Rbdb

Simple in memory database for Ruby

Installation

Add this line to your application's Gemfile:

gem 'rbdb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rbdb

Usage

require 'rbdb'

db = Rbdb.create_db('app')    # Create a DB
table = db.create_table('people')       # And a table
table.fields = {name: :string, age: :integer}      # Assign it a schema like field (Hash)
table.insert({name: 'John', age: 31})              # Give it some records
table.insert({name: 'Doe', age: 31})
table.find_all({age: 31})
=> [{:name=>"John", :age=>31, :id=>1}, {:name=>"Doe", :age=>31, :id=>2}]

Rbdb automatically assigns a unique id to each record inserted.
