Relational Databases

It is most extensively used type of database for mobile apps. The structure of the database comprises of coloumns and rows. It serves as an excellent platform for managing apps involving complex queries and data integrity.

Relational databases are suitable for apps that have well defined relationships and data schemes. PostgreSQL, Oracle DB, My SQL are some of the top relational databases for mobile apps.

Significance of Having Databases for Mobile Apps

Developing a database for mobile apps is essentialy as it impacts a series of functions running behind the app. These allow an app to store data, search information, interact with external databases, and gives protection against cyber threats. Below are some of the notable factor essential for seamless functioning of a mobile app.

Protection against cyber threats

Mobile app databases are necessary storage and safety of sensitive information. As a result databases always feature latest security functions like encryption and control mechanisms. These prevent attempts of data theft by unauthorized users. Besides database security is a critical element for keeping data safe whether in storage or in transmission.

Detection of errors

Mobile app databases ensure appropriate detection of errors. Inconsistencies like low quality data, outdated data, errors, etc. It is also helpful in cleaning up the database and removal of unwanted information. Such practices are essential for enhancing the response time and performance of an application. Besides it gives the end user peace of mind that the information is reliable and accurate.

Implementing a centralized structure ensure clear organization of database. It allows the mobile app to easily read and write data thereby enhancing the overall user experience.

Finding the right database for mobile application

Understanding the structure of data

Structure of data focuses on how one can store and retrieve information through a mobile app. Mobile applications primarily require handling of different formats of data. Offline apps can store all forms data, on the other hand online apps require access to a database for accessing information.

Synchronized apps are designed for storing data on the device for offline access. However the end user has access to server when the device is online.

Volume of data

Data volume describes the quantity of information that requires storage and access for app usage. It can vary based on the type of data structure and its ability of categorizing data across servers and file systems. Hence one should pick databases considering the volume of data available to an application at a particular time. Also the of size of data during retrieval should be taken into account.

Data model

Before shortlisting any database it is always best to perform a clear Data Modeling. It refers to the representation of data structure for storing in a database . Besides it is also helpful in making powerful expression for business requirements.

Data Modeling is specifically beneficial for apps that feature location based functions, reporting, queries, etc. Such type of features require access to various databases for seamless performance.

Performance

Performance is how fast apps can perform reading and writing of data. Some mobile databases offer optimization for heavy apps whereas others provide support for writing heavy solutions. Finding a database that can easily handle app I/O is vital for scaling the app in the long run

Performance is the efficiency of a database when working with data sets. An efficient mobile database ensures that the apps run seamlessly and gives quick response to the end user. A good quality database has lower response times making way for better data retrieval, storage, and updates. Slow response can easily turn down the users.

With time apps grow and evolve engaging more users. Hence the database should have adequate scalability to keep up with the changing demands. Developer must consider databases that integrate seamlessly with caching tools.

Just as performance speed also has a significant impact over the effectiveness of an app. People prefer faster application as they are more engaging to use. Quicker loading times have a higher user retention rates. Besides apps that come with realtime functions such as live update or chat require data synchronization.

Databases that allow seamless synchronization of data are easier to use when connected over internet. For financial apps quick updates and transactions is an absolute must. At the time of selecting a mobile app database, developers always value speed and performance. These are essential parameters for efficient functioning of the app.

Security factors

Apps using decentralize storage and synchronized operations require secure transmission, access, and storage. To ensure complete integrity it is necessary to ensure authentication, read and write access, and safety.

Flexibility of authentication is an important factor and must give access to public, custom, and standard authentication. Besides, support for anonymous access is necessary for proper functioning of some applications. For data storage both client and server requires encryption at data and system file level. On the other for data transmission a secure communication channel like TLS or SSL is helpful. Data bases should have granular control for read write access for data retrieval and modification.

Complexity of Query

Query complexity is a citical consideration for selecting a right mobile database for an app. It involves all the intricacies of the database queries, or the difficulty of retrieving and requesting information from the database.

Simple and straightforward databases allow faster querying. Besides developers must select databases that are able to manage the queries more efficiently. Databases that support indexing are known for providing significant efficiency in terms of query execution. The language of the query is another important factor that one needs to consider at the time of scaling the platform.

The overall data structure also has an impact over complexity of query. For example NoSQL databases are more efficient in handling specific forms of data structures and types. Besides developers should always take into account available resources and support based of the database of choice.

