Many apps rely on databases operating behind the scenes to provide their key functionalities to users seamlessly and consistently.

With a number of different database options to consider, it is sensible to weigh up your options so you can work out which of the competing platforms is the best for your needs. To assist in this process, here are some of the key considerations to keep in mind as you are comparing databases ahead of forging ahead with app development.

Assess data storage needs

The first point on the agenda relates to how and where the data used by your app will be stored. If the app is to function entirely offline, key information will obviously need to be kept on the device in question so that it can be accessed whether or not a network connection is available.

On the other hand, if the app is entirely reliant on access to the internet, then the database will need to sit on a separate server infrastructure.

You may even work with a virtualized database, which can deliver a number of advantages including improved resilience and simplified testing, according to Kevin Kline. In this case an SQL-focused database, either powered by paid platforms like SQL Server or derivatives of open source equivalents such as MySQL, could fit the bill.

Analyze speed requirements & scalability

Database speed will clearly have a direct impact on app performance, yet there are different approaches to optimization available depending on the intended use case.

For instance, structured data can be handled more quickly by a platform like SQL Server, as well as affording developers far more scalability to encompass long term expansion. Meanwhile alternatives like MongoDB do better when non-relational needs are on the table.

Once again it is a case of deciding in advance what you want to achieve with the database and then applying these findings as part of the decision-making process, rather than going in blind.

Scrutinize security capabilities

You will want your app to be as secure and resilient to breach attempts as possible, and so you need to make sure that the databases on your wish list are all able to provide adequate levels of protection.

There are various security-focused features to look out for, including authentication, data encryption and secure transmission capabilities that will keep it safe when it is being sent from the server to the end user's device.

Consider compatibility

The final thing to note when seeking out a database for your next mobile app is the extent of its compatibility with the most popular mobile operating systems.

While it is safe to assume that mainstream solutions will work with iOS and Android, whether through native implementation or third party APIs, you should also think about where else you want your app to appear, whether that might be in a browser-based environment or on wearable tech.

Most importantly, take your time and carry out a thorough investigation of prospective database platforms before committing.
