So, you download this brand new mobile app that’s supposed to boost your productivity. You are excited. Then it slows down, crashes, or worse-loses your data-as you start using it. How annoying.
This is no small problem; it’s usually brought about by poor database choices during development.
In fact, research shows that nearly 70% of application failures are related to back-end issues, which include poor database performance. That can be very disastrous and costly for a business. Why? Because 25% of users quit an app after just one bad experience.
So, here is the million-dollar question: How do developers ensure that their app’s database will be fast, reliable, scalable, and secure-all at the same time?
In this post, we are going to break down the world of mobile app databases. We’ll explain what to look for when choosing one. By the end, you’ll know how to pick the best database for your app. You’ll ensure it works well, grows with your users, and avoids failure.
Key Takeaway
After reading this blog post, you will understand that:
- A mobile app database forms the backbone of an application, where all crucial data is stored.
- There exist two major types: relational or SQL databases and non-relational or NoSQL databases.
- Selection of the proper database depends on the choice of how it will store the data, the amount of data being used, the security to be granted, and the chosen technology for the application.
- The popular databases include MySQL, PostgreSQL, MongoDB, Cassandra, and many others.
- Developers must understand their app’s needs and compare database options carefully.
What is a Mobile App Database?
Think of a pizza shop. You need to keep track of orders, delivery addresses, and ingredients. A database is like the shelves in your stockroom, organizing all the information so everything runs smoothly.
For example, Uber uses databases to manage driver locations and bookings in real time. Similarly, your app might use a database to save customer preferences, store sales data, or even work offline.
A mobile app database is simply a digital collection of data. It’s arranged in rows and columns, making it easy to store, update, and access information. This is managed by a system called a Database Management System (DBMS), which handles tasks like:
- Checking if users are allowed access
- Adding, removing, or updating data
Mobile app databases support many app features, including:
- Offline Access: Apps can still work without an internet connection.
- Item Tracking: Keep tabs on products or services.
- Login Info: Store user credentials securely.
- Sales Data: Save and analyze sales records.
Why is a Database Necessary for Mobile App Development?
Databases are the backbone of mobile apps. They store data, make searching fast, boost security, and help find errors. Without a good database, your app might not work well or meet users’ needs. Let’s break down why databases are so important for mobile app development.
Storing Data
Databases are great at keeping large amounts of data organized and easy to access. In 2024, the global database market hit $88 billion, and it’s expected to grow even more—by 19% yearly until 2028. This shows how important databases are for apps.
When your app has a good database, it can quickly read and update data. This improves how fast your app works. For example, well-organized data can make access times up to 30% faster.
Finding Information
Databases make searching for information fast and simple. They use something called indexing to organize data, so it’s easy to find. Users can get what they need almost instantly, which makes them happier.
Apps with great search features have up to 50% better user retention, according to market data. This is a big deal for Android and iOS apps, where user satisfaction is key.
Keeping Data Safe
Security is more important than ever. Databases protect sensitive information with encryption and access controls. Did you know that over 70% of mobile apps face security risks?
App developers are using stronger database security to protect users’ data. This matters because a single security breach could cost a company millions and hurt its reputation.
Catching Errors
Databases are also great at spotting mistakes. They can quickly find bad or mismatched data, stopping problems before they happen.
This kind of error detection can lower app development costs by up to 25%. That means your app team can build user-friendly apps that run smoothly without spending too much.
What are the main Types of Mobile App Databases?
Understanding the necessity of a database is crucial for successful mobile app development. Whether using no-code methods or advanced tools, a database enhances your app’s performance and security. Now, we are going into detail to explore and identify the main types of mobile app databases.
Mobile app databases are divided into two main categories:
- relational or sequential databases
- non-relational or non-sequential databases.
Organizations can use these mobile app database types individually or together, depending on how they are using the data.