Compatibility across mobile platforms

The compatible platform for mobile app database is a vital consideration. At present developers are focusing more on creating apps that can leverage IoT and other emerging technologies. It is best take these into account right at the beginning. Several mobile apps now have a web version or desktop app. Hence it is something that will have a substantial impact over the usability of the app.

Apps that are compatible with both Android and iOS are based on React Native framework. Creating an app that supports both platforms is less resource intensive. As the code is shareable along with the databases.

Scalability

The below section talks about how picking the right kind of mobile app makes an impact over scalabality

Horizontal Vs Vertical scalability

Scallability for mobile has two types horizontal and vertical:

Horizontal scalability

It involving addition of higher number of servers within an app structure based on its requirement. This approach makes the app more cost effective and sustainable at the same time.

Vertical scalability

It refers to the addition of more resources like RAM, storage, and CPU over an existing server. It is specifically suitable for applications that has limited scope of growth.

Load balancing

It is the distribution of incoming requests from user in an even manner. Sharing the load across multiple server offers appropriate utilization of the available resources.

Automatic Scaling

Modern databases feature automatic scaling function to adapt with changing loads. The best no manaual intervention is necessary for the changes. Auto scaling makes certain that apps are able to make appropriate utilization of resources.

Budget

Budget is always an important factor in the selection of mobile data base. Some of them are available as open source while other require licensing charges. Therefore one must take into budget alongside other costing factors when shortlisting a mobile database. Following are the factors to consider.

  • Expenses of scalability
  • Expense for recovery and backup
  • Licensing charges
  • Development expenses
  • Support and training charges
  • Cost of integration
  • Maintenance costs
  • Charges for data transfer and bandwidth
  • Expenses for hardware

Stringent tests and benchmarking is helpful for evaluation of a mobile database in terms of reliability, performance, and scalability.

Database selection based on use cases

Mobile app using multi layer information

Modern mobile apps make use of data models consisting of multiple layers. One layer includes fields and tables which relies on another containing fields and tables. In such type of application managing information seamlessly is quite a daunting task.

Typically the application evolve with time and require certain changes within the database structure. Implementation of structured database is not sufficient for frequent changes.

The utilization of unstructured databases like Realm or MongoDB offers a lot of flexibility for making alteration within the app structure. Platforms like MongoDB allow users to add new functions and features without modifying the entire layout of the database.

Synchronizing data between backend and local database

A lot of mobile application come with features that work offline and use internet connectivity for storing data on the server. One notable example is Dropbox where the user is able to make changes or create new files offline. When the device has an active internet connection the changes sync with the cloud server.

Data synchronization has always been a significant aspect of creating mobile apps. One needs to be aware of the requirements and implement features accordingly. Selecting a local database that offers automatic sync service is necessary for storing information in the local database to cloud server.

Realm and Couchbase are quite popular among developers as it offers excellent synchronization between backend servers and the local database.

Dealing with users having network issues

In the event of an SQL server losing network connection from client storge, it shows an error message. As a result there is an interruption in the data transfer. If such errors take place often one should consider reconfiguring the database. Besides there are other challenges in terms of dealing with MySQL and other network interruptions.

Integration of new updates in the code and database

Implementing new updates in a mobile app needs a series of changes to the corresponding database. Hence the developers must keep in touch with the old database. The below section talks about how diffcult and crucial this step is for developers.

Let us consider an app running version 1.0 and has received an update for verion 3.0. The users are likely to start updating to version 3.0 skipping version 2.0.

The local database present here can manage such changes effortlessly. The database should easily include new fields and tables. Such apps require working around the database structure and old APIs for users making use of the latest structure.

Highly scalable mobile applications

Developers typically add more resources and make the database more efficient to scale an application. In such cases the database requires utilizing resources and handling parallel processes. A multi threaded database is more helpful for such purposes.

This technique is suitable for scheduling tasks simultaneously based on available resources. Besides it cuts down on the resources necessary on the server side. Another effective approach is Distributed Design which is equally important for scaling an application.

Eliminating data related confusions

Mobile apps that change the information across devices are likely to create conflicts in the process. The database makes use of a supporting mechanism for hassle-free resolutions.

Top Mobile app databases

Following are some of the well known mobile app databases for iOS and Android. Developers pick the databases based on speicific needs of an application.
