Data Structures - Create structures for attendance summaries, statistics, and reports
2. Time-Based Queries - Implement functions to query attendance by date ranges and time periods
3. User Statistics - Add functions to calculate individual user attendance patterns and statistics
4. Aggregate Functions - Implement attendance frequency, duration, and pattern analysis
5. Performance Optimization - Design efficient data structures and queries for large attendance datasets
6. Reporting Functions - Add functions to generate attendance reports and summaries

Acceptance Criteria

• Add get_attendance_summary function with date range filtering
• Implement time-based attendance queries (daily, weekly, monthly)
• Add attendance frequency calculations per user
• Create user attendance statistics (total hours, average daily attendance)
• Implement date range filtering for all analytics functions
• Add performance optimizations for large datasets
• Include attendance pattern analysis (peak hours, days)
• Add attendance report generation functions

Hi Maintainer,

I would like to work on Issue #424: Add Attendance Analytics Functions.

I have experience building analytics and reporting modules for large datasets, designing efficient data structures, and creating performant query functions. This aligns with the task of implementing attendance statistics, time-based queries, and reporting capabilities directly in smart contracts.

For this task, I plan to:

• Add analytics data structures for attendance summaries, statistics, and reports.
• Implement time-based queries (daily, weekly, monthly) and date-range filtering for all functions.
• Compute user attendance statistics including total hours, average daily attendance, and frequency patterns.
• Implement aggregate and pattern analysis for large attendance datasets, such as peak hours and peak days.
• Add reporting functions to generate attendance summaries for users and admin dashboards.
• Optimize performance for smart contract storage and queries on large datasets.

I will follow the project’s existing coding conventions and ensure all analytics endpoints are efficient, accurate, and well-tested.

Hi, my name is Zarcc. I have reviewed the attendance analytics functions issue and understand the requirements. I am a fullstack developer with years of backend experience and 2 years of web3 experience, specializing in smart contract development, Rust, and blockchain optimization.

For this implementation, I will create analytics data structures for attendance summaries and statistics in common_types, implement time-based query functions supporting daily/weekly/monthly ranges in attendance_log.rs, add user statistics calculations for total hours and attendance patterns, build aggregate functions for frequency and duration analysis with efficient data structures, implement date range filtering across all analytics endpoints, optimize queries for large datasets using indexed lookups and batch processing, and add reporting functions generating comprehensive attendance summaries. I'll write extensive tests covering all analytics functions, edge cases, date range queries, and performance benchmarks. I can complete this within 4 days. Please assign this issue to me.
