Apache Derby
Apache Derby is an open-source relational database implemented entirely in Java, formerly governed by the Apache Software Foundation (retired October 2025). It provides a small-footprint (~3.5MB) database engine with full SQL support, JDBC compliance, ACID transactions, stored procedures, and triggers. Derby operates in both embedded mode (bundled inside Java applications) and client/server mode via the Derby Network Server.
Apache Derby publishes 1 API on the APIs.io network. Tagged areas include Apache, Database, Embedded, Java, and JDBC.
The Apache Derby catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Apache Derby’s developer surface includes developer portal, documentation, getting-started guide, Stack Overflow tag, and 5 more developer resources.

Notable capabilities this provider offers.
Embedded Mode
Derby can be embedded directly in Java applications as a library, providing a zero-administration database with no separate server process required.
Client/Server Mode
Derby Network Server supports multiple concurrent JDBC clients connecting over TCP/IP using the Derby Network Client driver.
Full SQL Support
Supports ANSI SQL-92 with extensions including subqueries, joins, constraints, triggers, views, stored procedures, and user-defined functions.
ACID Transactions
Full ACID transaction support with row-level locking, MVCC-style isolation levels, and savepoints.
Small Footprint
The base Derby engine and embedded JDBC driver is approximately 3.5MB, making it suitable for desktop and embedded applications.
Java Stored Procedures
Supports Java-based stored procedures and functions callable directly from SQL using standard JDBC interfaces.

Use Cases 4
What developers build with this provider.
Embedded Application Database
Embed Derby in desktop Java applications, IDEs, or tools that need a local SQL database without a separate server.
Unit and Integration Testing
Use Derby as an in-memory or on-disk test database for Java application integration tests with JDBC.
Lightweight Development Database
Use Derby as a development database when production uses a heavier RDBMS, without installing MySQL or PostgreSQL.
Data Migration and ETL
Use Derby as a staging database for ETL processes in Java-based data pipelines.
Integrations 5
Pre-built integrations with other platforms and tools.
JDBC
Derby provides JDBC 4.0/4.1/4.2 compliant embedded and network client drivers.
Spring Framework
Commonly used with Spring DataSource and JPA/Hibernate for test database configuration.
Hibernate / JPA
Derby has a Hibernate dialect (DerbyDialect) for ORM integration.
Apache Maven
Derby artifacts are available on Maven Central under org.apache.derby group ID.
Eclipse IDE
Eclipse IDE includes Derby as a built-in SQL explorer and development database.
