PowerApps tutorials

As of 2020, we can assure that every organization is involved in the development of the applications based on user requirements. However, there would be programmers and non-programmers as well who are involved in software development. Hence, there are some of the platforms that make the work easier for non-programmers. Powerapps is one of the platforms that we are going to discuss in this article. In this article, you will gain an understanding of what is PowerApps, its importance, terminologies, advantages and disadvantages of using PowerApps, etc.

What are power apps?

Powerapps is referred to as a collection of programs, services, applications and data platforms that helps in the rapid development of the applications.

Significance of Powerapps:

Microsoft introduced Powerapps in order to overcome the below set of problems.

  • Expansion of business data: The business data is expanded across different systems and exceeded the firewall and SaaS cloud. As data is stored in various systems, we are not allowed to access the data from the application.
  • Lack of professional mobile app developers: As per some of the recent survey analysis, it is found that the demand for mobile app developers would increase at least five times when compared to the IT organization's ability to deliver. The primary reason for this situation to come across is the deficiency of professional mobile app developers who are capable of meeting the requirements.
  • App sharing and IT Activities: We all know that Mobile apps are distributed through app stores and mobile devices. This has come up with the establishment of an inheritance methodology to get the app onto the mobile device.

Categories in Microsoft Powerapps

As mentioned earlier, by using the Microsoft power apps, the users are allowed to build and personalize the business apps quickly, without depending on the IT Professionals and Programmers. 

Powerapps can be divided into three different categories. They are:

  • The App itself
  • Connections to your data.
  • Flows: Workflows thrown by apps.

The App itself:

Through Powerapps, there is flexibility where the users are allowed to create applications for mobiles, tablets or desktops. The apps are developed in such a way that they perform some general functions based on the template. The customization of apps can be more specialized and specific. PowerApp studio allows you to create and modify the layout the same as with the App. In addition to templates, it also helps you in developing the apps from scratch to get more adaptability that is concerning the application’s flow.

Connectors to the data:

Whenever you are creating an app through a template, Powerapps queries about data source that you would like to use  for your App, some of the accessible data sources are:

  • Salesforce
  • Dynamics 365
  • Sharepoint list

Let us take an instance where we would like to develop an application that is capable of performing some operations on the contacts of the client, then we will need to develop the application on that SharePoint.

In order to develop mobile applications through Powerapps, it will just take only a few clicks. In order to customize and prioritize the data, we can make use of the drag and drop mechanism. Once the app is created, you will have separate screens for browsing the records and displaying the details of documents.

Microsoft Flow:

Microsoft flow is referred to as the primary engine that will be running behind the apps you run. An app refers to the collection of many automated processes or workflows. An app is created to perform certain operations on the data. The flow will make us understand how our apps should perform these operations. In order to run our app on our device, we will need to install a Powerapps app in our system or machine.

Microsoft Flow is responsible for automating the various repetitive tasks, which will enable you to dedicate more time to essential tasks. Apart from the automation, you are also allowed to establish API connectors and gateways for traditional solutions through the sophisticated integration tools of Powerapps. Microsoft Powerapps is now being used in various industries like Manufacturing, Pharmaceuticals, Information Technology(IT) as it can automate any routine task.

Different Types Of PowerApps:

There are two different types of PowerApp called canvas apps and model-driven apps that are based on the common data service. They are mostly the same, however, they make use of the same builder UI and they also include the same objects that are available inside the builder. The only difference that exists between them is how you will start creating the app and the PowerApps pricing plan needed.

Canvas Apps:

Canvas apps are those apps that can be created with the basic plan.

Below are the different ways in which you can create a Canvas app.

  • You will need to start from scratch by creating a blank app. This may also require you to create everything in the app.
  • You will need to start from a template. We have at least a dozen pre-built canvas app templates that are now available. You are allowed to start working from any of these and customize them as needed.
  • You will need to start from a data source. This will allow you to build a simple application to view, add or edit data in a single table from almost any data source.

The last two options will build fully functional apps for you and are considered a great way to learn how things work so you can eventually build your own apps from scratch.

Model-Driven Apps: 

Model-driven apps are those apps that are based on the common data service and this will require you to plan 2 pricing tier. A model-driven app comes into existence when there is a need that you will need to depend on the CDS, which requires the business logic.
