![]() This is typically especially relevant when the database is a relational database (SQL) and the programming language used is object-oriented. It is a layer that sits on top of a database and makes it easier to use. We’re bringing this up mainly, because we see it confused often. What is an ORM?Īn Object relational Mapper (ORM) is not a database. Because Dart is an ambiguous term, the term Flutter database seems to be more useful. Dart is object-oriented programming language in which developers code Flutter apps. Flutter is an open-source UI software development kit created by Google. What is a Flutter / Dart Database?Īvailable platform-support for relational databases or native language APIs (bindings) for NoSQL databases may be very relevant to you, but does not determine the databases type. For this article, the most important differentiations are non-relational (NoSQL) versus relational databases (SQL), cloud databases versus edge databases. The most typical database operations are CRUD: Create, Read, Update, Delete. These types of operations are done within an application, in the background, hidden from end users. A database enables developers to store, access, manipulate, or delete data in the database via a developer language or API. As opposed to caching, data is reliably stored (persisted) and available to work with unless actively deleted. However, it is very likely it will perform similarly as sqflite, reflecting primarily the performance of SQLite.A database is a piece of software to store and systematically use digital information (data), in other words: data persistence. Moor was not part of the benchmarking as it is an ORM. It still may be a great option for you, depending on the use case. But of course cloud-based solutions have their own advantages and there may be reasons why you would choose to use Firebase over an edge database. Local data persistence, an edge database, will typically always beat a cloud-based solutions with regards to response times. If the objects are fetched using the async API from disk, the numbers drop by factor 1000.Īs a cloud-based online database, Firebase is not really comparable. However, strictly speaking it’s not a fair comparison, because in Hive, the high read numbers result from Dart objects already cached in memory. Hive can be faster at reading objects than ObjectBox. With regards to comparing Hive and ObjectBox, the results vary more. The results show ObjectBox performing with up to 70 times the speedup for create and update operations. Hive and ObjectBox clearly outperform sqflite across all CRUD operations. Summary of the Flutter Dart DB Benchmarks As noted above, Dart is an object-oriuented programming language. the data types they support, or the way they scale – and definitions can vary. However, databases can be further distinguished by additional criteria e.g. For our purpose, the most important differentiations are non-relational (NoSQL) versus relational databases (SQL), cloud databases versus edge databases, and maybe embedded versus in-memory. Many applications need a database as part of their technology stack. These types of operations are done within an application, in the background, typically hidden from end users. ![]() ![]() A database typically allows developers to store, access, search, update, query, and otherwise manipulate data in the database via a developer language or API. As opposed to mere caching, data is reliably stored and available to work with unless actively deleted. A database is a piece of software that allows the storage and systematic use of digital information, in other words: data persistence.
