Signing up

Process of getting started with Cloud BRMS is simple and straight forward.

1. Go to GoRules Cloud And Sign Up
2. Follow the instructions to log in
3. Create your organisation and open it

Create a project

Projects are workspaces for your organisation. They enable you to achieve better decoupling between teams. Each team can manage their own projects and have ownership of their work.

Log in to GoRules. You should land on the dashboard which contains a list of projects.

Create a project by clicking on the Create project button and filling in the details.

You can now open the newly created project to access the documents and other project related resources.

Create a decision

Decisions are graph based structures which allow you to compose multiple nodes.

From the documents, create a decision and name it Shipping decision.

Double-click on the decision document to open it.

Connect the graph

Let's build a simple graph which uses required nodes (input and output) and a decision table.

Drag the components from the right side and connect edges until you create a graph like the one below.

Edit the decision table

Decision tables allow you to create a set of conditions in a spreadsheet format. They consist of inputs and outputs. Both inputs and outputs consist of two data points:

• Label - Helps you describe what the field is supposed to represent
• Field - Selector that utilises ZEN expressions

Add fields and rows to create a decision table with the same structure as below:

The reference operator ($) is also used in the table. Passing it as a first argument in contains function allows us to check if one of the groups which customer belongs to is called "premium". Meaning that "premium" customers will receive free shipping!

The purpose of the last row is to have a default value in case no other rows match.

Save and publish the changes by clicking the Save and publish button.

Simulate

📘

You can simulate a decision even when the content is unsaved. This allows you to experiment and test
before saving the changes.

Click on Open simulator button from the decision to show the panel on the right.

The panel consists of request and response. In the request write the following JSON:

{
  "customer": {
    "country": "US",
    "groups": ["premium", "early-bird"]
  },
  "cart": {
    "weight": 10
  }
}

The decision correctly matches the provided input, and this premium customer will enjoy their free-cost shipping.
