A developer must be aware of a plethora of back-end tools when using React Native databases. However, the database must be chosen based on requirements. Ergo, you must first understand your requirements before looking for an ideal database for your react native application.

Native Databases
For App
Development

databases for React
Native development

4. Realm Database
The Realm was launched in 2004 to ease
development and help developers with
mobile applications faster. It is a cross-
platform, open-source, object-oriented
database used in mobile and website
development.
Realm Database constitutes two components
Realm database and Realm object server.
These elements work together to
automatically synchronize data, allowing for
a wide range of use cases, from offline
applications to complex backend
integrations.

5. SQLite
Are you looking for a grounded and designed database for your
react-native app development? Well, the SQLite database is the
one. It is an RDMS (relational database management system) for
solving the mobile app's storage requirements.
The term SQLite where Lite described as lightweight, meaning
the database is lightweight and requires minimal setup,
database administration, and resources.
Furthermore, it allows you to write the content into different
files directly and does not require a server separately. The data
stored in the form of plain text format can be encrypted using
the SQLite Encryption Extension (SSE).

6. Firebase:
Firebase is owned by Google and supports a NoSQL
database. It can manage MVC-based react native apps that
require a high database. And if you want to develop an
app that requires offline updation of data and
synchronization, Firebase is the ideal choice.
Moreover, it has a tool that tracks performances to help
you detect the bugs in your app, and you have access to
remove the data anytime from the Google server. It is
highly compatible with SOX regulations which makes it
best for the finance and banking industry.

7. Watermelon
DB:
It is another react-native database like SQLite.
Watermelon DB can precisely scale million of records
without losing its speed within a minute. It is a
database that must be considered for react native
app development due to its ability to handle data
persistence on slower devices which is a daunting
task using lazy strategies.
According to Github, it is used to create demanding
apps that focus on real-world performance.

8. PouchDB:
PouchDB is an open-source and lightweight
javascript database that stores data in JSON
format and enables all read, delete, update
and create functions using JS API.
When using the app offline, it stores data
locally, and then later, after getting a proper
internet connection, the data is then
synchronized with servers and CouchDB.
It also offers replication features to sync data
with multiple clients without any data loss.
Moreover, it is best when it comes to data
security.

9. Vasern:
Vasern is known for its fast, open-
source, and lightweight features and
was developed using Golang s
server-side language by Google. Its
API is used to create local
data, cloud storage, and syncing
across the app’s clients. Vasern
design and structures got motivation
from various open-source databases.

10. BerkeleyDB:
Berkeley DB is a publically available, high-
performance React Native backend platform that
enables developers to manipulate data differently.
It has an API for different languages, including iOS
and Android.
It can handle data in various ways, including
relationally, as SQLite does, or byte arrays, and it
supports numerous data items for a single key.
