Mince is a ruby gem to provide a light weight ORM to persist data to a variety of databases in ruby apps.
The motivation behind this is so your application is not tightly tied to a specific database. As your application grows you may need to upgrade to a different database or pull specific models to a different persistence strategy.
Other ORMs are married to the Active Record Architecture Pattern. Although Mince can be used with the Active Record pattern as well, it is designed to be used in more of a Multitier Architecture Pattern, where the data layer is separated from the business logic layer in the application.

Currently only compatible with Ruby 1.9+. Support for Ruby 1.8 to come later.
This library contains the core components to use Mince supported database interfaces. These interfaces can be interchanged, but in this setup example we will be using HashyDb, which is an in-memory ruby hash database.
Install mince and hashy_db gems:
gem install mince hashy_dbUse the config class to configure which mince database interface you desire to use:
require 'mince'
require 'hashy_db'
Mince::Config.interface = Mince::HashyDb::Interface# Get the interface
interface = Mince::Config.interface
# Add a book
interface.add 'books', title: 'The World In Photographs', publisher: 'National Geographic'
# Get all books
interface.find_all 'books'
# Replace a book where the record's id is 1
# Use the interface's primary_key field because
# some databases use non `id` fields for the primary key
primary_key = interface.primary_key
interface.replace 'books', primary_key => 1, title: 'A World In Photographs', publisher: 'National Geographic'The following pages provide a deeper look into Mince
