Best Databases For Mobile Apps 2024 – Choosing the Best One

It’s pretty challenging to pick the best when we have many options. The same happens with mobile app developers. They find it hard to choose the right database for an app. 

Here, the right database means the most suitable database that assists in building a mobile app and updating an existing one. The mobile app database determines if your app holds the caliber to handle multiple users (old or new) and regular maintenance and updates. 

This post will discuss the criteria for choosing the right database, top mobile app databases, and more. We ensure this blog will give you what you want when picking the right mobile app database. 

Let’s start!

What Is A Mobile App Database?

A mobile app database is an organized collection of well-structured information according to the app’s needs. 

The databases are housed electronically on a desktop or laptop and managed, edited, and updated utilizing database management systems (DBSM). The combination of the DBMS, the stored information, and the app all associatively makes a database system, or, we can say, a database. 

The data is stored in the database as rows and columns, making data management and processing fast and easy. 

What Is The Need For Mobile App Databases?

Besides an obvious requirement of a database, there are other needs of databases also. 

Read on!

The everyday use of a database is to store a large amount of data better. Let’s know about some more usages. 

Data Security

Mobile app databases ensure ultimate data security from hacking and theft. DBMS arrives with various user logins, and new users need permission to access the database every time. 

Pointing Out Errors

The information that app databases store is highly dependable as DBMS comes with a checking system that identifies errors that need removal.

Easy & Fast Search

Developers can quickly search through mobile app databases using Data Query Language (DQL). 

Hassle-Free Updates

DBMS includes Data Manipulation Languages (DML), which ensure timely and seamless updates of the app database. 

Types Of Mobile App Databases

You may find it surprising that mobile app databases are of different types. Let’s find out.

Distributed Database

When the data is stored across distinct physical locations in a database, it’s distributed. It can be located in various computers placed in the exact physical location or scattered over a network of interconnected computers. 

Centralized Database

A database where data is stored in a “center” spot is a centralized database. Here, the “center” location states the database is saved in a single place but can be accessed from any external resource. 

For instance, When you have complete data on your work PC, you will have easy access to it from your personal PC if that database is centralized. 

Cloud Database

Cloud-based database apps perform in the cloud. Such apps are a great innovation as they have a large amount of space to house data. The cloud is the technology over the internet that functions as a centralized database as it is always available, and one can access it from anywhere.

NoSQL Database

NoSQL is the only type of database that works uniquely from all other application databases. General mobile app databases store data in rows and columns patterns, but NoSQL arrives with a flexible schema that permits a developer to house data in various shapes and sizes.

Commercial Database

Organizations that run on enterprise-based database apps need an extensive database to house employee information.

Here arrive commercial app databases. These provide login controls and ample storage to ensure data security. 

End-User Database

When we enter our personal details on any social media page or online shopping site, that information is saved on the end-user database. Also, if you have seen the cookies we accept while browsing websites, the databases store cookies that help personalize your online experience. 

The whole process occurs in the background and doesn’t disturb user information. 

Relational Database

The growing firms always try to create relationships between two or more app databases. This is known as relational data, and a relational database eases handling such sort of data.

The data is stored in rows and columns in this app database, making it easy to build relationships between databases.

What is the general criteria to choose the right databases for mobile apps?

Various criteria assist in picking a suitable database for your mobile apps.

Read on!

Structure of Your Data

The structure points out the way you want to store and retrieve your data. Mobile apps deal with data in different formats. 

Offline applications store entire data on mobile devices, whereas Online applications rely on server access to let the store data function. 

Size of Your Data

The data size is the data quantity that you want to store and retrieve as crucial app data. The amount of data may vary according to a combination of chosen data structure, the caliber of database to differentiate data across various file systems and servers. 

So, you should pick a mobile database considering the entire volume of data generated by an app at any particular time and the data size you want to retrieve from the database. 

Data Modeling

Before selecting a mobile app database, you need to perform data modeling as suggested by experts. It’s a representation of data structures that you want to store in the database and robust expression of the business needs. 

Data modeling is best when your app holds features, such as reporting, search queries, location-based features, and more. Such mobile apps need various databases to handle distinct sorts of data. 

For instance, Uber uses various databases, like MongoDB, MySQL, etc. such databases help it store a high amount of incoming data. 

Speed & Scale

Scale and speed let us know the time incoming reads and writes to your app, demand to service. Some databases assist in optimizing read-heavy applications, while others are best to support write-heavy solutions. 

Choosing a database with the caliber to handle an app’s I/O requirements leads to a scalable architecture. 

For instance, MongoDB may be faster than MySQL to handle a large volume of unstructured data, but the latter is faster for structured data. 

