Concepts
Introduction:
In the world of Microsoft Power Platform development, there are various options available when it comes to managing data tables. Each option serves a specific purpose and understanding the differences between them is crucial for successful application development. In this article, we will explore the use cases for standard tables, virtual tables, and connectors, enabling you to determine when to utilize each one effectively.
Standard Tables:
Standard tables provide a traditional approach to managing data within the Power Platform. These tables are created as physical entities within the Common Data Service (CDS) or Dataverse, allowing developers to define the schema, columns, and relationships. Standard tables are an ideal choice when:
- Defining a structured data model: Standard tables are the go-to when you need to create well-defined entities with strong relationships. They provide a solid foundation for developing applications that require complex data structures.
- Storing persistent data: If your application relies on storing data for extended periods, standard tables offer a reliable and robust solution. As permanent storage entities within the CDS, standard tables can hold large volumes of data securely.
- Implementing business logic: Standard tables support the usage of business rules, workflows, and plugins. With these capabilities, you can enforce data validations, execute automation, and integrate extended functionality within your application.
Virtual Tables:
Virtual tables bring a new dimension to data management in the Power Platform. Unlike standard tables, virtual tables are not physical entities and do not store data in the CDS. Instead, they utilize a querying mechanism to fetch data dynamically from external sources. Virtual tables are a suitable choice when:
- Querying external data sources: Virtual tables allow you to connect and retrieve data from various external sources such as SQL databases, SharePoint lists, and other connectors. By establishing a connection to the external system, you can leverage the data without duplicating it in the CDS.
- Enhancing performance and reducing data redundancy: When dealing with large datasets, virtual tables can significantly improve performance. By avoiding data replication and relying on real-time querying to external systems, you can minimize data redundancy and ensure data accuracy.
- Integrating with legacy systems: Virtual tables facilitate seamless integration with legacy systems that may not have native support within the Power Platform. By connecting to those external systems, you can utilize their data within the context of your application.
Connectors:
Connectors act as bridges between the Power Platform and various external services, applications, or data sources. They offer pre-built APIs or connectors that simplify integration without the need for custom development. Connectors are a practical choice when:
- Integrating cloud services: Connectors provide out-of-the-box integration with popular cloud services like Microsoft Dynamics 365, SharePoint, Azure services, and more. These connectors eliminate the need for complex coding and enable developers to focus on the core application logic.
- Leveraging APIs: Connectors offer a simple and standardized approach to consuming APIs from external services. With hundreds of connectors available, you can seamlessly connect to a wide range of applications, extending functionality and data processing capabilities.
- Enabling third-party integrations: Connectors provide an efficient method for integrating third-party applications and services. Instead of building custom integrations, developers can leverage connectors created by independent software vendors to connect to their applications.
Conclusion:
When it comes to Microsoft Power Platform development and data management, understanding the distinctions between standard tables, virtual tables, and connectors is essential. By carefully considering your requirements, you can determine the appropriate choice for your application. Whether it’s the formal structure and persistent storage offered by standard tables, the dynamic querying of external data through virtual tables, or the seamless integration with external systems via connectors, Microsoft Power Platform provides a rich set of tools to empower developers in managing their data effectively.
