Building The JBoss BRMS Cool Store Demo (Lab 4 - Creating a Domain Specific Language)

Free Resource

Build APIs from SQL and NoSQL or Salesforce data sources in seconds. Read the Creating REST APIs white paper, brought to you in partnership with CA Technologies.

We are back with this weeks episode in the JBoss Business Rules Management System (BRMS) & Business Process Management (BPM) Suite online workshop series.

In this workshop we will be introducing you to the possibilities that abound for your business when leveraging these two new and exciting products.

Each week we will push out the next installment of this workshop that will lead you through building an online retail web shopping cart application, leveraging rules, events, and a rule-flow.

This project is available as a completed project called the Cool Store Demo, but we thought it would be interesting to help you build this application from scratch.

The second half of the workshop will be taking you through the same type of exercise, but with the JBoss BPM Suite, where you will put together an application that leverages a process, integrates rules, leverages human tasks, allows you to design your own forms, and much more.

Last week we created the domain model.

Creating the Cool Store Domain Specific Language
This week you will be shown how to expand the Cool Store project with a Domain Specific Language (DSL) that will allow your business users to create a rule using natural language.

The weeks following will feed you a new set of exercises to help you to the next stage of development as you watch your very own Cool Store rise from the ground up.

All of the workshop materials will be hosted online with the help of OpenShift, so all you need is a browser to follow along.

You do not need to be a Java developer, as this workshop focuses on only the online product web dashboard experience as an analyst would interact with the product. The only technical deviation from this will be the initial installation of the product, but we have detailed instructions and it is a three step process that should not take you more than a few minutes.

So what are you waiting for?
