React Native application development relies heavily on local databases to store and manage data. Choosing the right database can make a huge difference in the performance and functionality of your application. The best local database for React Native applications is one that offers features like fast performance, offline support, seamless synchronization, and easy integration with other tools. With the right local database, developers can build robust, reliable, and scalable React Native applications that meet the needs of their users.

1. The Best Local Database for React
Native Application Development
Want to have the best Database for developing an app for your organization through a React
native app development company?
Here are some of the best local databases for react native app development which you can use for
your application development. Such as:
• Realm
Realm is licensed under Apache License. It is fast and easy to use and can handle large loads of
complex data.
React Native’s popularity lies in its ability to handle high-security securities and it has a variety
of encryption protocols.
Realm allows developers to:
• View, modify, and open the synced system
• And, instances of administrate realm object servers

2. Features:
• Realm is built in C++ and has excellent concurrency controls.
• Also, realm database can handle large data loads, and performance is assured.
• The database includes a query engine that allows you to search for and filter objects.
• It will enable you to create responsive mobile apps in any location.
• Besides, it provides object-oriented data modelling.
• Realm offers storage architecture using B+ trees to organize items.
• It allows synchronization via the log component feature.
• It provides robust security as the data is encrypted and remains there.
Advantages:
• User interaction is saved by constant background synchronization
• Realm has a great set of APIs.
• There are many encryption methods available for each mobile platform.
• Redux offline makes Realm offline-friendly
• It is open-source and can be used online and offline.
• React Native allows data synchronization.
• It will enable developers to develop cross-platform mobile apps.
Disadvantages:
• RAM usage is higher as the APK file size increases
• Moreover, model classes are not subject to any restrictions.
Who uses Realms?
• Patreon
• N26
• Peek Stack
• SQLite
SQLite is a software language that utilizes a serverless, zero-configuration transactional engine
and t is C language. In addition, this library provides ample storage to support mobile apps and is
a great React Native database.
SQLite is gaining popularity and is highly desirable because it stores all data on devices and it
allows software developers to depart from the traditional client-server model and can follow all
SQL-based policies. Instead, the mobile apps can easily integrate this small, reliable, fast
database engine.
The best part of the SQLite database is its react-native-SQLite-storage plugin, which can be used
for Android and iOS platforms.

3. React Native databases write content directly to files, not the server. The content can also be
stored as plain text or encrypted using an SQLite extension called SEE (SQLite Encryption
Extension) or SQLiteCrypt, etc., for app security.
Features:
• This database needs no setup.
• It is an independent platform that’s entirely free of external interference.
• SQLite’s source code is also fully readable and accessible to programmers and developers.
• SQLite database is saved in one cross-platform disk file.
Advantages:
• The SQLite database is light and easy to use on various devices.
• It is notable for its portability to 32-bit and 64-bit OS. You can link multiple processes to the
application file and work without interruption.
• It is a simple database that you can use easily, making it an excellent choice for your React
Native local.
• SQLite is a TCL extension. The main test suite for SQLite is in TCL. Thanks to its TCL integration,
thus, SQLite is easy to use with various programming languages.
• This database comes pre-installed for iOS and Android.
• Moreover, this database does not require installation and simply downloading the SQLite
libraries will create an intelligent database.
• Instead, it is portable, reliable, and easily accessible and its accessibility via various third-party
tools makes the task even more difficult because content can be accessed and modified with
short SQL queries, it is cost-effective.
Disadvantages:
• A con is the database size limit of 2GB in most cases.
• Also, SQLite doesn’t support multi-client concurrency.
Who uses SQLite?
• Alibaba Travels
• Accenture
• NetSuite Inc
• Firebase
Google owns Firebase, and it supports a NoSQL database. Firebase can manage MVC-based
reactive native apps that need an extensive database. Firebase is the best choice if you want to
create an app that requires offline data updation and synchronization. It’s compatible with SOX
regulations, thus, making it ideal for banking and finance.

4. Benefits of firebase local development
Firebase makes it easier to combine different apps.
• Data synchronization across multiple platforms is possible.
• Also, it is simple to set up and provides excellent security.
• Users can access it offline.
• Brilliant documentation
• Rapid prototyping
Drawbacks from the firebase-database
• It only supports iOS Features.
• Instead, it doesn’t work in countries that don’t allow Google
• Moreover, Firebase can help with data migration
• Real-time synchronization issues
• Watermelon Database
The watermelon database is excellent for react native app development. Moreover, it can handle
data persistence on slower devices, a difficult task with lazy strategies. You can get assisted by
hiring a React Native app development company with a watermelon database.
Benefits of watermelon database in react native development
• You can easily plug data into components.
• This allows an offline-first system via engine synchronization
• It also renders UI immediately after modifications in the database.
• App development using SQLite foundation.
Drawbacks from the Watermelon database
• To sync data, you will need to create a backend.
Conclusion
If you want to develop an app for your business, get assistance from an on-demand app
development company and finally build an app that will enhance your business.
