por Do you already know what Core Data is? If you are part of the world of technological development, it is necessary that you know and learn to use platforms, systems and tools that allow you to improve your processes. A clear case of this is the system of Core Data, which works as an Apple-designed option as a graphing and persistence framework.
However, this definition and characterization of Core Data falls short of all the functionalities and properties that this resource provides; that’s why, In this article, we tell you everything you need to know about itincluding its most important utilities, components and features.
What is Core Data?
Core data refers to an Apple programming scheme offered in operating systems on Mac OS and iOS. This template for software offers different means and tools for completing exercises related to the life cycle of objects or degree of objects, in particular, the data storage.
In a simple way, it can be said that this platform allows the conservation of information from an application without internet. The data preservation functionality of
Core Data also extends to temporary caching.
Although data persistence can be achieved through writing and reading files or through serialization and deserialization, using this tool has the following benefits: first, A graph of objects is generated to visualize the data or the model and, secondly, the work becomes simple with basic computing. This allows efforts to be channeled towards the development of the application.
Through the use of CloudKit as a container, Core Data operates automatically to unify content from multiple devices into a single iCloud account. Likewise, it is important to note that, from the Core Data model editor, you can define the types and connections of the data and consequently produce the nature of the system components.
Advantages of Core Data
The use of Core Data for data preservation includes a number of positive aspects that are advantageous for its users. First of all, as a fundamental utility, Core data offers the possibility of grouping, segmenting and organizing stored information. In addition, it is possible to avoid writing SQL and achieve complex and precise requests based on the applicability of objects. Fetch Requests and Predicates.
Likewise, the use of Core Data represents the scope of memory footprint (reduced memory impact) thanks to the function of faulting. On the other hand, from the administration of instances of objects in work you obtain features such as persistence, tracking of individual changes to be able to undo them, either in a group or specifically, and task fulfillment that provides background data.
Lastly, Core Data It encompasses favorable functionality in the migration aspect. Thanks to this frameworkmechanisms can be used to build versions of your data schema and mobilize user data as the application evolves.
Core Data Components
Regarding the Core Data Stack components, it is worth noting that this option works as a system of operating parts, having as its main objective to regulate the operation of the application with respect to data preservation. Its constituent elements are: Persistent store coordinator (wrapper from our database), NSManagedObjectModel, NSManagedObjectContext and Persistent container.
