DATA STRUCTUTE PROJECT #2: E-commerce Warehouse Inventory System

 

Project Scenario: E-commerce Warehouse Inventory System

Problem Statement: Design an inventory management system for an e-commerce warehouse that needs to:

1. Track products in real-time

2. Support fast lookups by product ID and category

3. Maintain products sorted by price for quick filtering

4. Manage inventory levels and alert when stock is low

5. Show product relationships (frequently bought together)

This project implements an Inventory Management System for an e-commerce warehouse using various Data Structures and Algorithms to efficiently manage products, track inventory, and provide real-time insights.

Key Features:

• Product Management (Add, Update, Delete)

• Real-time Inventory Tracking

• Low Stock Alerts

• Category-wise Product Filtering

• Price-based Sorting & Searching

• Product Relationship Management (Frequently Bought Together)

2. System Architecture

The system is built using the following Data Structures and Algorithms:

Component	Data Structure/Algorithm	Purpose
Product Lookup	HashMap (ConcurrentHashMap)	O(1) access by Product ID
Price-based Sorting	TreeSet (Red-Black Tree)	Maintains sorted order by price
Low Stock Alerts	PriorityQueue (Min-Heap)	Efficiently tracks low-stock items
Category Index	HashMap<String, List<Product>>	Groups products by category
Product Relationships	Graph (Adjacency List)	Tracks frequently bought together items
Price Filtering	Binary Search	Efficient range queries
Sorting	QuickSort	Alternative sorting method