Data Security

While using decentralized and synchronized storage, it’s essential to securely transmit, access, and store data. For this, you would address authentication, data in motion, data at rest, and read/write access. 

Authentication needs to be flexible and permit the use of public, standard, and custom authentication providers. For data at rest on the client and server, you need support for data-level encryption and file system encryption. Communication needs to carry over a secure channel for data in motion, such as TLS or SSL. 

Mobile App Platforms Choice

If you are planning to make apps for one or more platforms and thinking of deciding later, then you should consider them now. 

Today, various mobile apps are emerging to add a native desktop app or a web app. So, you should also think in this direction. 

If you want to develop mobile applications for Android and iOS platforms, you can use the React Native framework. It would be easier to build for both platforms simultaneously, as the developers hold the caliber to share code on both mobile app development platforms. Moreover, it supports all sorts of databases. 

Selection Criteria Based On Use Cases

Now, let’s check out the selection criteria as per the use cases:

Mobile Apps With Various Data Layers

Many apps that hold a multi-layer data model are tough to manage data as the “fields and tables” stay dependent on one another. 

Also, various apps change over time and demand alterations and modifications in the database structure. 

If you choose a structured database, like PostgreSQL, you will fail to make changes frequently. 

So, selecting an unstructured database, such as MongoDB, you would find it flexible to modify. 

Data Synchronization Between Backend Server And Local Database

Many apps come with features that allow them to perform offline but demand an internet connection to store local data to the application’s server. 

For instance, Dropbox facilitates editing and crafting new files even in offline mode. And when you go online, the changes get synced to the cloud.

So, choose the app database that can allow automatic local database sync to the cloud server and vice-versa, like Couchbase. 

For Highly Scalable Mobile Apps

While scaling your app, you think of appending more resources as servers that lead to an efficient database. 

The database needs to be multi-threaded according to which it should hold the caliber to use the resources and manage the parallel processing. 

Multithreading facilitates a database to schedule the parallel jobs on the current resources and reduce the workload on the server-side. 

Furthermore, you should also have a distributed database to split the services on varied threads to decrease the workload of the main database. This leads to improved parallel processing of databases. 

Resolve Data Conflicts Between Devices

A mobile app that changes the same data on various devices simultaneously may end up with conflicts. The database should always be supportive of conflict resolution mechanisms. It’s essential and should permit resolution automatically in the cloud, on the device, by a human, or an external system.

Users With A Low Network Issue

While transferring the required data, if the network connection of any SQL database disconnects from the client-side storage, it leads to an error message. And if it happens frequently, it may demand database re-configuration. 

So picking a database that provides better reliability and doesn’t lose connection frequently is better in this case. 

Pushing Database Changes & New App Updates

If we want to update our mobile app, it will demand some modifications to the local database. So, developers should stay updated with old database versions. 

The database you select should facilitate the addition of new tables and fields and handle old APIs and database structures for the users who have the latest app version. 

What Are the Best Practices for Working with Mobile App Databases?

Let’s now check out the best practices to consider for working with mobile app databases. 

Consider Databases that Follow the Multiversion Concurrency Control (MVCC) Method.

Such a method permits simultaneous access with no interference in processes or threads. 

MVCC facilitates a reader to check data snapshot before the writers make changes by permitting read and write operations parallelly. 

Predictive Caching

It is best to improve the mobile app’s performance by looking at when, how, and where users use your app. Based on their behavioral traits, you can identify the users’ segment and serve them with specific information they always want. 

You can cache and make data available locally before the users log in to your unique app ideas. You can also pick MongoDB as it offers predictive caching that permits developers to serve the users with predictive-cached data before they ask for it. 

Database Caching: To bring down the load

We should append a caching layer to decrease the servers’ load. Moreover, we need to cache data on this caching layer to avoid a recurring request for the same data. This lowers the number of requests approaching the server and makes the server’s performance more efficient. 

For example, mobile apps like Amazon receive various recurring requests. One can decrease the server’s load by appending the caching layer. It holds the caliber to manage millions of requests with the lowest latency. You can also use Memcached and Redic for such needs. 

Low Latency Challenges 

Low latency is vital for online gaming and real-time apps. High latency gives the app users the wrong impression. Anything that moves down from 500ms is a high latency. 

So, you can follow any method to reduce the replication and latency of the database. Moreover, you can choose databases with, on average lower latency:

• PostgreSQL – for transactional operations in real-time.
• Pipeline DB – SQL database best for streaming apps.
• RethinkDB –  best for real-time apps.
• MongoDB

Conclusion

Choosing a database is an important decision as it may lead to the making or breaking of your app. You need to check whether your chosen mobile app database fits the abovementioned criteria.
