1. What are Power Apps?

Power Apps is a set of apps, services, adapters, and data platforms that work together to create an agile development environment for creating unique software that meets business needs.

2. What are the features of PowerApps?

PowerApps, like Flow and other Office 365 automation technologies, has capabilities and tools to let you create apps without coding. These are some of them:
   A collection of more than 200 connectors for integrating data and systems across the Office 365 universe
  A simple drag-and-drop interface for app construction.
  Tight connectivity with other Dynamics and Office 365 tools.
  There is robust support infrastructure in place, including a strong PowerApps community. 

3. Is it feasible to develop PowerApps without having a licence?

By joining up for a 30-day PowerApps trial plan, you may try out all of the features for free. If you don’t have a Power Apps licence, the trial plan gives you temporary access to the following features:
  It extends Office 365’s capabilities (SharePoint Online, Teams, Excel, and more)
  Model-driven apps can be created and run With Power Automate, you can create automated workflows.
  Create and administer Dataverse databases and environments                                   

4. What are the major components of PowerApps?                                                      

Power Apps is a high-productivity business app development platform with four primary components:

  •   Canvas apps.
  •   Model-driven apps.
  •   Portals.

  Microsoft Dataverse.

5. Difference between Canvas and Model Driven Apps.

Canvas Apps: Canvas apps, on the other hand, start with the user experience and allow for customization through various UI features such as charts, media, drop-down lists, text-input boxes, labels, and more. You may also create canvas apps for use on the web, mobile devices, and tablets.                            Model-driven Apps: To create a significant app, model-driven apps use a component-based methodology. Dashboards, business processes, forms, charts, views, and entities are some of the components that make up a user interface. Model-driven Apps begin with your data model, which will be built up from the shape of your core business data and processes in the CDS to model forms, views, and a variety of other components.

6. What are the main components of Power Apps?

The main components of Power Apps that one needs to understand before developing an app are

  •   GALLERY: A gallery in the app is a way to visualize data. It is a set of displays used to view and navigate data.
  •   SCREEN: A screen is a method of visualizing a specific data collection or record (mobile, iPad, Desktop). There usually is one for seeing all records, one for viewing a single record, and one for editing.
    •   CARD: A card is a screen area that displays a specific record from your SharePoint list or any other database from which you built an app. 
  •   CONTROL: Controls allow you to see and interact with your records.
  •  PROPERTY: Each control has its own set of properties.
    •  FUNCTION: Functions are used to interact with and change the characteristics.
7. In PowerApps, how can separate user environments be created?

The location where data, apps, and business processes are stored, managed, and shared is referred to as an environment. It can also be thought of as a container that separates apps according to their target audiences, security requirements, and responsibilities. Creating or selecting the environment to be used, on the other hand, is mostly dependent on the company and the apps you intend to develop.

8. how do you define or use a local or global variable? 

The Set function is used to set the value of the global variable. This stores a piece of data momentarily, such as the outcome of operational data or the number of times a button has been pushed. The content variable is then created using the UpdateContext function, which temporarily stores information. Context variables (also known as local variables) are exclusively available on that screen; the value cannot be accessed from any other screen.

9. How can PowerApps benefit your company?

Workflow, automation, data visualisation and reporting, collaboration, and other activities may all be handled using PowerApps. Teams, field workers, your management team, and even your consumers could be involved. The use cases might range from the simple to the complicated. You can improve your fundamentals while simultaneously being incredibly inventive. PowerApps can be accessed through a mobile app, a website, or an Office 365 product like Microsoft Teams

10. Is it possible to use several data sources in a single canvas app?

Any number of connections can be made using Power Apps, and once they’re made with an account, any number of data sources can be used in a single program. 

11. Flow reliant on Power Apps, or does Power Apps rely on Flow?   

 PowerApps is a new version of the solution that allows you to create a mobile-oriented app that is routed to SharePoint for forms. PowerApps extensively uses the Flow, but it is not essential. Flow, on the other hand, can use Power Apps and does so frequently as a frontend for its work, but it does not require them.

