Database

Requarks is using the NoSQL engine MongoDB as its database.

What is MongoDB?

MongoDB is cross-platform, open-source and highly scalable. MongoDB avoids the traditional table-based relational database structure in favor of JSON-like documents with dynamic schema. It is the most widely used document store engine in the world.

Manual Installation

1. Download MongoDB
2. Follow the installation guide for your platform.
3. Start the mongo client (mongo.exe on windows)
4. Create a new user with dbOwner role by running the following commands:

Mongo Shell

# Replace <database> in the command below:

use <database>

# Replace <name> and <password> in the command below:

db.createUser({ user: "<name>", pwd: "<password>", roles: ["dbOwner"] })

5. That's all folks!

Cloud-based Solutions

Various cloud providers are offering MongoDB as a service, such as:
