LDT

LDT stands for "LDS Drawing Tool".

LDS stands for "Logical Data Structure" coined by Professor John Carlis.

Overview

A Logical Data Structure is a way of graphically representing data. The notation is useful for quickly documenting and understanding complex data structures. This tool is intended to be a graphical editor for LDS, replacing pencil and paper.

Goals

• allow LDS to be drawn and edited quickly in a digital format
• allow LDS to be edited collaboratively over the internet by many editors
• assist in teaching LDS notation to software engineering students using computer graphics
