Colorize specific attributes

Introduction

Using the data modeling features of ER/Studio Data Architect we can create automatic and customized data model diagrams. ER/Studio Data Architect provides functionality such as automatic layouts, custom colors and fonts for our objects, and relationship line control.

To make our model more attractive and easier to read, we can change the background, outline, and font colors along with the font type entities/tables, attributes/columns, views, and relationships in our data model. We can use specific colors and/or fonts to help us organize our data model.

In this blog post, I’ll share a macro which shows how to manage the colors from a script. With this macro, we can search for a string and colorize the attributes and columns which match the string.

wColorize
wColorize

If we want to search in other properties or objects, it would be quite easy to update the script to get exactly what we need.

Steps

First, we’ll need to create the macro within our ER/Studio Data Architect. If we’re unsure how to do this, a tutorial video is provided at the end of this post, demonstrating the process.

Then, we select the model which contains the Attributes and/or Columns we want to change their colors.

Finally we run the macro and we use the provided UI:
