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.

Example code

//Nuget: Install-Package OrigoDb.Core
//Restore graph by replaying commands stored on disk
//in the current working directory
var engine = Engine.For<MyModel>();

//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<MyModel>();

//void methods are translated to commands
db.MyCommand(someValue);

//non-void methods are translated to queries
var results = db.MyQuery(someValue);
