This section describes how to download and install Java DB (Derby database server) 10.11 - free for evaluation.
Java DB is a relational database management system that is based on the Java programming language and SQL.
Java DB is a commercial release of the Apache Software Foundation's (ASF) open source relational database project.
But you can still download a copy of Java DB free for evaluation.
The Apache project is called Derby.
Java DB 10.11 free version is now included in the JDK package.
If you have already downloaded and installed JDK 1.8, the Java DB is available in
the %JAVA_HOME%\db folder. There is no need to download and install Java DB separately.
For example, on my Windows computer, I have JDK 1.8.0_45 installed.
The Java DB is located at "C:\Program Files\Java\jdk1.8.0_45\db\".
If you haven't installed JDK 1.8 yet. Please follow the JDK 1.8 download and installation tutorial
presented earlier in this book.
If you have an old version of Java DB (Derby) installed,
you should remove the old version and remove related environment variables.
For example, I have JAVA DB 10.5.3 installed. So I need to remove the
"C:\Program Files\Sun\JavaDB" folder and
the "DERBY_HOME=C:\Program Files\Sun\JavaDB\bin\.." environement variable.
