Simple.Data

A lightweight, dynamic data access component for .NET, written in C#.

What is it?

Prompted by the need for an easy-to-use database access component which prevents SQL injection attacks while not requiring lots of boilerplate ADO.NET code or a pre-generated ORM model. Inspired by Ruby's ActiveRecord and DataMapper gems.

Instead of

public User FindUserByEmail(string email)
{
    User user = null;
    using (var connection = new SqlConnection(ConfigurationManager.ConnectionStrings["Default"].ConnectionString))
    using (var command = new SqlCommand("select id, email, hashed_password, salt from users where email = @email", connection))
    {
        command.Parameters.Add("@email", SqlDbType.NVarChar, 50).Value = form.Email);
        connection.Open();
        using (var reader = command.ExecuteReader())
        {
            if (reader.Read())
            {
                user = new User {Id = reader.GetInt32(0), Email = reader.GetString(1), Password = reader.GetString(2), salt = reader.GetString(3)};
            }
        }
    }
    return user;
}

why not just write

public User FindUserByEmail(string email)
{
    return Database.Open().Users.FindAllByEmail(email).FirstOrDefault();
}

and take the rest of the morning off?

Simple.Data does this by using the dynamic features of .NET 4 to interpret method and property names at runtime and map them to your underlying data-store with a convention-based approach. For the code above, there is no pre-defined type with a Users property, and no FindByEmail method. Within Simple.Data, that single line of code is converted into all the ADO.NET boilerplate for you.

Multiple database and NoSQL store support

Because Simple.Data provides a sort of dynamic Domain Specific Language to represent queries, inserts, updates and deletes, it is able to support not only a wide range of RDBMS engines, but also non-SQL-based data stores such as MongoDB. It has an open and flexible model of Adapters and Providers which make it simple to write plug-ins to map to almost any back-end.

Currently, Simple.Data has adapters for:

  • ADO-based access to relational databases, with providers for:
    • SQL Server 2005 and later (including SQL Azure)
    • SQL Server Compact Edition 4.0
    • Oracle
    • MySQL 4.0 and later
    • SQLite
    • PostgreSQL
    • SQLAnywhere
    • Informix
  • MongoDB
  • OData

Work is in progress to support Azure Table Storage. I'm also ensuring that Simple.Data works on Mono by the 1.0 release.

If you'd like to create an adapter or provider and need some help to get started, drop in on the mailing list (see below).
