ObjectBox vs Realm: What are the differences?

Introduction:

ObjectBox and Realm are both popular mobile database solutions for developers. While they have some similarities, there are key differences between the two.

Data Model Flexibility: ObjectBox offers a highly flexible data model, allowing developers to easily create and modify their data structures without needing to make any changes to existing data. Realm, on the other hand, enforces a stricter data model and requires developers to explicitly handle schema migrations when making changes to the data structure.
Performance: ObjectBox is optimized for performance, offering faster read and write operations compared to Realm. This is achieved through its unique architecture and indexing mechanism, which allows for efficient data retrieval. Realm, although still performant, may face some performance limitations when handling complex queries or large data sets.
Relationship Handling: ObjectBox provides built-in support for object relationships, including one-to-one, one-to-many, and many-to-many relationships. This makes it easier for developers to handle related data and perform advanced operations. In contrast, Realm does not have native support for relationships and requires developers to manually handle them by implementing additional logic.
Platform Support: ObjectBox supports a wide range of platforms including Android, iOS, and Linux, making it suitable for cross-platform development. On the other hand, Realm provides support for various platforms including Android, iOS, Xamarin, and React Native, offering a slightly wider range of options for developers.
Community Support and Adoption: Realm has been in the market for a longer time and has gained significant community support and adoption. This means that developers can find more resources, tutorials, and forums related to Realm, making it easier to find solutions to common problems. ObjectBox, being a relatively newer solution, may have a smaller community and fewer online resources.
Licensing Model: ObjectBox offers a more flexible licensing model, including a free Community Edition along with commercial options for larger projects. Realm also provides a free version, but its commercial licensing may be more suitable for enterprise-scale applications.

In Summary, ObjectBox and Realm have key differences in terms of data model flexibility, performance, relationship handling, platform support, community support, and licensing model.

Detailed Comparison

Realm	ObjectBox
The Realm Mobile Platform is a next-generation data layer for applications. Realm is reactive, concurrent, and lightweight, allowing you to work with live, native objects.	It is for developers who look for performance and ease of use. We are committed to providing you with the easiest APIs for you to keep your code short and maintainable. No SQL under the hood-Simply faster. Unlike other databases, it has been built from the ground up using key-value storage instead of column storage. The resulting performance is 10x faster than the leading alternative, we welcome you to try it yourself. It is fast regardless of the amount of data or operating system you are using.
Feels like Home - Realm’s data structures look like the Objects and Arrays of your language, but provide additional features such as: querying, relationships & graphs, thread safety, and more.;Memory-Efficient - Realm is not built on SQLite. Instead, a custom C++ core is used to provide memory-efficient access to your data by using Realm objects, which usually consume less RAM than native objects.;F-F-Fast! - Realm offers extraordinary performance compared to SQLite and other persistence solutions.	10x faster than any alternative; Reduces cloud costs up to 60%; Supports Linux, Windows, Mac/iOS, Android, Raspbian, etc. Embedded or Containerized; Develop applications that work on- and offline, independently from a constant Internet connection, providing an “always-on”-feeling; Accelerate time-to-market, save development and lifecycle costs, save precious developer time for tasks that bring value

What are some alternatives to Realm, ObjectBox?

MongoDB

MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.

MySQL

The MySQL software delivers a very fast, multi-threaded, multi-user, and robust SQL (Structured Query Language) database server. MySQL Server is intended for mission-critical, heavy-load production systems as well as for embedding into mass-deployed software.

PostgreSQL

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions.

Microsoft SQL Server

Microsoft® SQL Server is a database management and analysis system for e-commerce, line-of-business, and data warehousing solutions.

SQLite

SQLite is an embedded SQL database engine. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite reads and writes directly to ordinary disk files. A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file.

Cassandra

Partitioning means that Cassandra can distribute your data across multiple machines in an application-transparent matter. Cassandra will automatically repartition as machines are added and removed from the cluster. Row store means that like relational databases, Cassandra organizes data by rows and columns. The Cassandra Query Language (CQL) is a close relative of SQL.

Memcached

Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.

MariaDB

Started by core members of the original MySQL team, MariaDB actively works with outside developers to deliver the most featureful, stable, and sanely licensed open SQL server in the industry. MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.

RethinkDB

RethinkDB is built to store JSON documents, and scale to multiple machines with very little effort. It has a pleasant query language that supports really useful queries like table joins and group by, and is easy to setup and learn.

ArangoDB

A distributed free and open-source database with a flexible data model for documents, graphs, and key-values. Build high performance applications using a convenient SQL-like query language or JavaScript extensions.
