Implementing Data Sources and Collections

To effectively use Power Apps, understanding how to implement data sources and collections is crucial. Data sources are the backbone of any app, providing the raw data that your app will display and manipulate. Collections, on the other hand, are in-memory tables that are used within the app to store and manage data temporarily.

To create a collection that combines columns from two different data sources, you can use the Collect function. This is particularly useful when you need to display merged information from multiple sources without the need for a persistent storage. For instance:

Collect(MyCollection, DataSource1, DataSource2)

This will create a new collection named MyCollection that includes columns from both DataSource1 and DataSource2. Remember to define the schema of your collection to ensure that the data types are consistent and to avoid any potential issues during the app’s runtime.

When designing your app, it’s important to consider the scope and lifetime of your collections. Collections are cleared when the app is closed, so they are ideal for temporary data manipulation during a session.

Choosing the right data storage is also a key decision. SharePoint lists are great for simple data storage needs, while Microsoft Dataverse offers a more robust solution with complex data types and relationships. Here’s a quick comparison:
