Syntax
Alphora, the creators of D4, have given it a Pascal like syntax. Sample code in D4 made by Alphora is usually written in UpperCamelCase, which is also widely used in Pascal and Delphi systems.
Like most query languages, D4 has a Data Definition Language (DDL) and a Data Manipulation Language (DML). D4 also has an Imperative Language for procedural code.
