Solution Considerations before development

Before you build an application, you should have some thought and break down what you want to do before building. This process is often called "Solution Architecting". While we will not be taking a lot of time doing this, I would like to introduce you to the basics of it.

In our session case we will look at:

• The Frontend built with Powerapps, you can learn more on How to build a canvas app 
• The Middleware that allows us to run the background process of our Asset Manager solution. This can be configured by using Approval flows within Power Automate 
• The Backend allows us to store all the data from our solution and to achieve this we will Set up tables in Microsoft Dataverse

Business Rules

1. The employee must provide the Start Date, End Date, Course Name, Employee Email and Name (These are automatically picked up based on the signed in user) to submit a booking request.
2. New Booking Requests should default to a status of Not Actioned until a manager reviews it
3. Employees can view all the Not Actioned but cannot change the status of their request
4. Employees are not allowed to add/change request comments
5. The requestor email and name are only visible to the Admin
6. Employees can only view their own requests and not of other employees
7. Requestor/Employee name and email are automatically filled in
8. Employees can only view their own requests and not of other employees
