Documentation provides comprehensive written resources covering all aspects of Geode graph database, from introductory tutorials to detailed technical specifications. Well-organized documentation enables rapid learning, efficient problem-solving, and successful implementation of graph database solutions using Geode’s ISO/IEC 39075:2024 GQL-compliant architecture.

Documentation Philosophy

Geode’s documentation philosophy emphasizes clarity, completeness, and practical utility. Documentation serves multiple audiences with different needs: developers building applications, operators deploying production systems, contributors extending Geode itself, and decision-makers evaluating technology options.

Documentation Principles

Core principles guide documentation development:

Accuracy - All documentation reflects current implementation, verified against actual code and behavior. Documentation updates accompany code changes to maintain synchronization.

Completeness - Documentation covers all features, APIs, and operational procedures. Missing documentation represents incomplete features.

Clarity - Technical accuracy never sacrifices understandability. Clear explanations, concrete examples, and logical organization make complex concepts accessible.

Practical Focus - Documentation emphasizes practical application over theoretical discussion. Real-world examples, common patterns, and operational procedures take precedence.

Progressive Disclosure - Documentation structure supports different depth levels, from quick-start tutorials to detailed technical specifications. Readers access appropriate detail for their current needs.

Documentation Types

Different documentation types serve distinct purposes:

Tutorials provide step-by-step introductions for newcomers, teaching through concrete examples and hands-on exercises.

How-To Guides offer practical solutions to specific problems, focusing on accomplishing particular tasks.

Reference Documentation catalogs all features, APIs, and configuration options comprehensively and precisely.

Explanatory Documentation explores concepts, architecture, and design rationale, building deeper understanding.

Operational Guides cover deployment, configuration, monitoring, and troubleshooting for production systems.

MATCH (n:Person)-[:KNOWS]->(m:Person)
WHERE n.age > 30
RETURN n.name, m.name;

from geode_client import Client
import asyncio

async def main():
    client = Client(host="localhost", port=3141)
    async with client.connection() as conn:
        # Create node
        await conn.execute(
            "CREATE (n:Person {name: $name, age: $age})",
            parameters={"name": "Alice", "age": 30}
        )

        # Query node
        result, _ = await conn.query(
            "MATCH (n:Person {name: $name}) RETURN n",
            parameters={"name": "Alice"}
        )
        for row in result.rows:
            print(row)

if __name__ == "__main__":
    asyncio.run(main())

Tested Examples - All examples are tested against actual Geode instances to ensure correctness.

Annotated Examples - Complex examples include inline comments explaining key points:

-- Find friends of friends, excluding direct friends
MATCH (person:Person {name: 'Alice'})-[:KNOWS]->(friend)
  -[:KNOWS]->(fof:Person)
WHERE NOT (person)-[:KNOWS]->(fof)  -- Exclude direct friends
  AND fof <> person                  -- Exclude self
RETURN DISTINCT fof.name
ORDER BY fof.name;
