# Outline ### Initiating Server `npm start` ## Mongodb We used [Mongodb](https://www.mongodb.com) which is a NoSql database. In the project we have configured it to used it with [mLab](https://mlab.com/) which is used as cloud database for both local and production enviroment by default. You can create your own mLab account and integrate it with your database by entering `connectionstring` in `olo-api/app.js` ## Express JS Express JS contains all the configuration details related to node server.
