BUILD

What you'll build

Spin up PostgreSQL in Docker and control it with plain English. Build a real e-commerce database with 40,000+ rows.

1. Install Docker + connect Cursor

Install Docker Desktop to run databases cleanly. Connect Cursor to Docker through MCP settings so you can control everything with plain English

2. Create PostgreSQL container with chat

Tell Cursor to 'create a PostgreSQL database' and watch it happen. No complex commands needed. MCP translates your words into perfect Docker setup

3. Load 40K rows of demo data

Import realistic e-commerce data with one command. Get 2,000 customers, 1,000 products, 10,000+ orders ready to explore

4. Query your database by chatting

Ask questions like 'show me gold tier customers' and get instant results. Learn SQL by watching Cursor write perfect queries from your plain English

5. Visualize schema with AI

Generate visual maps showing how your tables connect. See the relationships and patterns used by real production databases

I recently got a new job, and I can't thank NextWork enough. Working on the projects helped me build real skills that employers actually care about.

FAQs

Everything you need to know

No. This project is designed for complete beginners with zero coding experience. MCP handles the technical complexity - you give instructions in plain English, and it writes the commands. We guide you through every step with clear instructions and screenshots. You'll install tools, connect services, and build a working database all through natural language prompts. By the end, you'll have hands-on database experience without writing a single line of SQL.

You need a computer with internet access. We'll guide you through downloading Cursor (a free AI code editor) and Docker Desktop (free tier with no credit card required). Both tools offer generous free tiers suitable for learning. Cursor runs on macOS, Windows, and Linux. You'll also install uv for Python packages, which we walk through step-by-step. No prior experience with Git, databases, or development tools required.

Most learners complete this project in 60 minutes to 90 minutes. The project is broken into 4 main steps - setting up your development environment (15 minutes), configuring MCP servers (10 minutes), building the database with 40,000+ rows (30 minutes), and optimizing performance (5 minutes). You can work at your own pace and take breaks whenever needed. All progress is saved locally. If you get stuck, join the NextWork Discord community for peer support and mentorship from experienced developers. It's active 24/7 with support from other learners and NextWork team members.

You'll build a complete PostgreSQL database in Docker with 40,000+ rows of e-commerce data. The database includes 2,000 customers with tier levels (bronze/silver/gold/platinum), 1,000 products across categories, 10,000 orders with statuses, and 30,000+ order items. You'll also learn to spot slow queries and add indexes that make everything 10x faster. This is portfolio-worthy work. You'll have a functioning database with real performance optimizations you can demonstrate to employers or add to GitHub.

MCP is a connection standard that lets AI assistants like Cursor interact with external tools and services. Think of it as a universal translator - it allows Cursor to "talk" directly to Docker and PostgreSQL. In this project, MCP acts like a control tower. You describe what you want in plain English and the MCP handles the technical translation. Instead of learning SQL syntax or Docker commands, you say "create a database with users table" and it happens. This represents a major shift in how developers work - natural language becomes your programming interface.
