Data Trust › Scenario Studio › Scenario Builder

Validation using Custom Business Rule

Create a custom SQL-based validation rule for domain-specific data quality checks.

Overview

A Custom Business Rule validation scenario applies a user-defined SQL expression or logic expression to validate data quality beyond the standard built-in rule types. Custom rules give maximum flexibility for domain-specific data quality requirements.

Note: Ensure all required connection profiles are configured in the Administration module before building this scenario.

Prerequisites

• You are logged in to Data Trust with a Pro-User or Admin Pro-User role.
• An RDBMS connection profile is configured and the custom rule SQL has been reviewed and tested.

Steps

Path: Data Trust › Scenario Studio › Scenario Builder › Validation using Custom Business Rule

Figure 1: Validation Option

Navigate to the Scenario Studio module and select the Validation using Custom Business Rule option from the left sidebar or main menu. This opens the scenario builder canvas where you will configure the data source connections, transformation rules, and execution settings.

Figure 2: Drag and drop RDBMS Widget

Drag the Rdbms Widget from the widget palette and drop it onto the scenario canvas. Positioning the widget opens its configuration popup where you will set the connection, table, and any additional options.

Figure 3: Select connection and click on navigator

Select the appropriate connection from the dropdown to link this widget to its data source. Choosing the correct connection profile ensures the scenario reads from or writes to the intended database or file system.

Figure 4: Select table

The Navigator panel displays the available databases, schemas, and tables for the selected connection. Expand the tree to locate the required table or view, then click Select to add it to the widget configuration.

Figure 5: Click on Validation Rules Tab

The Validation Rules tab lists all available business rule widgets that can be applied to the selected dataset. Drag the required rule widget onto the canvas, configure its threshold or pattern, then save before moving to the next step.

Figure 6: Custom Busines rule popup

The Custom Busines rule popup dialog exposes all available configuration options for this step. Review each field carefully and fill in the required values before clicking Save or OK to apply the configuration.

Figure 7: Default it will select Data Eliment

This step involves interacting with the Default it will select Data Eliment within the Validation using Custom Business Rule workflow. Follow the on-screen prompts to complete this step before proceeding to the next configuration stage.

Figure 8: Custom Business rule using Constent

The Validation Rules tab lists all available business rule widgets that can be applied to the selected dataset. Drag the required rule widget onto the canvas, configure its threshold or pattern, then save before moving to the next step.

Figure 9: Business Rule Using Or Condition

The Validation Rules tab lists all available business rule widgets that can be applied to the selected dataset. Drag the required rule widget onto the canvas, configure its threshold or pattern, then save before moving to the next step.

Figure 10: Additional Settings

The Additional Settings panel provides advanced configuration options such as custom SQL filters, join conditions, and performance tuning parameters. Configure only the settings relevant to your scenario — leave optional fields at their default values unless a specific behaviour is required.

Figure 11: Drag and drop Email widget

Drag the Email Widget from the widget palette and drop it onto the scenario canvas. Positioning the widget opens its configuration popup where you will set the connection, table, and any additional options.

Figure 12: Email Configuration

The Email widget sends an automated result notification to configured recipients after the scenario finishes executing. Provide the recipient addresses, subject, and choose whether to attach the exception report or include a summary in the email body.

Figure 13: Click on Execute Button

Click the Execute button to trigger the scenario and begin processing data from the configured sources. The scenario transitions to Monitor mode where you can track real-time execution progress and view interim results as each step completes.

Figure 14: Scenario executed

Click the Execute button to trigger the scenario and begin processing data from the configured sources. The scenario transitions to Monitor mode where you can track real-time execution progress and view interim results as each step completes.

Figure 15: Validation Execution Summary

The Validation Execution Summary page presents the full outcome of the scenario execution including record counts, match rates, and any detected exceptions. Drill into exception records to inspect individual mismatches and use the Export to CSV option to share results with stakeholders.
