Apache Derby 10.16 API Documentation
Apache Derby is a standards-based, pure-Java relational database engine. Its easy-to-use data manager requires no administration by end users. Derby runs on any JVM at Java version 9 or higher and Derby supports JDBC version 4.3. Derby's platform-independent database format may be copied to any file system.

Information on Derby configurations follows.
Derby's modules may be wired together in several configurations. The modules are:
|Module name||Jar file||Description|
|org.apache.derby.engine||derby.jar||The embedded database engine contains Derby's core functionality. It contains its own JDBC driver, allowing one JVM to host both Derby and the applications which use it.|
|org.apache.derby.server||derbynet.jar||The network server wraps the database engine, enabling networked JDBC access.|
|org.apache.derby.client||derbyclient.jar||The remote JDBC client connects to a server across a network.|
|org.apache.derby.tools||derbytools.jar||Basic tools include a schema dumper and an interactive SQL interpreter.|
|org.apache.derby.optionaltools||derbyoptionaltools.jar||Optional tools support metadata introspection and access to other vendors' databases.|
|org.apache.derby.runner||derbyrun.jar||The runner module supports easy command-line administration of Derby installations.|
|org.apache.derby.commons||derbyshared.jar||The commons module contains cross-module support utilities.|
|org.apache.derby.locale_*||derbyLocale_*.jar||Message localizations support human-readable diagnostics in languages other than English.|
|org.apache.derby.tests||derbyTests.jar||An extensive body of tests stresses functionality in all of the other modules.|
The following conventions apply to the module diagrams presented here:
- Derby modules appear in blue.
- JVM modules appear in black.
- 3rd party modules appear in pink.
- Optional modules appear in gray.
