Mobile app database stores all the user information and makes it accessible whenever needed. The database is the most standard way of storing and managing data. As new technologies are emerging in the form of big data, data science, the need for developing robust databases for a mobile app is increasing too.
If you are an app owner and in the middle of mobile app development process and looking for the right database solution for your mobile application you might be confused with the various database options.
Your app developer or software engineer might choose Oracle as the most popular database, followed by MySQL, Microsoft SQL Server, PostgreSQL, and MongoDB. But for mobile app development, you will need to choose the right database that fits best to your development requirement and future goals.
So if you are in search of which is the best database for your mobile app, this blog post will tell you the right information to help you choose the perfect database framework for your app project.
What is Database?
A database is the storehouse of structured information that enables information to be accessible, easily updated, and managed. The database can be also referred to as a location where all the essential data and reports are stored.
Here, the information stored is extremely sensitive which is why you need to be ultra-careful while accessing the information in the database of your mobile application.
Most Popular Databases for Mobile App Development:
- SQL Lite
- AWS DynamoDB
Types of Mobile App Databases
1. Data Warehouses
The data warehouse is a kind of data management system which is built to enable and support business intelligence-based activities such as analytics.
Data warehouses allow developers to consolidate and centralize large amounts of data. Its analytical capability helps app owners and businesses to derive valuable insights which can help them improve their decision-making processes.
Key Features of Data Warehouses:
- Subject oriented
2. Distributed Warehouses
This database stores information across geographically distant locations with no physically shared resources. A distributed data warehouse is an ideal choice for your mobile app if your users are spread across different geographies.
Key Features of Distributed Warehouses:
- Increased reliability and availability
- Easier expansion
- Fragmentation transparency
- Better performance
3. Operational Database
Operational database enables users to edit or remove data in real-time. Most database types depend on batch processing which means the edits are only made till a specific threshold in resources and time.
But operational database can make your data operations functional in real-time. Therefore, it is the best type of database if you want to store employee, customer, and payroll information.
Key Features of Operational Database:
- Dynamic in operation
- Highly secured
- Highly scalable
4. Relational Database
Relational database organizes data into tables linked or related to each other based on shared information. It enables the users to retrieve an entirely new table from data in one or more tables with a single query.
Relational database is the perfect choice for your best technology stack for mobile app development if you want to understand the connection among all available data better and gain new business insights for well-informed decisions.
Key Features of Relational Database:
- Ease backup and data recovery
- Reduced redundancy
How to Choose the Best Database for Your Mobile App?
Now that you have got a basic understanding of what is database and what purposes they serve, it's time to cover the most important points that you should keep in mind while selecting the database for your mobile application.
1. Data Structure and Mobile App Requirements
The data structure has a big role in managing how data should be stored and retrieved when needed. Different mobile applications are made on different mobile app development frameworks. Therefore, you need to choose the appropriate database to support the right data structures that can be used for storing and retrieving data.
2. Data Size and Storage Requirements
Data size is about the quantity of data you need to store and retrieve sensitive app information for your app to perform properly. Hence, you need to consider the data size how much your mobile app is capable to handle.
3. Data Security and Flexibility
Data security is today's hot concern and never compromising thing for both users and app owners. Storing your mobile app data on a database service provider can lead to various data threats and vulnerabilities if the database for mobile applications is not safe or has strong security features.
4. Mobile OS Platform Support
You need to make sure while choosing the database for your mobile app whether it supports native mobile OS, hybrid mobile OS, or cross-platform OS support.
As there are mainly two main popular mobile OS platforms- Android and iOS. Technology has transformed mobile devices and connected other emerging technologies like wearables and IoT devices. Therefore, it becomes essential to decide how many mobile OS your database support.
5. Resolving Data Conflicts between Devices
Any mobile app which modifies the same data on multiple devices simultaneously can create data conflicts. The mobile app database you select should support a dynamic mechanism for resolving these conflicts. Most mobile app databases come with the capability to automatically resolve such conflicts on the device, or by human intervention.
Which is the Best Database for Your Mobile App?
There are certain characteristics that differ for different databases. By identifying these properties you can sort out the available mobile app databases depending on your mobile app development requirement. Here is the list of the popular databases available in the market that you can choose for your mobile app.
