1. Consider memory handling capacity

In order to run an app without crashing, you need efficient memory handling. Even though most databases have automatic cache and memory-clearing mechanisms, you should always consider how well a database handles memory so that an app can work efficiently.

2. Complex data management

During app development, data is stored in various complex formats. It can be stored as key values or as a JSON structure. This is why it is absolutely necessary to choose a database that handles complex data structures with ease.

Adding more cooperation-associated features within the app generally creates more conflicts. You need to choose a database that clearly states the conflict management rules on its information pages. Keeping a check on such things in advance can save you a lot of trouble in the future while you are creating an app.

4. Data sync abilities

Currently, there is a rising need among users to use their apps in offline mode in some capacity. This can be due to any reason, like limited internet connectivity. This is why it is essential to use the database which offers the facility to synchronize data when users have re-established the connection with the internet.
