ObjectBox: Open-Source NoSQL Database
Open-source NoSQL database built for speed, simplicity and flexibility, designed specifically for mobile and IoT applications, enabling direct object access and real-time performance.
What is ObjectBox?
ObjectBox is an open-source NoSQL embedded database designed specifically for mobile and IoT applications that require speed, simplicity and flexibility. Unlike traditional SQL databases, ObjectBox is optimized for accessing objects directly without the overhead of ORM mapping or object relational impedance mismatch.
Here are some key capabilities and benefits of ObjectBox:
- Blazing fast access speeds - ObjectBox is highly optimized for embedded systems and edge devices. It provides real-time performance even for complex data models.
- Small memory footprint - The database runtime itself is very lightweight, with a core library less than 600KB. This makes it ideal for mobile and IoT environments with memory constraints.
- Codeless object model - Define plain old Java/Kotlin/C++ objects and ObjectBox will handle the database modeling. This reduces boilerplate code.
- ACID transactions - Provides atomicity, consistency, isolation and durability for data integrity and handling multi-threaded access.
- SQL-like query language - Offers a fluent query API similar to SQL to find and filter objects flexibly.
- Cross-platform - Supports Android, iOS, Linux, macOS and Windows including x64, ARM32 and ARM64.
- Embedded or client-server mode - Can run standalone on the edge device or connect remotely to a central ObjectBox server.
Overall, ObjectBox aims to simplify mobile database development by combining speed, small resource utilization and flexibility within a consistent object-oriented programming model.
