RavenDB is a document-oriented NoSQL database system which stores each document in JSON format.
It developed out of the lack of available document databases that would work on a Windows system without causing significant issues. While there are applications out there that deal with document databases, nothing was developed specifically for the .NET framework.
Getting Started: What Are Databases?
Databases are used to store and organize large amounts of data. There are many different types of databases but when it comes to software development, the most commonly used type is a relational database. Most relational databases use the SQL query language to access the data which is stored in predefined tables. The complexity of SQL databases led developers to find a simpler approach which gave rise to NoSQL databases.
What is a NoSQL Database?
NoSQL databases provide a simpler and faster way to organize an extremely high-volume of disparate data types. Instead of using predefined structures to store the data, which require taking the database offline to make changes, NoSQL databases allow programmers to add new data on the fly. There are different types of NoSQL databases, depending on which model they use to store data. One model of storing data is a document-oriented database such as XML or RavenDB. Others include key-value stores such as BerkelyDB, wide-column stores such as Cassandra, graph databases such as Neo4J, and more.
What Is a Document-Oriented Database?
A document-oriented database stores all data relating to a single object in a single document, typically in JSON or XML format. This makes mapping objects into the database a lot easier.
The man behind this database system is Oren Eini, an independent consultant who strives to promote quality software and reduce pain points in software development. Like many programmers and software developers who seek to expand their skills, Oren wanted to push his Erlang abilities further so he set out to read the CouchDB source code.
This piqued his interest in NoSQL. As a result, he began to implement his own document database. This was the first version of what became RavenDB, and things progressed naturally from there.
Once Oren realized that document databases could have a wider application and that .NET developers could benefit from it, he refined his initial idea and RavenDB was born. It's still a young project but brings a lot of benefits to the table for the .NET ecosystem.
RavenDB is open source and has a commercial license available. It comes with the following features:
- It includes a fully functional .NET and Java client APIs.
- It has trigger support that allows developers to do things like document merges, auditing, versioning, and authorization.
- It is scalable and secure.
- It runs natively on Windows.
- And it is built with performance in mind — the storage can handle up to 16 TB on a single machine.
Even though it is relatively young (the initial concept was developed around 2009), there are various resources available to help you get started with RavenDB. They include online resources, books, and a couple of online communities where you can ask questions and share your problems and solutions with others.
The following resources provide the list of official websites, documentation, and beginning steps.
