Best NoSQL Databases for IoT Applications: Commercial and Open Source

The Internet of Things (IoT) requires certain database characteristics. IoT encompasses a wide range of technology from smart objects to empowering RFID systems. Astoundingly, the IoT worldwide revenue is $34.8 billion and growing. The challenges of using a NoSQL database for IoT come more from the development process than from the database itself.

Some developers get lulled into thinking they’ll put all the necessary data into a NoSQL database and figure out the schema later. But if you don’t create some form of structure for your data even within NoSQL, you risk the following challenges.

1. Data loss
2. Poor data readability
3. Pipeline inefficiencies

The extreme flexibility of NoSQL is a great advantage, but it can become a disadvantage if you don’t plan how to use the data. 

Key Considerations When Selecting an IoT Database

When building an IoT application, you should consider these important factors in the database you select.

1. Size, scale, and indexing capabilities
2. Stream processing
3. Flexible schema
4. Running querying support
5. Sliding window
6. Cost

But you’ll also want to think about the types of data you’ll be dealing with. Some examples of data types include.

1. Log data
2. RFID, geologic
3. Identifiers or addresses
4. Sensor data
5. Much, much more

InfluxDB

InfluxDB is another option that launched within the last decade. It was published in 2013 and is a key-value database. It uses the Go programming language and is optimized to handle time-series data. It has many IoT benefits, including:

• Indexable series
• Built-in linear interpolation for missing data
• Calculates aggregates based on continuous queries
• SQL-like query language to help automate data downsampling

MongoDB

MongoDB is another NoSQL database option. It is free and open-source and is a document-based database. You can store all types of data and analyze it in real-time. Additionally, developers enjoy how they can change the schema as needed.
