Databases rely on specific ports for storage access, replication, cluster communication, and API-level queries. This dataset covers SQL Server, MySQL/MariaDB, PostgreSQL, MongoDB, Cassandra, Redis, and Elasticsearch—ranging from relational databases to distributed and in-memory engines.
Perfect for architects designing application tiers, securing East-West traffic, and troubleshooting API or replication failures.
