Salient Features

• Offers a clean and efficient approach for developing business applications, microservices, Web APIs, Web apps, and small apps.
• Easy to setup and use.
• Fluent configuration API.
• CQRS - Commands, Queries and Notifications.
• Domain-driven Design (DDD).
• Supports a wide range of databases, including RDBMS like Microsoft SQL Server, Oracle, PostgreSQL, and MySQL, and NoSQL databases such as MongoDB and RavenDB.
• Event Sourcing is well-supported through the use of native EventStoreDB as well as RDBMS options like SQL Server, PostgreSQL, MySQL, and NoSQL databases such as MongoDB.
• Read Model Store - Offers efficient storage of flat and optimized data, supporting RDBMS such as SQL Server, Oracle, PostgreSQL, and MySQL, as well as NoSQL options like Elasticsearch and MongoDB.
• Sagas and transactions are well-backed, offering reliable features. Sagas can be implemented by using either the choreography or orchestration approach.
• Seamlessly communicate across distributed systems using Azure Service Bus and RabbitMQ messaging capabilities.
