# Personal AI Infrastructure — Database Management Module

**Version**: v1.1.9 | **Status**: Active | **Last Updated**: March 2026

## Overview

The Database Management module provides database lifecycle operations — schema management, migrations, connection pooling, and query execution for SQL and NoSQL backends.

## PAI Capabilities

- Connection pool management for multiple databases
- Schema migration planning and execution
- Query building and execution with parameterization
- Database backup and restore operations
- Health monitoring and performance metrics

## Key Exports

| Export | Type | Purpose |
|--------|------|---------|
| Connection managers | Various | Database connection pooling |
| Migration engine | Various | Schema versioning and migration |
| Query builders | Various | Safe parameterized queries |

## PAI Algorithm Phase Mapping

| Phase | Database Management Contribution |
|-------|-----------------------------------|
| **OBSERVE** | Query databases for current state and schema information |
| **BUILD** | Generate migration scripts for schema changes |
| **EXECUTE** | Run migrations, execute queries, manage connections |
| **VERIFY** | Validate schema integrity and migration results |

## Architecture Role

**Service Layer** — Consumed by `agentic_memory/` (persistent storage), `serialization/` (object persistence), and `api/` (data backend).

## MCP Tools

This module does not expose MCP tools directly. Access its capabilities via:
- Direct Python import: `from codomyrmex.database_management import ...`
- CLI: `codomyrmex database_management <command>`
