Whether you are expanding the functionality of an existing application or developing a new mobile application, the proper database is critical.

Choosing the ideal database for your application may be a mind-boggling process, considering the variety of choices. Your existing database may be incapable of dealing with frequent changes and millions of users.

What exactly is a database?

A database is an organized collection of structured data that enables information to be accessible, easily updated, and managed. In simple words, a database is a location for data storage.

With its enormous collection of books spanning many genres, the library is the most incredible comparison. While the books serve as the data, in this case, the library serves as the database.

Why Are Databases Required?

The following arguments underscore the significance of databases.

Precise: A database is almost perfect since it has many checks, built-in restrictions, and more. This indicates that the data included in a database is primarily accurate.

Data Security: Database safeguard data via a variety of methods. User logins are required before accessing a database and its various access specifiers.

Convenient data updating: Using various DML (Data Manipulation Languages), changing a database is a breeze. One such example of the language is SQL.

Best Database for Mobile Apps

1. Cloud-based data storage

It is a Google and Firebase Platform scalable and adaptable database for server, browser, and mobile applications. It ensures data consistency among client applications through realtime listeners and offers offline support for mobile and web applications, allowing you to build responsive applications.

Features

• This is a critical element of the Firestore. When one of the transaction actions fails, the ACID or (atomicity, consistency, isolation, and durability) transaction ends the whole transaction.
• Designed for Native and Cloud Applications — It is optimized for native and cloud applications. As a result, it is an ideal option for retail catalogs, mobile applications, leaderboards, and social networking applications.

2. Postgres

Postgres is a free and open-source object-relational database management system that has been actively developed for over 30 years. It is renowned for its feature robustness, dependability, and performance.

Features

• Download for free: This open-source database may be readily downloaded from PostgreSQL’s official website.
• Compatibility with different programming languages: It supports JAVA, C/C++, Perl, Python, Tcl, and Ruby, as well as Open Database Connectivity (ODBC).
• PostgreSQL is compatible with all major operating systems, including Linux, Microsoft Windows, UNIX, and macOS X.

3. Back4app

It is one of the most outstanding open-source BaaS providers, helping developers rapidly develop scalable and flexible mobile and online applications. The fully-managed BaaS solution enables the provisioning and automatic scaling of Parse server-based applications.

Features

• SQL or NoSQL Databases: The service supports both relational and non-relational databases.
• Scalable Hosting: Many individuals are unaware of the degree of hosting services required when it comes to hosting applications. However, with Back4app’s scalable hosting solutions, developers have the freedom to scale their hosting services as needed to ensure that customers get the best possible performance.

4. MySQL

MySQL, a relational database management system, is used for various reasons, including e-commerce, data warehousing, and logging.

Features

• Convenient to use — If developers have a working knowledge of MySQL, they can build and interact with the database using simple SQL queries.
• Secure – It incorporates a robust data security layer that protects sensitive data safe from attackers. When developers connect to a server, MySQL encrypts their passwords.
• MySQL adheres to the server/client architecture’s operation. A database server is there, as are many random clients that interact with the server.

5. Couchbase

It is a distributed NoSQL cloud database that has won many awards. It provides unmatched performance, scalability, and financial value across on-premises, cloud, distributed cloud, hybrid, and edge computing deployments.

Features

• Constructed to meet extraordinary demand: On your cloud, you may run an elastic, distributed, and in-memory database. That is the architecture’s choice for NoSQL.
• Rapid development: Using various tools, SDKs, and tutorials, developers can quickly create applications on the stack and deploy them at the edge or in the cloud.
• The low total cost of ownership — Focus on capabilities with Kubernetes-based cloud-to-edge management. Scale securely, internationally, and affordably in your micro-data center, virtual private cloud, or edge device.

6. AWS DynamoDB

It is a document and key-value database that offers one-digit millisecond speed on any scale. It is a multi-region, fully managed, enduring, multi-master database with backup, built-in security, and internet-scale caching.

Features

• Scalable performance supports horizontal scaling tables, regardless of size. DynamoDB can grow to over 10 trillion requests every day with peaks of over 20 million requests per second.
• Enterprise Ready: created for mission-critical workloads, DynamoDB supports ACID transactions for a broad range of applications requiring complex business logic.
