ObjectBox는 Flutter용 고성능 NoSQL 데이터베이스로 초고속이고 ACID 준수 객체 지속성을 가능하게 합니다. 봐일러플레이트 코드나 복잡한 매핑 없이 Dart 객체를 직접 저장할 수 있습니다. 속도와 간편함을 위해 설계된 ObjectBox는 Android, iOS, macOS, Windows, Linux에서 실시간 데이터 동기화를 지원합니다. 직관적인 API를 통해 개발자는 네이티브 객체처럼 데이터를 다룰 수 있어, 최소한의 오버헤드로 빠른 로컬 스토리지를 필요로 하는 앱에 이상적입니다. ObjectBox는 인덱싱, 쿼리 및 트랜잭션을 효율적으로 처리하여 신뢰성 있고 반응성이 뛰어난 성능을 보장합니다.
Flutter database with vector support - easy to use & fast Dart object persistence, plus on-device vector search 💙
Very first on-device vector database for Flutter / Dart AI apps. Intuitive APIs, simply fast.
Persist local Dart objects with ease & speed, efficiently manage vectors.
ObjectBox provides a store with boxes to put objects into:
// Annotate a Dart class to create a Box@Entity()
classPerson{
@Id()
int id;
String firstName;
String lastName;
Person({this.id = 0, requiredthis.firstName, requiredthis.lastName});
}
finalStore store = awaitopenStore(directory: 'person-db');
final box = store.box<Person>();
var person = Person(firstName: 'Joe', lastName: 'Green');
final id = box.put(person); // Create
person = box.get(id)!; // Read
person.lastName = 'Black';
box.put(person); // Update
box.remove(person.id); // Deletefinal query = box // Query
.query(Person_.firstName.equals('Joe') & Person_.lastName.startsWith('B'))
.build();
finalList<Person> people = query.find();
query.close();
ObjectBox Flutter database is an excellent choice for storing Dart objects in cross-platform
applications and the only on-device database that offers you vector support for your on-device AI apps.
Designed for high performance, the ObjectBox Flutter database is excellent for mobile
and IoT devices. ObjectBox consumes minimal CPU, memory, and battery, ensuring that your software is
not only efficient but also sustainable. By storing data locally on the device, ObjectBox allows you
to cut cloud costs and create an app that does not require a connection. Get started with our
intuitive native Dart API in minutes, without the hassle of SQL.
Plus: We built a data synchronization solution that allows you to keep data in sync across devices
and servers, both online and offline.
🏁 High performance - superfast response rates enabling real-time applications.
🪂 ACID compliant - Atomic, Consistent, Isolated, Durable.
💻 Multiplatform - Android, iOS, macOS, Linux, Windows, any POSIX-system.
🌱 Scalable - grows with your app, handling millions of objects with ease.
💚 Sustainable - frugal on CPU, Memory and battery / power use, reducing CO2 emissions.
🔗 Relations - object links / relationships are built-in.
💐 Queries - filter data as needed, even across relations.
🦮 Statically typed - compile time checks & optimizations.
📃 Schema migration - change your model with confidence.
Oh, and there is one more thing...
😮 Data Sync - keeps data in sync offline or online, between devices and servers.
Getting Started
Continue with our ➡️ Getting Started guide. It has resources and video tutorials on how to use ObjectBox in your Flutter or Dart app.
How does ObjectBox compare to other solutions?
ObjectBox is fast. Have a look at our benchmarks below, or test it for yourself
It's a full NoSQL SQLite alternative with intuitive Dart APIs you'll love 💙
It comes with an out-of-the-box Data Sync, making it an effective self-hosted Firebase alternative
Flutter Database Performance Benchmarks
We tested across the four main database operations, CRUD (create, read, update, delete).
Each test was run multiple times and executed manually.
Data preparation and evaluation were done outside the measured time.
Here are the benchmarks for ObjectBox vs sqflite vs Hive (last updated 2021-09-11) 👇
Do you want to check out the ObjectBox code itself? E.g. see it in action, run tests, or even contribute code?
