Database Comparison Presentation with Rich Styling

Problem/Feature Description

A data engineering team at a logistics company is evaluating three databases for a new real-time analytics workload: PostgreSQL, ClickHouse, and Apache Druid. The team lead needs to present the tradeoffs to the CTO and VP of Engineering in a 15-minute slot. The audience is technical but time-pressed — they want crisp visual comparisons, not walls of text.

The presenter wants slides that show databases side-by-side (not just bullet lists), with key terms visually highlighted to draw attention to the most important distinctions. The presentation should also include a benchmark comparison showing query latencies, and use color coding to call out which option is fastest for each workload type.

The presentation will be delivered from the terminal. It needs to look polished and professional, with consistent colors throughout that work well in a dark terminal.

Produce a 7-8 slide presenterm presentation covering: why the team is evaluating, what each database offers, a direct comparison, and a recommendation.

Output Specification

Produce a single file db-comparison.md with the complete presentation, ready to run with presenterm. The file should demonstrate side-by-side content layout and colored/styled text elements.
