What is a DataMapper?

A DataMapper is a declarative ETL (Extract, Transform, Load) tool in OmniStudio that helps you:

• Extract data from Salesforce records.

• Transform data by applying formulas, mappings, and filters.

• Load data into Salesforce objects or external systems.

Types of DataMappers

1. DataMapper Extract - Retrieves data from Salesforce records.

2. DataMapper Transform - Modifies or reformats data as needed.

3. DataMapper Load - Inserts, updates, or upserts data into Salesforce.

4. DataMapper Turbo Extract - A faster way to extract data without transformations.

   
   
   
   

Best Practices for Using DataMapper

Before creating a DataMapper, it is important to follow best practices to optimize performance and maintain efficiency:

1. Minimize Data Retrieval: Select only the fields needed to improve performance and reduce processing time.

2. Use Naming Conventions: Follow a consistent naming structure for DataMapper and fields to improve readability and maintainability.

3. Optimize Transformations: Use DataMapper Transform only when necessary; avoid excessive transformations in Extract DataMapper .

4. Use Turbo Extract When Possible: If transformations are not needed, prefer Turbo Extract for better performance.

5. Leverage Formulas Efficiently: Instead of using multiple transformations, use formulas to manipulate data within a single step.

6. Limit Object Joins: Too many joins can slow down data retrieval. Extract only necessary related objects.

7. Test with Sample Data: Always preview and test DataMapper with sample data to ensure correct functionality before deployment.
