## Important notice!

OrigoDB is no longer under active development. Please check out [Memstate](https://github.com/devrexlabs/memstate) which is a complete rewrite of OrigoDB featuring major improvements in the areas performance, availability, licensing, cross-platform, docker and cloud support. Memstate targets .NET Standard 2.0 so will run on .NET Framework >= 4.6.1, .NET Core >= 2.0, Xamarin and Mono.

## In-memory database for NET/Mono

An Origo database is a command-sourced in-memory object graph.

Write your custom data model, commands and queries using any .NET language, or choose from a number of existing generic models.

OrigoDB is developed and maintained by Devrex Labs. We offer commercial support, consulting, training and enterprise features.

To learn more, visit the [project web site](http://origodb.com) and read the [online documentation](http://origodb.com/docs).

[![Build status](https://ci.appveyor.com/api/projects/status/v96t7i3a1kf0gqq3/branch/dev?svg=true)](https://ci.appveyor.com/project/rofr/origodb/branch/dev)

## Example code

```csharp

//Nuget: Install-Package OrigoDb.Core

//Restore graph by replaying commands stored on disk

//in the current working directory

var engine = Engine.For();

//Log a command to disk and then apply to in-memory graph

engine.Execute(new MyCommand{MyArg = someValue});

//read the in-memory graph using a custom query

var results = engine.Execute(new MyQuery{MyArg = someValue});

// -----------------------------------------

// Example #2 - Implicit operations

// -----------------------------------------

//restore graph and wrap the engine in a proxy

MyModel db = Db.For();

//void methods are translated to commands

db.MyCommand(someValue);

//non-void methods are translated to queries

var results = db.MyQuery(someValue);

```
