What is a real-time database?
A real-time database is a system using real-time processing to handle ever-changing workloads. Real-time databases are traditional databases that are used in fields such as banking, law, medical records, multimedia and science. A stock market is an example of a real-time database because it is dynamic and changes rapidly.
The term real-time database applies to databases that handle data streaming in real time, including in-memory data grids, in-memory databases, NewSQL databases, NoSQL databases and time-series databases.
One of the benefits of a real-time database is being able to store data that enriches streaming data. A real-time database also enables continuous queries to process ongoing events from people, apps and machines. Instead of the data growing stale, it can be used immediately.
