YOUR APPS DESERVE AN AWESOME DATABASE LAYER

LIGHTWEIGHT | PORTABLE | POWERFUL

cross-platform

works on iOS, Android, Windows UWP, Windows, Linux (Mono)

lightweight

the Iridium libraries are just 200 kB in size. There's no reason not to use it in your projects

easy to use

adding database support to your app just takes a few lines of code

linq powered

data can be queried using LINQ, translating expressions to native SQL for best performance

multi database

supports Sqlite, SQL Server, PostgreSql, MySql and in-memory databases

powerful

does everything you would expect from a ORM, including relations, transactions, lazy-loading

Either connect to an existing database schema or simply create tables on the fly based on your entity classes

                            db.CreateTable<Customer>();

var customer = new Customer { Name = "John Doe" };

db.Insert(customer);

Read objects from the database by primary key or any LINQ expression

                            // Read a new object:
var customer = dbContext.Read<Customer>(customerId);

// or
var customer = dbContext.Read<Customer>(c => c.Name = "John Doe");
                        

Use native LINQ queries across relations and let Iridium figure out all the SQL JOIN and WHERE expressions

                            var orders = from o in db.Orders 
             where o.OrderDate < DateTime.Today 
             select o

var orders = from o in db.Orders 
             where o.OrderItems.Any(item => item.ProductID == "A") 
             select o;
