I have been struggling with bringing a large dataset from an outside database into CDS while maintaining the relationships between the tables.  It has even been stated that it is impossible to do it. https://powerusers.microsoft.com/t5/Common-Data-Service-for-Apps/Creating-Parent-Child-Relationship-... In this article, I will show a step by step method for accomplishing this with illustrations of the steps.  It might be cumbersome but it is possible just using Excel with the built in Power Query, PowerApps Common Data Service.  Kudos goes to @SeanHenderson  for the original idea. 

In this article I will show you how to create a re-usable calculator control component in PowerApps. We will use buttons and text label controls to create a responsive calculator as a custom component with low code no code.

Hi all,

FYI, experimental release of the PowerApps component framework for Canvas apps is now available. With PowerApps component framework, developers can now develop their own code components and use them inside canvas apps in addition to model apps.

This is a great opportunity for professional developers to extend an industry-leading Enterprise Low-Code Application Platform  by creating reusable code components which all Makers can use.  Possibilities are endless when the modern web technologies and the 3rd party libraries can be utilized inside our powerful low-code, high productivity application platforms that empower every developer to achieve more.

For details please see annoucement blog post here.
