Top 5 Real Time Databases

A real-time database is one of the most vital prerequisites for agile application development, deployment, and management. While there are many robust database options out there, choosing the one with the right features can be vital. Take a look at some of the best real-time database options given below.

What is a Real-Time Database?

A real-time database[1] refers to a database system that relies on real-time processing for managing workloads with frequent state changes. It is different from conventional databases that usually work with persistent data that does not often change with time. Real-time databases find use in all applications that require instant real-time data updates based on changes and tracking of data.

This type of database is a vital requirement for taking instantaneous decisions. One of the key features of a real-time database is real-time processing, which helps process transactions or changes and enables acting upon them without delay. These databases are utilized by many industries and use cases such as law, accounting, medical records, banking, reservation systems, multimedia, and data analytics.

A real-time database is fundamentally a conventional database with the added ability to produce real-time responses. It makes use of timing constraints for representing specific value ranges for which the provided data qualifies. Compared to a real-time database, a traditional database is unable to work in circumstances where there are prevalent differences between real-world objects and their representative data.

A real-time database is considered a useful system for managing and processing time-sensitive queries, returning valid temporal data, and facilitating priority scheduling.

Advantages of using a real time database

Here some advantages of using a real-time database. Not necessarily all features described below are available in all real-time systems, but it provides a comprehensive view of this database implementation’s benefits.

  • Time Updates in Real Time

Real-time databases can synchronize data with every change while data update across interfaces is being updated through requests. Any implemented changes are reflected in real-time across any device being used for retrieving data.

  • Offline Synchronization

Offline synchronization is one of the key advantages of using a real-time database. Features like local disk data saving facilitate this, and once the server goes back online again, any changes implemented get synchronized with the server’s current state.

  • Splitting and scaling data

A real-time database enables users to split their available data across different databases within a project. They can also establish tiles for all database instances. 

  • Multiple device access

A real-time database enables users to access application data from multiple devices and interfaces, including app mobile and web devices. This is one of the most important reasons why many businesses choose real-time databases.

  • Affordable options

Developers and business owners rely on real-time database options as they are also quite affordable. Many companies offer flexible pricing, and what you have to pay depends on connections and the amount of data stored or downloaded.