Relational or Sequence Databases
A relational database is one that can store related data and provide users with access to it. A sequence database is another name for a relational database. The following mobile app databases are relational or use SQL:
- MySQL
- Oracle
- PostgreSQL
- SQL Server
- MariaDB
- IBM DB2
MySQL
MySQL is one of the most well-known mobile app databases used in web app development. It is especially suitable for e-commerce, data warehousing, and logging. The main advantages of MySQL are its stability, robustness, and its ability to grow. MySQL is written using C and C++, utilizes SQL, and is used by businesses like Facebook, Uber, and Netflix.
PostgreSQL
PostgreSQL is written using C and is used by companies that work with a large amount of data. Gaming apps, database automation tools, and domain registration services use this type of mobile app database.
PostgreSQL is a proprietary, non-free RDBMS; the source code is not freely available. This is an ACID transactional guarantee: if there was a successful transaction where data was changed, then the modification will be saved. Since the licenses that PostgreSQL offers have three types of licensing that are available according to the needs of the customer, namely Community, Standard, and Advanced.
SQL Server
SQL Server is a relational mobile app database developed by Microsoft, ranking among the best. It is highly featured, hence popular, with such features as analysis services, reporting services, and data transformation services. This kind of mobile app database finds its application in health, finance, and educational industries, among others.
MariaDB
MariaDB is another popular mobile app database management system. It is compatible with MySQL Protocol and Clients. In fact, the MySQL server can be replaced by MariaDB without making any code changes. It offers a data structure that can be spread across many computers and can store data in columns. It is more community-driven than MySQL.
IBM DB2
IBM DB2 is a mobile app database that supports relational models. This type of database supports object-relational and non-relational features, such as JSON and XML. It is also known that the latest version of this mobile app database is DB2 11.5.
Non-Relational or Non-sequence Databases
Non-relational mobile application databases, otherwise referred to as NoSQL databases, store data in a less organized way than that of relational mobile application databases. These databases are useful when one needs to store a great volume of information that is not specifically organized or if your data requirements are not well known. Some examples of non-relational mobile app databases include:
- MongoDB
- Redis
- Elasticsearch
- Cassandra
- Amazon DynamoDB
- HBase
MongoDB
MongoDB is a popular mobile app database used by developers of iOS and Android apps. It is a NoSQL database, meaning that it is non-relational and stores data in JSON-like documents. MongoDB is known for its flexibility and scalability. It is also faster than MySQL when handling large amounts of unstructured data.
Cassandra
Cassandra is a database created by Facebook. It is a NoSQL database that works on mobile apps. Developers like it because it can handle huge amounts of data without slowing down.
Written in Java, Cassandra has many uses for app developers. Big names like eBay, CERN, and Fidelity use it too. This shows how reliable it is for handling large projects.
What makes Cassandra stand out? It is open-source, so it is free for anyone to use. Plus, it’s designed to handle unorganized data with ease, which is what modern apps require.
Choosing the Right Database for Mobile Apps
The success of your app begins with the choice of a proper database. A good database keeps your application at good speed, safety, and at the same time, it’s pleasant for the users. A wrong decision may lead to slow speeds, security issues, and miserable users. So, let’s look at how you can make the best decision for your app.
Data Structure
A data structure is how your app organizes and handles information. It’s key to making sure your app runs smoothly. Some common types include stacks, arrays, queues, and graphs. The right choice depends on what your app does.
For example:
- A navigation app might use graphs to manage routes.
- A to-do list app might need arrays to store tasks.
Think about your app’s purpose. A well-planned structure makes your app work better and gives users a great experience.
Size of Data
How much data your app handles matters a lot. It impacts what kind of database you need. Some apps need to store and process huge amounts of data, while others don’t.
For example:
- Social Media Apps need a lot of space for photos and messages.
- Utility Apps like calculators need much less.
Other factors include:
- Technology: Cross-platform apps often store more data than native ones.
- Online or Offline: Online apps need storage for real-time data, while offline apps rely on local storage.
Knowing your app’s data needs keeps it running well and can save you money.
Data Modeling
Data modeling is how you organize and represent your app’s data. It’s especially important for apps with complex features, like search tools or location services.
