The Best Database for Mobile Apps

A database is the storehouse of data consisting of multiple tables, rows, and columns. Different fields in the database are assigned with specific information. Businesses and dynamic websites often use a database management system (DBMS) to manage multiple databases.

A DBMS is a platform that helps developers integrate, organize, update, and control large databases. Statista’s topmost database management system in 2021 is Oracle, with a rank score of 1270.94.

In mobile app development, choosing the exact database is critical to handle frequent updates, complex queries, and store data offline. Mobile app developers are often astounded by the varied number of database choices in front of them. Therefore, this blog will work as a guide for you when it comes to picking the right database for developing or updating a mobile app.

The need for databases

A database can store enormous amounts of data that can aid in easy data retrieval whenever needed. Besides helping to access information, modern relational databases can let users update information in the database based on several pieces of information stored in different tables. A relational database is also capable of executing queries from multiple databases.

Here is the significance of a database:

1. A database protects the stored data via user logins and multiple other ways.

2. Database update is made possible via various Data Manipulation Languages.

3. A database stores data accurately via various in-built checks and restrictions.

Tips for choosing the right database for mobile apps:

So, the above points provided an in-depth look at the twelve best databases for mobile app development. Now, if you are wondering how to choose the correct database from the plethora of options available, here are some guidelines regarding the same.

1. Data Structure

Data structure refers to how you want to store and retrieve your data. This is essential because mobile apps store data in different forms. Online apps need to access a server to retrieve data, whereas offline apps need to access the smartphone’s local storage to store data.

On the other hand, synchronized apps store data on smartphones, but the stored data is updated on the server whenever the device connects to the internet. Thus, these apps can be used online as well as offline.

2. Data Size

The size of data points to the actual quantity of information that would be stored and retrieved by the app. When selecting a database, it is crucial that you select a database that can support the amount of data your mobile application would be dealing with at the peak of its usage.

The quantity and size of data can vary as per the data structure chosen. It is also influenced by how the database differentiates data across multiple servers and file systems.

3. Speed & Scale

If you need speed and scalability, then you need to go for databases that can handle the I/O needs of the app. Scaling is essential to address the time required to handle incoming read and write functions to your mobile application.

While some databases can handle read-heavy apps, others can support write-heavy solutions. On the other hand, other databases handle massive amounts of unstructured data, while others can better tackle structured data.

4. Data Security

Databases are often prone to hacking and malware attacks. They need to be protected with address authentication, data at rest and in motion, and read/write access to keep them secure. This is the case, especially when dealing with synchronized and decentralized storage.

For data at rest on the server and client-side, it is essential to have encryption for the level of both file systems as well as at data. For data in motion, it is required to have communication via a secure channel like SSL or TLS. For data read/write access, the database should be capable of offering granular control over the data. Sometimes many apps also need support for anonymous access.

5. Data Modeling

Data modeling plays a vital role if your app needs to have features like search queries, reporting, location support. These apps often need to interact with multiple databases for accessing different types of data. Performing data modeling can help understand the data structures which would be stored in the database.

6. Cross-platform support

Whether you want to build a mobile app for iOS or Android, you need to choose the mobile app platform too accordingly. If cross-platform support is a desirable feature for your app, then going with the React Native framework is the best option.

In Conclusion

You can select any database from the above-given twelve best databases for Android Or iOS mobile app development as per your requirement. If the app needs constant reads and writes, then CouchDB would be ideal for you, or if you are going to be dealing with a lot of unstructured data, then MongoDB can come in as the best database. So, you can refer to the latter part of the article to help you decide on the choice of database.
