Apache Derby (previously distributed as IBM Cloudscape) is a (retired) relational database management system (RDBMS) developed by the Apache Software Foundation that can be embedded in Java programs and used for online transaction processing. It has a 3.5 MB disk-space footprint.
Apache Derby is developed as an open source project under the Apache 2.0 license. For a time, Oracle distributed the same binaries under the name Java DB. In June 2015 they announced that for JDK 9 they would no longer be doing so. In October 2025 Derby developers voted to retire the project and stop supporting it.
