# Project structure

The framework codebase is split into a number of submodules, making it possible to only use what is needed.

* **Core**
  * **Revo.Core** Implements framework’s core features like events or commands and defines basic structures and interfaces for things like the unit of work pattern, security permissions and other utilities.
  * **Revo.DataAccess** Lower-level data access layer that provides interfaces and other abstractions for working with databases, independent of domain concepts (aggregates, consistency boundaries, etc.).
  * **Revo.Domain** Defines most of the framework’s building blocks for an application domain model – i.e. aggregates, entities, sagas, etc.
  * **Revo.Infrastructure** Interfaces for working with application domain and related aspects of an applications – e.g. aggregate repositories, event stores, projections, jobs, asynchronous event queues, etc.
  * **Revo.Testing** Provides several useful facilities for easier application testing – e.g. assertions for event-sourced aggregates or fake repositories (refer to the [Testing](/reference-guide/testing.md) chapter).
* **Providers**
  * **Revo.AspNetCore** Provides support for ASP.NET Core applications – application life cycle hooks, user context, authentication, etc.
  * **Revo.AspNet** Provides support for ASP.NET applications – application life cycle hooks, user context, authentication, etc.
  * **Revo.EasyNetQ** EasyNetQ integration for event messaging via RabbitMQ.
  * **Revo.EFCore**

     Data access and infrastructure (aggregate store, event store, async events...) implementation using Entity Framework Core.
  * **Revo.EF6**

     Data access and infrastructure (aggregate store, event store, async events...) implementation using Entity Framework 6.
  * **Revo.Hangfire** Hangfire integration for background jobs.
  * **Revo.Raven** Data access layer implementation using RavenDB database system.
  * **Revo.Rebus** Rebus integration for command/query and event messaging with RabbitMQ.
* **Extensions**
  * **Revo.Extensions.History**

    Change-tracking and entity history features.
  * **Revo.Extensions.Notifications** An extensive and customizable framework for user notifications (including mail notifications, push notifications, etc.).
* **Tests**
* **Examples**

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.revoframework.net/general/overview/project-structure.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
