In Microsoft Flow, an action is a task that can be performed within a workflow. An action can be used to create items, send emails, update records, or perform other tasks that are supported by the various connectors available. For example, an action could be used to send an email when a new item is created in SharePoint.

A trigger is what initiates the workflow and causes the actions to take place. Triggers can be set up to respond to events such as when a new item is added to SharePoint or when a file is uploaded to OneDrive. Triggers allow you to specify conditions that must be met for the workflow to begin executing its actions. For example, you could configure a trigger so that it only sends an email if certain conditions are met such as the item being created has specific values in certain fields.

What do you mean by collection in PowerApps?

Collection in PowerApps is a data source used to store and retrieve data. It is similar to a database table, but it exists only within the app. Collections allow you to store multiple records of data, such as customer information, product details, or any other type of data that your app needs to use. You can create collections from scratch, or you can connect them to an existing data source such as an Excel spreadsheet or a SharePoint list.

Once you have created a collection in PowerApps, you can then use it throughout the app. For example, you can display the contents of the collection in tables and galleries on your app screens, add formulas to calculate values based on the contents of the collection, and even filter and sort your collections for more specific results. Additionally, you can use collections with Flow to trigger automated processes when certain conditions are met.

Overall, collections are incredibly useful for storing and managing data within PowerApps apps.

Which types of companies should use Microsoft PowerApps?

Microsoft PowerApps is a great tool for companies that need to build custom business applications without writing code. It is especially useful for organizations with limited resources, as it allows them to quickly and easily create apps that can be accessed from any device.
