Reduce hardware costs by 50% and increase storage capacity
B
90% reduction in data entry time and sub-second query responses
C
Make the system compatible with all operating systems
D
Implement blockchain technology for security
Explanation

The project set specific performance targets: 90% reduction in data entry time, 100% elimination of duplicate data, real-time query response in less than 1 second, and support for 1,000+ concurrent users.

Methodology

## What was the systematic approach used in the project methodology?

A
Analysis, design, migration, interface creation, and validation implementation
B
Survey, prototype, testing, deployment, and maintenance

Explanation

The project followed a 5-step systematic approach: 1) Analyze current spreadsheet structure, 2) Design normalized database, 3) Develop migration tools, 4) Create query interface, and 5) Implement validation systems.

Schedule Complexity

## What makes school scheduling particularly complex for spreadsheet management?

A
Students being in multiple groups simultaneously with different affiliations
B
Spreadsheets have row and column limitations that schools exceed
C
Teachers frequently change their schedules without notice
D
Schools use different spreadsheet software that aren't compatible
Explanation

School schedules involve complex overlapping systems: students are in multiple groups (classes, English levels, tech tracks, clubs) simultaneously, with different temporal structures and 5+ simultaneous affiliations per student.

System Architecture

## What two main diagrams were created to show system architecture?

A
Data Flow Diagram (DFD) and Entity Relationship Diagram (ERD)
B
UML Class Diagram and Sequence Diagram
C
Network Topology Diagram and Security Architecture Diagram

Explanation

The project created a Data Flow Diagram (DFD) to show system workflow and an Entity Relationship Diagram (ERD) to show database structure. The DFD addresses data flow issues, while the ERD solves structural problems.

Database Design

## How many tables were designed in the database schema and what was the key principle?

A
8 tables with everything connecting through the People table
B
12 tables with centralized security management
C
17 tables with everything connecting through the Schedule Entries table
D
25 tables with distributed relationship management
Explanation

The database was designed with 17 normalized tables organized into three layers: Security Layer (top), Core Data (middle), and Connection Hub (bottom). The key principle is that everything connects through the central Schedule Entries table.

Functional Prototype

## What platform was used for the functional prototype and what commands did it support?

A
Web application with login, schedule view, and edit functions

Explanation

A Telegram bot was developed as the functional prototype, supporting commands like /whereis (find student location), /schedule (show daily schedule), and /tomorrow (display tomorrow's schedule), demonstrating query efficiency improvements.

Technology Stack

## Which technologies were used in the project implementation?

A
Python, SQLite, Telegram, Pandas, and Flask
B
Java, MySQL, WhatsApp, Spring Boot, and Hibernate
C
JavaScript, MongoDB, Facebook Messenger, Node.js, and Express

C#, SQL Server, Microsoft Teams, .NET, and Entity Framework
Explanation

The project used Python for programming, SQLite for the database, Telegram for the bot platform, Pandas for data transformation, and Flask for API integration and web framework.

Efficiency Comparison

## What was the query efficiency comparison between spreadsheet and database systems?

A
Spreadsheets: 5-10 minutes vs Database: less than 1 second
B
Spreadsheets: 1-2 minutes vs Database: 10-15 seconds
C
Both systems respond in similar time frames
D
Spreadsheets are actually faster for simple queries
Explanation

The manual spreadsheet method for finding a student's location takes 5-10 minutes across multiple files, while the database system provides responses in less than 1 second through optimized queries.

Future development includes: 1) Full system deployment replacing spreadsheets, 2) Parent/student web portal, 3) AI scheduling optimization, and 4) Analytics dashboard for data-driven insights.

Implementation Timeline

## What was the estimated timeline for full implementation?

A
3 months: migration, development, and optimization phases
B
6 months: research, design, development, testing, and deployment
C
1 year for complete system overhaul

Explanation

The project estimated a 3-month implementation timeline: Month 1 for data migration and system setup, Month 2 for portal development and staff training, and Month 3 for full implementation and optimization.

Data Flow Diagram

## What problems does the Data Flow Diagram (DFD) specifically address?

A
Centralized data flow, automated synchronization, and real-time validation
B
Network security, data encryption, and access control
C
