 **Bookings** is a web application written in [ReactJS](https://reactjs.org) and [NodeJS](https://nodejs.org) that, backed by the power of the [MariaDB Node Connector](https://github.com/MariaDB/mariadb-connector-nodejs) and the [MariaDB X4 Platform](https://mariadb.com/resources/blog/deploying-mariadb-platform-x4/#smart), unleashes the power of [smart transactions](https://mariadb.com/resources/blog/introducing-mariadb-platform-x4-smart-transactions-and-cloud-native-storage/) on hundreds of millions of records with sub-second query performance without having to add any indexes!

 [MariaDB platform](https://mariadb.com/products/mariadb-platform/) unifies [MariaDB TX (transactions)](https://mariadb.com/products/mariadb-platform-transactional/) and [MariaDB AX (analytics)](https://mariadb.com/products/mariadb-platform-analytical/) so transactional applications can retain unlimited historical data and leverage powerful, real-time analytics in order to provide data-driven customers with more information, actionable insight and greater value – and businesses with endless ways to monetize data. It is the enterprise open source database for hybrid transactional/analytical processing at scale.
