A Step-by-Step Guide to Angular Concepts



About Angular: I commenced writing about AngularJS 1.5, but for the duration of the 2 years watch for ASP.NET Core to be done, the vNext of Angular went from Alpha to Beta to launch of Angular 2, and later even to the releases of v4 and v5. So chapter 3 went through one complete rewrite and a few smaller ones.

The following is an extract of Chapter 3 about Angular, introducing the rules of the framework.

Angular Concepts

Angular is an internet software framework developed and maintained by way of Google and the open-source community. The framework has many features, like two-manner records-binding, templating, routing, components, dependency injection, and so on. 

Unfortunately, like every framework of its breed, it has a pretty steep mastering curve because of the many ideas you have to grasp a good way to be fluent in it. Here is a list of the maximum crucial Angular principles:

Modules: Containers that group together blocks of functionalities that belong together, like components, directives, offerings, and so on.

Components: Define the behavior of a "portion" of the screen.

Templates: HTML files that define how the view for an issue is rendered.

Data binding: The procedure that connects a factor to its template and allows information and occasions to drift between them.

Directives: Custom attributes that beautify HTML syntax and are used to attach behaviors to specific factors on the page.

Services: Reusable functionalities that might be independent of the views.

Dependency injection: A way to deliver dependencies (offerings maximum of the time) to classes (other services or components).
Metadata: Instructs Angular on how to method a class, whether it's a component,

 A module, a directive, which services ought to be injected, and so on.
Those phrases may sound summary at the moment, however... All of these principles are used to construct a... Single-web page application.

Installing the On-Premises Data Gateway in Power BI

Image
The On-Premises Data Gateway, originally to as the Power BI Enterprise Gateway, is a Windows service that runs in on-premises environments. The sole purpose of the gateway is to support secure (encrypted) and efficient data transfer between On-Premises data sources and MS Azure services such as Power BI, PowerApps, MS Flow, and Azure Logic Apps via an outbound connection to the Azure Service Bus.  Once installed, a gateway can be used to schedule data refreshes of imported Power BI datasets and to support Power BI reports and dashboards built with DirectQuery Power BI datasets and those that use Live Connections to  SSAS  ( SQL Server Analysis Services ) databases.  A single On-Premises Data Gateway can support the refresh and query activity for multiple data sources, and permission to use the gateway can be shared with multiple users. Currently, the gateway supports all common data sources via scheduled imports (including ODBC connections) and many of the most common sources

Is Power BI available for Mac?

Image
Microsoft Power BI is a commercial enterprise application that allows customers to install graphs, reports, and other visualizations for their facts. BI customers can then proportion and annotate their records with the software program. It might sound just like spreadsheet applications, however, it’s not entirely the same as customers don’t want to set up spreadsheets. Windows Power BI is freely available for download, but customers will want to enroll in Power BI Pro at $9.99 a month to absolutely utilize the service. Is Power BI available for Mac? There isn’t a Power BI Mac model that customers can make use of on Apple computer systems and laptops. So, users cannot download BI for Mac systems. Users have asked on the Power BI discussion board that Microsoft release a BI application install for Mac. A Power BI program manager spoke back as follows: We are not thinking about bringing Power BI Desktop to Mac each time soon; however, we do plan to bring more and mor
