Derby Database

Apache Derby, also known as Java DB, is a relational database management system developed by the Apache Software Foundation. Derby is written in Java and is based on the Java, JDBC, and SQL standards.

#What is Derby?

Derby, also known as Java DB, is a relational database management system (RDBMS) developed by Apache Software Foundation. It is written in Java and is a portable, embeddable, and open-source database that can be used in various environments.

#Derby Key Features

Here are some of the most recognizable features of Derby:

  • Supports SQL-92 and SQL-99 standards and has a JDBC driver for connectivity.
  • Provides a small footprint, with the entire database system consisting of a single JAR file.
  • Has a modular architecture, allowing the user to add or remove features depending on their needs.
  • Offers a high level of data security and encryption.
  • Supports stored procedures, triggers, and functions, which can be written in Java or any other language supported by the Java Virtual Machine (JVM).
  • Supports various types of data including XML, binary data, and spatial data.

#Derby Use-Cases

Here are some common use-cases for Derby:

  • Development and testing of Java applications as it is bundled with Java Development Kit (JDK).
  • Web applications and Java EE environments where a lightweight, embeddable database is required.
  • Small-scale data management systems where portability and ease-of-use are important
  • Educational purposes: Due to its simple SQL interface and easy-to-use JDBC driver, Derby is often used in universities and other educational institutions to teach relational database concepts.

#Derby Summary

Derby is a lightweight, Java-based, embedded database engine that is highly portable and easy to use. It is ACID-compliant and supports the client-server architecture, making it suitable for a wide range of applications.
