Introduction
The group of recipes presented in this chapter deals with data persistence, either through a relational SQL database or a NoSQL database.
The first recipe describes how to access and modify data stored in a relational database, such as Oracle or MySQL. Groovy makes accessing data using the SQL language a very elegant affair, compared to the clunky Java's JDBC APIs.
