Cell is a very high-level embeddable language. Cell's data model combines a staple of functional programming, algebraic data types, with relations and other ideas from relational databases.

Example from the web:
type AddUser = add_user( id: UserId, username: String, signup_date: Date, first_name: String, last_name: String, date_of_birth: Date? ); OnlineForum.AddUser { id =; // Inserting the new user id and setting all the mandatory attributes insert user(id), username(id, self.username), first_name(id, self.first_name), last_name(id, self.last_name), signup_date(id, self.signup_date); // Setting the date_of_birth attribute, if available insert date_of_birth(id, self.date_of_birth) if self.date_of_birth?; }
Example from the web:
reactive Thermostat { input: temperature: Float; output: on: Bool; state: // When the system is initialized, on is true if // and only if the current temperature exceeds 28°C on: Bool = temperature > 28.0; rules: // Switching on the air conditioner when // the temperature exceeds 28°C on = true when temperature > 28.0; // Switching it off when it falls below 24°C on = false when temperature < 24.0; }
