Microsoft Dataverse, formerly known as Common Data Service, is an intelligent data platform that allows businesses to store and manage their data that is used by business applications. It offers an integrated set of tools to securely manage data and business logic within a secure and compliant environment. The Microsoft Power Platform Fundamentals exam (PL-900) covers this area and it is crucial to understand the business logic behind Microsoft Dataverse to perform well in the exam.
What is Business Logic in Microsoft Dataverse?
Business logic in Microsoft Dataverse refers to the application rules or procedures that determine how data is created, displayed, stored, and changed. It is the part of the programming that encodes the real-world rules that allow the software and data to mirror an actual business appropriately. This can be a simple rule like “an order can be placed only by a registered customer” or a complex algorithm that determines a process workflow.
Microsoft Dataverse uses business logic to control the integrity of data. It includes:
- Business Rules: These are self-contained units of business logic that can be exported or imported with the application.
- Business Process Flows: They provide a guide for people to get work done. They provide a streamlined user experience that leads people through the processes their organization has defined for interactions that need to be advanced to a conclusion of some sort.
| Business Rules | Business Process Flows |
|---|---|
| Define instructions based on actions or value changes | Provide a visual guide to follow during a work process |
| Works on both web application and mobile offline mode | Works on both web application and mobile offline mode |
| Doesn’t require any coding | Visual designer to model and automate your process flows |
Examples of Business Logic in Microsoft Dataverse
Let’s consider we have a sales application in a business context. Here, the business logic might include workflows like:
- Calculating Discounts: If a customer orders more than 10 items, they receive a 10% discount on their whole order.
- Flow of Approval: An order of more than $5000 must be approved by a supervisor.
Both of these workflows can be implemented by the use of business rules and business process flows in Microsoft Dataverse.
In the first example, you could set a business rule in the Microsoft Dataverse to automatically calculate the discount when the order quantity exceeds 10.
For the second example, you could create a business process flow to guide users through the approval process when the order exceeds the $5000 limit.
Business logic is thus an integral part of the Microsoft Dataverse that not only keeps data integrity but also influences the user interaction and workflow with the applications. As a part of PL-900 Microsoft Power Platform Fundamentals curriculum, a thorough understanding of business logic in Microsoft Dataverse provides a substantial grasp of data structuring and process automation.

Interview Questions
What is Microsoft Dataverse?
Microsoft Dataverse is a cloud solution from Microsoft that provides a unified and simplified data schema so that the data can be quickly and easily shared across apps and business processes.
What is the purpose of business logic in Microsoft Dataverse?
Business logic in Microsoft Dataverse is used to define the specific processes for tasks, actions, or events within your app that happens behind the scenes. It specifies and manages the behavior of the data, such as defining field behavior, validation, default values, etc.
How can you implement business logic in Microsoft Dataverse?
Microsoft Dataverse allows you to implement business logic using tools such as Power Automate, business rules, or by writing plug-ins using .NET development tools.
What is Power Automate in the context of Microsoft Dataverse?
Power Automate is a tool in Microsoft Dataverse used to automate workflows between applications and services. It allows creation of automated processes, guided tasks, or even complex aggregations of business logic.
What is the function of business rules in Microsoft Dataverse?
Business rules in Microsoft Dataverse offer a way to implement business logic at the field level without needing to write code. They can be used to set field values, show or hide fields, enable or disable fields, and validate data input.
What are plug-ins in Microsoft Dataverse?
Plug-ins are custom business logic (code) that can be triggered by events in Microsoft Dataverse. They can lend to the flexibility and robustness of your apps by adding to or modifying its standard behavior.
How is business logic evaluated in Microsoft Dataverse?
When an event occurs, the business logic in Microsoft Dataverse is evaluated based on the sequence in which it was set. If there are any conflicts, Server-side logic will override Client-side logic.
How does Microsoft Dataverse ensure data integrity?
Microsoft Dataverse ensures data integrity by using business logic to enforce rules and requirements. For example, you can set required fields, set minimum or maximum values, or validate text patterns to ensure that data is entered correctly.
What are some examples of how you can use business logic in Microsoft Dataverse?
Examples of using business logic in Microsoft Dataverse include requiring certain fields before a record can be saved, setting a field value based on another field’s value, or automatically sending an email when a certain event occurs.
Can plug-ins and business rules coexist in Microsoft Datavarse?
Yes, plug-ins and business rules can coexist. They can even respond to the same events and can complement each other in implementing business logic. However, it’s important to note that these entities have a certain sequence in which they are evaluated, and that can influence the end result.
What languages can be used to write plug-ins for Microsoft Dataverse?
Plug-ins for Microsoft Dataverse can be written in any language that supports the .NET Framework, such as C# or Visual Basic.
How are business rules in Microsoft Dataverse applied across different clients?
Business rules created in Microsoft Dataverse are applied consistently across all clients without needing any separate scripting or re-implementation.