12. What kind of company should use Power Apps?       

Power Apps is designed for companies of all sizes. It will enable you to design apps that are tailored to your specific needs; this is true for small, medium, and large enterprises alike. This holds regardless of the industry in which your business operates.

13. Is it necessary to learn to code?

The Power Apps platform was created to allow anyone who isn’t a programmer to create their apps. As a result, learning to code is entirely unnecessary. To make things even easier, you can use one of the many pre-defined templates available in the PowerApps library. Then you can personalise it to create an application that is tailored to your requirements

14. What are some examples of Microsoft PowerApps Use Cases?

You may use Power Apps to construct applications that help you collect data more efficiently daily.Make an application that allows you to accomplish the following:

  •   Make it easy for your employees to enter information about their working hours.
  •   Allowing you to obtain expense accounts from each employee can help you manage expenses more effectively.
  •   Allows your subcontractors to submit control notes into your database directly (for example, for the regular checking of the condition of your equipment)
  •   Unlike traditional development, Power Apps has the distinct advantage of being able to be produced and released quickly. Companies now can respond to their customers’ needs swiftly and independently
15. What are PowerApps Portals, and what do they do?

Power Apps Portals, is more focused on website design. In simple terms, a Portal is to web design what a Canvas app is to app design.

  •   It’s a simpler approach for users to develop external-facing websites with a simple studio and expose data to customers and vendors (who can be guests and don’t need to check in).You may also play around with the CSS if you want to get a little more technical.
  •   Portals and model-driven apps have a lot in common in that they’re both built on Dataverse and have access to the same pool of Dataverse components (Views, Forms, and so on) as well as the same data
16. What is Dataverse?

Dataverse is a data platform included with Power Apps that let you store and model business data.

  •   Dynamics 365 apps (such as Dynamics 365 Sales, Customer Service, Field Service, Marketing, and Project Service Automation) is created on this platform.
  •   Your data is already in Dataverse if you’re a Dynamics 365 customer.
  •   Dataverse allows you to securely store and manage data in a collection of standard and custom tables, with the ability to add columns as needed.
17. What are the differences between Power Apps workflows and Power Apps pages?

All users can see the page. A workflow is solely visible to the user who developed it unless it has been shared with others. A Power App page can be viewed inside the Power Apps, however, a Power App workflow action cannot be viewed inside the Power Apps.

18. What exactly is the difference between Power Apps and Power Automate?

Power Apps is a declarative environment that uses connectors to enable content access through a customizable user experience. Power Automate is a workflow engine that uses the same connectors as Power BI to provide automatic content access.

19. What are two different types of Power Apps authentication?
OAuth-based authentication: It authenticates the app requesting access to the Power Apps service, removing the need for users to remember their Power App password or Office 365 account credentials. Power Apps handles all authentication and authorization. 
Password-based authentication: Power Apps supports both user name and password-based authentication, and the Power Apps developer can choose which kind to employ for Power Apps forms. This can be configured using Power Apps attributes (Form > Security Type).
20. What is the difference between the Combo box and dropdown in Power Apps?
Combo boxes and dropdowns are two Power Apps controls that are frequently used to offer a list of options to users.
Combo box: A control that lets users choose from options. Search and multiple selections are supported.
Dropdown: A list displays only the first item unless the user opens it.
21. What is a flow in Power Apps?

Flow in Power Apps allows you to respond to an event in one service (like SharePoint online) and then do something with the data in another service (such as Twitter).

22. What is the difference between Power Apps and logic apps?
Azure Logic Apps is a service that allows you to integrate apps, build workflows, and more. Power Apps are used to create graphical user interfaces. Since almost everything can be referred to as an application or an app, it’s not logical to suppose that all applications are similar in some manner.
