Mobile apps are the most important components of a smartphone, which is why every mobile app needs to possess both the best offline and online capabilities, as well as synchronization, which is the key to a successful mobile app. Mobile apps are widely used for different types of purposes, and thousands of apps are created every day. Each app has to perform to its fullest to get noticed and stay on top all the time.

No matter what purpose an app targets, if it doesn't work well and relate to the audience, it won't be used. Or it will be downloaded and then removed with no mercy. This is why syncing the right database for your mobile app is a quite substantial aspect of high-performance mobile apps. A suitable database makes sure your app stays reliable, responsive, and competitive under all circumstances.

What Exactly Is a Database?

A database is simply a software or a basic component that is used for developing mobile apps. There are a variety of databases that can be used to develop a mobile app depending on the purpose or requirement of developing the app.

In order for you to choose the right and suitable database for your mobile app, here are some tips you should consider before you ever begin building your app.

1) Dynamic and Flexible Data Model

A flexible data model is helpful for determining just how one can effectively and efficiently articulate the model requirements for their apps. A flexible data model with dynamic qualities also determines how efficiently a given model evolves to the changing requirements of a mobile app. Having an adaptive model is very important since mobile apps are always improving and evolving and getting updated from time to time.

If you have a flexible mobile database in place, it will be easier for improvements and new updates to take place. A perfect example of such a database is NoSQL.

2) Safety and Security of Data

After performance and speed, one of the most important qualities of a good app is security and safety when it is being used. It’s important for a mobile app to provide a safe system for accessing, storing, and transmitting data when a decentralized, as well as synchronized storage, is being used. It is also good to make sure it allows friendly data authentication for the targeted users of the mobile app.

3) A Tab Should Be Kept on the Data Structure

The structure of the data is the determining factor of how a data is stored or retrieved, and it’s very important to get the right database structure, as a database is made up of information and data in a variety of formats. This is why it is of great importance for the right data structure to be used as it plays a major role in the process of storing and retrieving of data.

If the wrong data structure is used, a mobile app will cost a lot of time and effort for development to take place and also to fix any issues that may be related to data. Using the right data structure is of paramount importance to the implementation of information or data.

4) Speed and Scalability

It is important to have a high speed reading data from the database as well as writing them to the database. Some mobile apps will be heavier than others, and they will require databases that are crafted to handle such apps without any issues.

There are also several databases that are used perfectly for handling and supporting heavy writing solutions. A database that can handle either the input or output of a mobile app can go a very long way in the building of scalable and effective android apps for users.

5) A Conflict Resolving Database

Some mobile platforms use decentralized data writes that can be used or modified on other devices, which thereby creates a conflict. An ideal database system needs to be capable of solving this conflict with a mechanism in which it supports. It is important for a database to have a flexible conflict resolution system which can allow conflict resolving automatically on aloud storage by either a human or an external system.

It’s important to know that conflict resolutions will be different for each system. For example, clock-based resolution systems are more problematic because of the issues that can be seen around the clock differences across devices. A Couchbase mobile utilizes revision trees with a default resolution approach of the most active brand winning.

This approach is also shared by a control revision system like Git, which greatly differs from a clock-based system approach. The Couchbase system allows customization through code from the user or a code on the server in order to carry out more effective conflict resolution.

6) Perfect Synchronization at the Right Moments

A good database should be able to determine how the system synchronizes, and this could be through a replication strategy, which involves filtering and conditional replication. A replication strategy takes support for activities like polling, pushing, and streaming, and with a good database, these strategies can be combined.

For replications where filtering is used, some data should be able to be replicated but not all of it. And lastly, conditional replications may need to be replicated only in certain circumstances, like when the device has enough power or when the device is connected to the WiFi.

7) Synchronization Should Follow the Right Partition

In order to meet partition requirements, a configurable synchronized topology will be needed. This means that the system needs to be configured so certain parts can be operable offline. One of the most commonly used topologies is the star topology where every device is connected to a central hub with a point-to-point connection used, which allows being able to carry out offline operations.

The tree and mesh topology are also commonly used, and they allow a variety of system parts to function offline, including the devices. An example of a tree topology system is the POS (point of sale) system. It requires the continuous operations of a brick and mortar store if it is ever disconnected from the rest of the system.

Such a configuration involves POS devices synchronizing with store level databases, which then synchronizes with the worldwide system. With this activity, stores would still be able to continue to carry out the other operation and synchronize data with POS devices even without being connected to any global system.

Getting support from cloudless topologies may also be a need because it is cloudless topologies that facilitates devices to communicate peer to peer and enabling them to synchronize data amongst themselves directly is often the primary necessity.


The choice of selecting a suitable database for your mobile app is about making sure you have the optimal database in place. It is good to consider all the above factors as you look for mobile synchronization and storage providers for your mobile app.

If you intend to build a flexible, manageable, and secure mobile app that delivers competitive performance in both online and offline modes, these are three vital areas of considerations for choosing a database:

  • The mode of synchronizing your app

  • The size of your app

  • Whether the mobile app belongs to cross-platform app development
