Criteria to choose the right database for react native

There are several factors to consider when choosing a database for React Native. In this section, we will discuss some of the essential criteria to help you choose the right database for your React Native application.
1. Data Model
The data model is one of the critical factors to consider when choosing a database for your React Native application. It refers to the way data is stored and managed in the database. There are three types of data models:
- Relational data model: This data model is based on the concept of tables, where data is stored in rows and columns. The relationship between the tables is defined using primary and foreign keys. Relational databases like MySQL, PostgreSQL, and Oracle are suitable for applications that deal with structured data.
- Document data model: This data model is based on the concept of documents, where data is stored in key-value pairs or JSON format. The relationship between the documents is defined using references. Document databases like MongoDB, Couchbase, and RavenDB are suitable for applications that deal with unstructured data.
- Key-value data model: This data model is based on the concept of key-value pairs, where data is stored as a value associated with a unique key. Key-value databases like Redis, Cassandra, and Riak are suitable for applications that require fast read and write operations.
Depending on the type of data your React Native application deals with, you can choose the appropriate data model.
