Data Dictionary – AI Powered Metadata Documentation

The Challenge

Enterprises run on data, but much of it sits in undocumented or poorly documented databases across multiple platforms. Creating data dictionaries manually is tedious, error-prone, and takes weeks of effort. Without proper documentation, analytics teams, compliance officers, and new employees struggle to understand what data means, how it should be used, and whether it meets governance standards. This slows down data initiatives, increases compliance risks, and makes enterprise data harder to discover and trust.

Our Solution

We built the Data Dictionary, an AI-powered platform that automates metadata documentation and profiling. It connects directly to multiple enterprise databases – SQL Server, MySQL, PostgreSQL, BigQuery, Redshift, Oracle, and Snowflake – extracts schemas, tables, and column-level details, and generates human-friendly documentation with AI-driven descriptions. The platform also profiles sample data to provide quality insights, and allows seamless export in multiple formats (Excel, PDF, Markdown, DOCX, JSON, Google Sheets).

Key Outcomes

• Undocumented databases transformed into searchable, AI-generated documentation.
• Weeks of manual documentation reduced to hours.
• Compliance-ready metadata with consistent, error-free reporting.
• Faster onboarding and migrations with clear data dictionaries available on demand.

Benefits for Enterprises

• Saves significant time and reduces errors in metadata management.
• Improves compliance posture by automating governance documentation.
• Makes data assets discoverable, understandable, and usable for all teams.
• Integrates seamlessly with modern cloud and enterprise data ecosystems.

Technical Foundation

The Data Dictionary is powered by a modern, AI-driven stack:

• Backend: Python, FastAPI, LangChain, Pandas, ydata-profiling
• Database Connectors: SQL Server, MySQL, PostgreSQL, Oracle, Redshift, Snowflake, BigQuery
• Frontend: React + Vite with Google OAuth authentication
• LLMs: OpenAI, Anthropic, Groq, HuggingFace
• Export Services: ReportLab, python-docx, Excel, JSON, Google Sheets integration

By turning undocumented systems into well-documented, AI-enhanced assets, the Data Dictionary accelerates cataloging, reduces compliance risks, and makes enterprise data accessible to everyone.
