Hi there, take a look at those standard libraries shipped with Ruby:

• PStore http://ruby-doc.org/stdlib-2.2.3/libdoc/pstore/rdoc/PStore.html
• JSON http://ruby-doc.org/stdlib-2.2.3/libdoc/json/rdoc/JSON.html
• YAML http://ruby-doc.org/stdlib-2.2.3/libdoc/yaml/rdoc/YAML.html

Advantage with PStore is that it handles the persistence for you, no need load a file, read or parse file contents. However it is not very hard to make your own little store.

You could actually look at this article that gives a bit more background: https://www.krautcomputing.com/blog/2015/09/21/rubys-built-in-databases-meet-pstore-and-yamlstore/

Thanks @ollie and @fappelman
