Code for session up at https://github.com/brunomlopes/ravendb-sql-saturday-porto-2014 RavenDb is a .NET document database with an HTTP REST API, Lucene based indexes, ACID read/writes and BASE queries that's been picking up steam in the .NET space. In this session we'll see the very basics of using RavenDB from a web application, including reads, writes and simple queries. We'll see how RavenDB uses LINQ and Lucene to create indexes similar to materialized views to provide fast query-time responses, and what are the main differences in modeling data and entities from the perspective of a developer used to relational databases.

persistence - where any decent sized
enterprise will have a variety of different data
storage technologies for different kinds of data.”- Martin Fowler, http://martinfowler.com/bliki/PolyglotPersistence.html, 2011
