ER Diagram generator based on text

markER

Motivation

Drawing Entity Relation diagrams is a very time taking and tedious task which usually hampers industrial companies who are designing their databases for the first time. We propose a product that can automatically draw ER diagrams based on the user’s specifications, hence eliminating the need for manually drawing the diagrams.

Build Status

The project consists of the following components:

• Frontend explaining the interface of the project which has a window for typing the code and an output window displaying the ER diagram.
• Backend component parsing the code lines using a lexical parser and converting each parsed element into a token.

Code Style

Code has to be written in go language in the coding window.
