GROCERY STORE MANAGEMENT SYSTEM
June 2021
Project: Grocery Store Management System
Program: C# Console Application
Project Goal: Creating a C# Application to manage inventory of a Dairy Department in a Grocery Store. Seeing firsthand how the orders were done at my previous job I figured I would make a system similar but with some differences and improvements.
Project Summary: This is a system for a Grocery Store Manager to view their products in an organized fashion as well as add any products to their daily truck delivery. This system is designed using object-orientated programming concepts as well as LINQ.
Project Tasks:
-
The first class that is designed and implemented is an abstract class called Product. The idea behind this class was that each different department in the store would inherit from this base class. This way they can implement any of their own properties/methods if necessary.
-
The class that inherits from Product is DairyProduct. This class has an additional static property to keep track of the number of pieces of the Dairy Truck.
-
The last class is Program which contains the Main method. All the Dairy Products are stored in a List data structure. When the Program is first run in Main it asks the user to either view the products in the dairy department or add to the truck.
-
Viewing your products option allows you to view different dairy products based on their type. LINQ Queries are being used to organize the products.
-
Add to the truck option asks the user to type out the product and how many pieces of the product to add to the truck. The Product that the user entered is filtered out of the List using LINQ and displayed. The truck number is updated once the product is found.
-
A fully functional menu system that allows the user to intermediately go through all the options throughout the duration of the program.
VIDEO GAME STORE SYSTEM
May 2021
Project: Video Game Store System
Program: C# ASP.NET Core MVC
Project Goal: Creating a C# Web Application Project to gain more experience with ASP.NET and related technologies.
Project Summary: Registering an account to add, delete, edit, and search for specific
video games in the system. Hypothetically, this will be used by the employees of the company to manage their inventory.
Project Tasks:
Implemented a personal C# ASP.NET Core MVC software project during extra curriculum activities.
Designed the Game class which have the properties of Id (Unique Identifier), Name, Price, and Genre.
Authentication was set to Individual User Accounts to create the database and set up the necessary tables for the user accounts.
Developed inventory management which allowed users to add, delete, edit, and search for specific products in the system.
Learned and mastered organization’s servers such as the MSSQL Server.
Implemented data migrations to create the necessary database tables.
Efficiently created an object-relational mapper to generate the Game table off the Game class.
APPLE CARD PROGRAM
Spring 2020
Project: Apple Card Program
Program: Java Console Application
Project Goal: Creating a Java Application that deals with credit card transactions, such as updating balances, validating card number and purchases, and storing all the data in txt files.
Project Summary: A Java console application acting as an Apple Card login page for
Apple customers to record their transactions.
Project Tasks:
Was the sole Software Designer and Developer for this school project.
Designed and implemented the Customer Class and Transaction Class with the necessary attributes within the scope of my project. The Card Number acts as a Foreign Key in the Transaction class which references the Card Number in the Customer Class.
The AppleCard Class contains all the methods that this class can do such as validateCard, processTransaction, etc.
The AppleCardSystem contains the main method which makes an instance of AppleCard and then calls the appropriate methods in the order I designed.
Two separate txt files were made for each class to retrieve and store data about the Customer and Transaction.
Implemented credit card validation for the Card Number as well as for the Balance.
Implemented necessary exception handling to display specific error messages to the user for loading a file, writing to a file, etc.
