The Top 5 Free Real-Time Databases
Real-time databases are important prerequisites for the development, deployment, and management of cutting-edge applications. Developers and business owners alike rely on these databases’ functionality is crucial for many real-life applications.
While there are many premium real-time databases worth looking at, the free ones out there are also quite powerful. Your business can save costs and achieve its intended development outcomes with the right one. Read on to discover the top free real-time databases below.
What is a Realtime Database?
A real-time database refers to a database setup that relies on real-time processing for managing workloads with constantly changing states. It is different from a conventional database that is usually tasked with persistent data handling without being affected by time.
One real-world example of a real-time database is a stock market display that updates based on time-specific changes. It is seen in different global stock exchanges where real-time processing is necessary for making business decisions.
Real-time databases can be utilized for various use cases such as medical records, accounting, law, process control, data analysis, multimedia, and reservation systems.
Real-time databases are fundamentally conventional databases that rely on an extension for facilitating fast and instantaneous responses. These databases rely on time limits to the function, with data becoming valid for specified value ranges.
Unlike real-time databases, other conventional databases do not work with temporal validity as they deal with real-life elements rather than data on a system. Most real-time setups can handle time-specific queries, return valid data, and provide support for instantaneous scheduling.
In real-time databases, the physical system state is monitored by an input device, and the database gets updated with the latest information. Creating a robust real-time database requires developers to consider how valid time will be displayed in accordance with a real-time system.
Real-time database developers should also consider how values are to be represented for ensuring error-free transaction processing and consistency
Real-time database systems should also be capable of handling the eventualities of taking the right action when time deadlines are not met.
Going back to a real-life example, an air-traffic-control system performs instant monitoring of aircraft data and makes flight plan decisions. Real-time databases are also used for determining how planes should land based on data like speed, fuel and altitude.
Real-time database service providers offer a wide range of features and functionalities for the development needs of users. Currently, there are many database companies to consider for the average user. But, what are the key advantages of using real-time databases? Read on to discover.
Advantages of a Realtime Database
- Communications – A real-time database facilitates effortless real-time interactions between systems and users. Delay in communications is considered as a breakdown or malfunction.
- Collaborative experiences – A real-time database provides a setup that lets users work together on projects. In such use cases, changes after the stipulated time or the lack of change can waste time and result in duplication.
- Real-time user experiences (UX) – Real-time databases are integral for facilitating effective real-time user experiences. This is particularly applicable to scenarios where an action should result in getting feedback, such as mobile application button clicks, real-time chatting and more.
- Offline Synchronization – A real-time database also allows users to perform swift offline synchronization. This functionality is provided through features such as data saving on local disks. Any changes made when the server was offline get synchronized with a server’s current state when it is back online again.
- Splitting and scaling data – Real-time database lets users split available data and partition to different project databases. Database instances can also get established tiles.
- Multiple device access – Users of a real-time database can gain access to application data from different interfaces and devices across web and mobile platforms. It is one of the most important benefits of opting for a real-time database.
- Affordable options – Business owners and developers have access to various free and affordable real-time database options. Developers can easily opt for one of the many flexible pricing plans, where they pay for the downloaded or stored data amounts and number of connections.
