Generate Database Architecture Diagrams in Seconds

Whether you're designing a new data layer or documenting an existing one, describe your database architecture in natural language and get a professional diagram instantly.

The challenge

Modern applications rarely use a single database. A typical system might have a primary PostgreSQL for transactional data, Redis for caching and sessions, Elasticsearch for search, and a data warehouse for analytics. Add replication, read replicas, failover, and connection pooling, and the data architecture becomes complex fast. Communicating this clearly to your team is critical for reliability, but drawing it all out manually is tedious.

The solution

Describe your database architecture naturally:

"The application connects to PgBouncer for connection pooling. PgBouncer routes to a primary PostgreSQL instance that replicates to two read replicas across availability zones. Application reads are split between the primary and replicas using a query router. A Redis cluster handles session storage and caching with automatic failover. Change data capture streams from PostgreSQL to Kafka, which feeds into a Snowflake data warehouse for analytics. Backups go to S3 with point-in-time recovery enabled."

The AI generates a clear diagram showing every database, data flow, replication path, and backup strategy. Iterate with chat-based editing to add monitoring, adjust replication topology, or include migration paths.

Database patterns we support

Primary-replica replication
Write-ahead log replication with read replicas, automatic failover, and connection pooling for high-availability deployments.
Polyglot persistence
Multiple database types serving different needs - relational for transactions, document stores for flexibility, graph databases for relationships, time-series for metrics.
Sharding and partitioning
Horizontal scaling with hash-based or range-based sharding, shard routers, and cross-shard query strategies.
Data pipeline architecture
CDC streams, ETL/ELT pipelines, data lakes, and warehouse ingestion from operational databases to analytics platforms.

Perfect for

Database design reviews and capacity planning
Data migration and modernization projects
Disaster recovery and backup documentation
Performance optimization analysis
Data pipeline architecture diagrams
Cloud architecture best practices

Frequently asked questions

How do I create a database architecture diagram?

Describe your databases, replication topology, caching layers, and data flows in plain English. ArchitectureDiagram.ai generates a professional diagram showing every database instance, connection pool, replica, and backup path in seconds.

What should a database architecture diagram include?

Include primary databases, read replicas, connection poolers (PgBouncer, ProxySQL), caching layers (Redis, Memcached), replication arrows, failover paths, backup destinations, and any CDC or ETL pipelines feeding downstream systems.

How do I diagram database replication?

Show the primary instance with directional arrows to each replica, labeled with the replication type (synchronous or asynchronous). Include the failover mechanism and any connection routing that directs reads to replicas and writes to the primary.

What is polyglot persistence and how do I diagram it?

Polyglot persistence means using different database types for different needs - PostgreSQL for transactions, Redis for caching, Elasticsearch for search, and a warehouse for analytics. Diagram each database with its specific use case labeled and show how data flows between them.

How do I visualize database sharding in a diagram?

Show the shard router or application layer directing queries to specific shards based on the sharding key. Include multiple shard nodes, label the sharding strategy (hash-based, range-based), and show any cross-shard query coordination.
