This is the most well known relational database across both iOS and Android. Let’s examine some of the most popular examples of databases and then look into Realm. Readability: The data is much easier to read, both in the database and when used in the application, because it shares the same shape. By using an object-oriented database, queries across those objects will be much faster.ģ. Performance: Sometimes, there will be complex object-to-object relationships between the data. Complex data can be stored as objects, avoiding any potential unintended consequences due to the conversion to a row in a relational database table.Ģ.

This means it’s a great solution for iOS apps written with Swift, because there won’t be a need to map the objects for data persistence.

Object-oriented databases were created to keep the data consistent between how it’s used in code and where it’s stored. This ORM takes additional time and code to implement, slowing down development time. If the data was being persisted into a relational database, an object relational mapper (ORM) would need to be used to convert these objects into the tabular, row-based storage of relational databases. Simplicity: Swift, like Objective-C, is an object-oriented programming language, which means that the data being persisted to a database will start out as objects in the application code. There are a few advantages to consider that make object-oriented the best database type for iOS apps:ġ. It takes care of the complexities of syncing data between two data sources with networking code, conflict resolution, and error handling, which improves developer productivity.Īdvantages of object-oriented databases for iOS This leads to fast, real-time, reactive mobile apps that save data in the cloud and locally. Cloud and local storage: One way to solve the issues of connectivity is to store data both locally and in the cloud using Device Sync. However, this still requires internet access so raises the same concerns around connectivity.Ĥ. For this reason, you will want to consider a database that supports this type of storage location and connection when persisting data for mobile. Server: You may prefer to host your data using your own servers or data center.

However, the driver used to communicate with Atlas requires network access at all times, meaning a less optimal user experience when offline or with a slow connection.ģ. For example, MongoDB Atlas, MongoDB’s multi-cloud application data platform, MongoDB’s multi-cloud application data platform, combines a flexible document model and unified query interface with automated horizontal and vertical scaling, flexibility, easier database sharing between project types (including mobile), and much more, to provide a first-class developer experience. A cloud database has several advantages over traditional storage. To overcome this, mobile developers will need to save the data from their apps to the cloud or a self-hosted server. However, this functionality is not supported by local-only storage solutions. Cloud: Data sharing across devices and a centralized back end is a common feature of iOS applications. With data stored locally, apps continue to be functional, even when offline, leading to a much better user experience.Ģ.

Internet connection can be inconsistent on mobile devices. Local storage: Having the data available offline by storing it locally is an important feature in mobile applications. The following factors, therefore, are worth considering:ġ.

Where a database is located, aka hosted, is an important factor with iOS databases. Code is often simpler as well due to closeness in structure between the database and object in code. It’s able to do fast queries with complex data. This can work with complex data objects as used in object-oriented programming languages, such as Swift. An example would be UserDefaults, available out of the box with the iOS SDK. It’s most commonly used in iOS to store small bits of information available at app launch. This uses a key (sometimes known as field) to value mapping, to store the information. This is the choice if the relationship between the data is heavily connected The most common example for iOS databases is SQLite using Core Data as a persistence framework. The tabular format uses keys to form relationships between the tables. There are multiple different database providers that are compatible with iOS but they broadly fall under three categories: relational database, key-value database, and object-oriented datrabase.
