Introduction to RavenDB by Rob Ashton.
From the description:
In this session we will give a brief introduction to the concept of a document database and how it relates to what we already know before launching into a series of code demos using the RavenDB .NET Client API.
We will cover basic document structure, persistence, unit of work, querying / searching, and demonstrate real world use for map/reduce in our applications.
The usual (should I say expected?) difficulties with being unable to read the slides and/or examples in a video. Slides really should be provided with video presentations.
If you are interested in RavenDB, there are more presentations and blogs entries at Rob Ashton’s blog.
