Apache Derby is a pure Java relational database engine using standard SQL and JDBC as its APIs. More information about Derby can be found on the Apache web site. Derby functionality includes:

Embedded engine with JDBC drivers
Network Server
Network client JDBC drivers
Command line tools: ij (SQL scripting), dblook (schema dump) and sysinfo (system info)

This is a feature release. The following new features were added:

Definer's rights - Procedures and functions can now run with their creators' privileges, rather than with the current user's permissions.
BOOLEAN data type - Boolean is now a legal data type for columns, routine arguments, and function return values.
Table truncation - A new TRUNCATE TABLE command drops all rows in a table quickly.
Query plan browsing - A new PlanExporter tool helps developers visualize query plans better.
Unicode database names - Remote clients can now use database names which include Unicode characters outside the ASCII codeset.

It is essential that you verify the integrity of the downloaded files using the PGP and MD5 signatures. MD5 verification ensures the file was not corrupted during the download process. PGP verification ensures that the file came from a certain person.

The PGP signatures can be verified using PGP or GPG. First download the Apache Derby KEYS as well as the asc signature file for the particular distribution. It is important that you get these files from the ultimate trusted source - the main ASF distribution site, rather than from a mirror. Then verify the signatures using ...

% pgpk -a KEYS
% pgpv db-derby-X.Y.tar.gz.asc

or

% pgp -ka KEYS
% pgp db-derby-X.Y.tar.gz.asc

or

% gpg --import KEYS
% gpg --verify db-derby-X.Y.tar.gz.asc

To verify the MD5 signature on the files, you need to use a program called md5 or md5sum, which is included in many unix distributions. It is also available as part of GNU Textutils. Windows users can get binary md5 programs from here, here, or here.

We strongly recommend that you verify your downloads with both PGP and MD5.
