This mobile app framework allows developers to undergo frequent mapping classes, tables, foreign keys, or fields. It is an object-oriented database that saves a lot of time by running tons of queries faster than SQL databases.

Benefits of Realm database for React Native

  • Realm sync: The sync services operate in the background to record and save all the user interactions and local service requests. No task is left unexecuted as the data is transferred back to the server as soon as it is online & connects with a network. This ensures no hindrance in user experience while using the software.
  • Offline-first architecture Redux offline: Redux offline, ensures that it meets every arbitrary requirement of offline-based architecture. 

How secure is the Realm Database for react native apps?

It uses different encryption standards for each mobile platform. For Android it uses the ES-256 level of encryption, for iOS it uses the Common Crypto library, and for Windows applications, it uses the Crypto library for encryption. Each of these libraries is used to generate 64-byte encryption keys. These keys consist of a 4KB data block encrypted with the AES-256 Cipher Block Chaining (CBC) method and then signed with SHA-2 HMAC.

App Performance with Realm

  • Object-based database:  The objects get directly reflected in the database, and the framework does not convert the objects while doing read or write operations.
  • Zero-copy: Realm calculates, and reads the necessary data from the memory-mapped region and returns the raw value of the data. 
  • Concurrency control: The Multiversion Concurrency Control (MVCC) model allows multiple transactions at the same point in time. A user can execute both read and write operations without any hindrance.

Realm Pricing

Realm is an open-source available in free and paid versions. There are also new editions to it in the form of Realm Studio which also has other development features for enterprises.

#3 SQLite for Native apps

SQLite is designed to meet the storage demands of mobile applications. As the name says “lite” is said to be a lightweight library that requires minimal setup. This database for react native applications is integrated directly with the app to access the database in no time. 

Benefits of SQLite database for Native Apps

  • Acid compliant: SQLite has a file-based architecture with tools that can handle the database and guarantee its validation despite errors & failures. Acid stands for Atomicity, Consistency, Isolation, and Durability. These are the core properties of SQLite which make it authentic, simple, and easy to use in a way.
  • Offline persistence: It has a specific plugin named react-native-SQLite-storage that manages the database within the app.

How secure is SQLite for react native apps?

SQLite Encryption Extension (SEE) supports data encryption. The database charges a one-time fee license required to use the extension. To perform read and write operations the extension is built with various algorithms that protect the data from outsiders.

There are certain other implementations in SQLite for data encryption.

  • wx SQLite: A C++ wrapper used to encrypt SQLite data
  • SQLCipher: An open-source extension that supports 256 bits AES encryption. It uses OpenSSL’s libcrypto API.
  • SQLiteCrypt: It requires custom implementation and supports API-based encryption.

App performance with SQLite

SQLite performs faster when it comes to resolving queries. To optimize the SQLite performance, one just has to access the disk less often. But, to make such functionality work, the developer must have an overall understanding of SQLite information processing. One must determine the process where SQLite is consuming more time.
