Document-Oriented Data Design with RavenDB

This workshop is designed for developers who have some experience with relational (SQL) databases and would like to learn how to handle data modeling in document-oriented NoSQL databases.
Document-Oriented NoSQL databases have great potential to provide flexibility, scalability and performance for their users. The first step to fulfill this potential is building the "foundation" - planning the way we would store data in a very different database from the
traditional SQL.

In this workshop, participants will learn the theory and the practical knowledge required for
modeling data for a scalabale and performant database.
