apache derby introduction

Apache Derby is an open-source, Java-based relational database management system (RDBMS) that provides a small footprint database engine that can be embedded within Java applications, or run as a standalone server. It was originally developed by IBM as the Java DB and was later donated to the Apache Software Foundation where it is now an Apache top-level project.

Derby is written in Java, which means that it is platform-independent and can run on any operating system that supports Java. It supports the SQL-92 and SQL-99 standards, which means that it can be used with any software that supports these standards.

Derby supports transactions, which means that it is capable of ensuring that data is consistent and durable. It also provides a range of security features, including user authentication and authorization, which can help to ensure that only authorized users have access to the data.

One of the key benefits of Apache Derby is its small footprint, which makes it an ideal choice for embedded applications where resources are limited. It is also easy to set up and use, which means that developers can quickly get up and running with it.
