Language Guide

This section details how to use the ALFA modelling language to express your data models.

ALFA syntax is designed to be concise and consistent. It is not opinionated on how your code is formatted. It has no restrictions on multi-line, sameline statements. Line/statement termination is not required ( E.g. no semicolon to mark end of a statement or declaration ). In some cases commas are required by way as a convention to separate items.

ALFA aims to be natural and easy to use with a very short learning curve. The Alfa compiler has been engineered to provide as much useful information in order for the modeller to be most productive as possible.

Those new to ALFA should first familiarize themselves with the Type System and modelling capabilities.
