Open Source Databases: Enablers for IoT Applications
With billions of devices generating trillions of bytes of data, it is crucial for
enterprises to be able to organise, store and work with all of it. In this context,
databases play a crucial role. The important parameters for choosing the right database for IoT applications are scalability, availability, the ability to handle huge amounts of data, high processing speed and schema flexibility, integration with varied analytical tools, security, and costs.

BigchainDB: A Popular and Powerful Database for Blockchain
Blockchain technology offers decentralised control, where no one has any ownership or control over the network; and a tamper-proof environment, where nothing gets deleted from network storage. It also has the ability to create and transfer assets on the network without reliance on a central entity. Blockchain storage, however, requires a powerful database, and this is where BigchainDB comes in.
