Introduction Name: Nick Arneson School: Second year student at Southeast Technical Institute Enjoys: C# Networking Building custom computers Playing video games in free time

Project Description My project combines an end of day calculator for closing out the till at the end of day. It also focuses on using a database for managing special ordered parts for our clients. It will be used primarily by our store only at first, with hopes to integrate it into the other 40+ stores.

Key project tools Visual Studio 2019 Enterprise Edition Used for IDE Coding in C# MS SQL Express 17 For Database MSSQL Sever Management Studio 18 (SSMS) For Database management

Features & functions IsValidData() This function ensures the user is inputting the correct data into the End of Day calculator. The main feature is displaying Green text for the amount that needs to be pulled from the drawer Or Red text for money that is short in which you need to recalculate. Black text will mean no changes to the till need to be made.

Key input/output captures Top Image Shows the negative amount in the till for what is expected. Which in our case is $500 Bottom Image The application now displays an gain in change. The $42.05 will need to be removed to keep the till flush.

Database ERD Diagram Accounts and Vendors share a one to many relationship with each type of special order that can be placed. I thought about splitting Vendors, but decided against it, but I could more than likely create a more refined Vendors list. Added Access_Levels and Users tables, for an end goal of restricting certain to certain tasks. Example: Admin level has access to everything (Add users + below) Purchasers have access to add Vendors + below Users have access to add Customers.
