Type of Data 

You first need to understand the type of data that you will be storing and using. The structure of the data is also worth mentioning. The various kinds of data that you will be dealing with on a regular basis are relational data, documents, graphs, or a combination of all of these. If you can identify the kind of data, you can also ascertain the database model which is just right for your needs. 


The scalability factor is also worth your consideration. In the beginning, it is important for you to project how many users will be using your app. Can the existing database support that number? There are a few databases that can be scaled horizontally and a few that can be scaled vertically. You need to find out what your requirements and goals are, to get the best database model. 

Development Time and Cost

 If using a particular database, you have to take into consideration the development cost and time. It should also have the requisite development tools, so that you can work with them in future, too. If not, you must find out what additional software or hardware you need in the coming times, as the number of app users increases. You ought to choose a database that aligns with your goals. 


The security of your app data is of prime importance. Apart from that, you also need to make sure that the user’s data is safe. Your chosen database should be able to provide strong security features. It should come with encryption, access control, and authentication features. You might also want to check for compliance as per industry norms. 

Team Expertise 

You may also have to check if your current team has the expertise to handle the database that you are choosing. If you do not have the flexibility to learn and relearn, then stick to the knowledge base present. If you are ready for some extra investment in terms of hiring or training, you can experiment with other databases. 


 You also need to check how nicely the database integrates with the other tools, that you will be using. Compatibility will lessen the development time and maintenance time as well. You must also check for strong community support.

Selection Based On Use Cases 

Data synchronization between the local database and backend server 

Many mobile apps work offline and need the internet to save local data. Take the example of Dropbox, where you can edit and create new files, even when offline. When you connect to the internet, syncing takes place. Choose a database, which provides sync services. Couch base, which is NoSQL, can help in such cases. 

Mobile apps with multiple layers 

Multi-layer models in apps have fields dependent on others. It can be difficult to manage data in such types of apps. If you use something unstructured like MongoDB, it will bring in flexibility. 

Users having low network issues 

 When SQL databases encounter network issues, they send error messages instead of transferring the data. You may have to re-configure it later. Choosing a database that can resist connection loss is better. 

For highly scalable mobile apps

Your database should be able to handle additional load, with the expansion of users. Multithreading is a feature that comes useful. It allows the scheduling of multiple tasks. Distributed databases are better in such cases. 

Addition of new databases 

When you need to send notifications for new databases, some changes are needed on the local server. You should be able to add new fields to the local databases. Choosing SQLite as it can work fine, in such cases. 

Databases should be able to nullify conflicts 

When modifying the same data on multiple devices, conflicts may arise. So, the database needs to have the ability to resolve such conflicts. Flexibility with respect to conflict resolution is very important. 

Best Practices for Implementation

Choosing Database With Multiversion Concurrency Control 

This feature of the database allows simultaneous access, without blocking any threads or other processes. MVCC allows the reader to change the data, while simultaneously writing the changes. 

Predictive Caching 

It can be utilized to improve the performance of the app. The feature should allow suggestions to the app users, based on their behavior. The feature can allow the data to be cached locally, without the users logging in. MongoDB is quite proficient in this. 

Presence Of Low Latency 

This is another feature of the backend database, which is desirable. It is crucial for real-time apps and games. Replication of the database is one of the numerous ways a backend can reduce latency. Some databases with low latency are MongoDB Realm and Amazon DynamoDB, to name a few. 

Caching Databases 

This is another practice, which reduces the load on the servers. A caching layer can handle numerous requests with low latency. This is a practice that Amazon uses. Redis is one database that suits the purpose. 


So, if you are looking for a backend database, then these are the things that you need to look into. Mobile apps keep on changing, according to the business environment. That is why it needs to be highly flexible. Determine the right database for your app, after learning about the attributes and syncing them with your app goals. This will yield the best results.
