Hello and sorry. I'm new to PowerApps and exploring it's functionality. It's a little overwhelming, and I am having a hard time finding information on what I want to do with PowerApps. I am hoping someone here might be able to point me in the right direction.

Basically, I want to create a portal for a business where employees can access it and quickly pull up data and update the data (rough diagram attached). I'm fairly certain, based on what I've read/watched about PowerApps/Pages this should be possible, but there is so much information out there that I am having a hard time finding a good starting point.

Any suggestions would be greatly appreciated.
