Get Started with Grouped Decision Matrix
Learning Objectives
After completing this unit, you’ll be able to:
- Revisit the lookup tables.
- Sign up for a Developer Edition org with Business Rules Engine.
Before You Start
Before you start this module, consider completing the following recommended content.
Revisit Lookup Tables
In the Business Rules Engine module, you got to know that lookup tables are of two types: decision matrices and decision tables.
Decision matrices are lookup tables that contain user-defined input and output columns. When a process or tool calls a decision matrix, the Business Rules Engine locates the table row that matches the input values and returns the output value for that row.
Decision matrices are also divided into two broad types.
- Standard decision matrices: These matrices have common characteristics, such as input columns, output columns, and versions.
- Grouped decision matrices: You use these matrices to group a matrix’s data into different versions based on keys if several rows have the same column values.
Here are some advantages of using grouped decision matrices.
- These matrices are suitable for situations that involve using multiple similar matrices, such as matrices with the same input headers and the same output headers.
- These matrices improve data management and reduce storage requirements.
- These matrices help users to create and activate new versions of a matrix without affecting other versions.
Decision tables are lookup tables that read business rules with multiple inputs and return multiple outputs. A single lookup on a decision table can match multiple rows and return multiple output sets. In a decision matrix, however, a single lookup can match multiple rows but return only one output value.
In this module, you learn how to create and use a grouped decision matrix and a decision table.
Sign Up for a Developer Edition Org with Business Rules Engine
To complete this module, you need a special Developer Edition org that contains Business Rules Engine and our sample data. Get the free Developer Edition org and connect it to Trailhead now so you can complete the challenges in this module. Note that this Developer Edition org is designed to work with the challenges in this badge, and might not work for other badges. Always check that you’re using the Trailhead Playground or special Developer Edition org that we recommend.
- Sign up for a free Developer Edition org with Business Rules Engine.
- Fill out the form:
- For Email, enter an active email address.
- For Username, enter a username that looks like an email address and is unique, but it doesn't need to be a valid email account (for example, yourname@example.com).
- For Email, enter an active email address.
- After you fill out the form, click Sign me up. A confirmation message appears.
- When you receive the activation email (this can take a few minutes), open it and click Verify Account.
- Complete your registration by setting your password and challenge question. Tip: Save your username, password, and login URL in a secure place—such as a password manager—for easy access later.
- You're logged in to your Developer Edition.
Now connect your new Developer Edition org to Trailhead.
- Make sure you’re logged in to your Trailhead account.
- In the Challenge section at the bottom of this page, click the org name and then click Connect Org.
- On the login screen, enter the username and password for the Developer Edition org you just set up.
- On the Allow Access? screen, click Allow.
- On the Want to connect this org for hands-on challenges? screen, click Yes! Save it. You’re redirected back to the challenge page and ready to use your new Developer Edition to earn this badge.
This module uses USD as currency for the examples and hands-on challenges. Your Developer Edition org’s currency depends on the country and postal code you select on the sign-up page.
