In this talk from the RavenDB conference, Elemar Júnior discusses the differences between relational and document databases — and how you can utilize RavenDB for best effect.
For the last 40 years or so, we used relational databases successfully in nearly all business contexts and systems of nearly all sizes. Therefore, if you feel no pain using a RDBMS, you can stay with it. But, if you always have to work around your RDBMS to get your job done, a document-oriented database might be worth a look.
RavenDB is a 2nd-generation document database that allows you to write a data-access layer with much more freedom and many fewer constraints. If you have to work with large volumes of data, thousands of queries per second, unstructured/semi-structured data or event sourcing, you will find RavenDB particularly rewarding.
In this talk, we will explore some document database usage scenarios. I will share some data modeling techniques and many architectural criteria to help you to decide where safely adopt RavenDB as a right choice.
