🕒 00:25–01:30
🏷️ Labels: Network Analysis, Sql Optimization, Email Setup, Python, Data Visualization
📂 Project: Dev
⭐ Priority: MEDIUM
Session Goal:
The session aimed to enhance email communication analysis using network graphs and optimize SQL query performance for database management.
Key Activities:
- Email Handler Setup: Configured Firefox to use Gmail as the default email handler for
mailto:links. - Dataset Management: Notified of dataset reset, requiring re-upload for network analysis.
- Network Analysis: Utilized NetworkX to create a directed email network, filtered bidirectional communications, and refined graph visualization by removing self-loops and improving layout.
- Error Handling: Identified and resolved an undefined variable issue in the graph analysis code.
- Data Extraction: Converted bidirectional graph edges into a pandas DataFrame.
- SQL Optimization: Implemented strategies for SQL query performance improvement, focusing on batch inserts and indexing.
- Batch Insert Method: Developed a SQL script for batch inserting email details using loop-based and CTE approaches.
Achievements:
- Successfully configured email handling in Firefox.
- Completed initial steps in email network analysis and SQL query optimization.
Pending Tasks:
- Re-upload the dataset for continued network analysis.
- Further refine SQL scripts for enhanced database performance.
