Getting Started — PostgreSQL 18 Course Roadmap

Relax. We'll talk through this in plain words — no textbook voice.

What you'll walk away with

Explain the core ideas behind Getting Started — PostgreSQL 18 Course Roadmap
Run the sample SQL or command and verify its output
Apply the technique to the Tutorial Platform and production scenarios

Build the mental model

PostgreSQL is an open-source relational database with strong SQL support plus production features such as transactions, JSONB, full-text search, extensions, and replication. The course references PostgreSQL 18.6, while most core SQL and design concepts also apply to supported versions 14 through 18.

Connect it to a real scenario

Throughout the lessons you will grow one `tutorial_platform` database. Users, tutorials, lessons, enrollments, progress, and comments will connect into a capstone that also includes a Node.js API, backups, monitoring, and a deployment plan.

PostgreSQL combines a relational SQL database with production capabilities
The course targets PostgreSQL 18.6; core lessons broadly work on 14–18
One project grows continuously from the basics to production

Try the working example

text

Basic SQL → Data modeling → Transactions & indexes
→ Performance & security → Tutorial Platform project
→ Backup, monitoring, and production readiness

You should see

You can explain the learning path and the system you will build.

5-minute try-it

Choose an application you want to build with PostgreSQL and list five entities it must store.

One important caution

Do not treat PostgreSQL as only a book of SQL syntax. Connect every query to data integrity, concurrency, and operational impact.

Easy traps

Do not treat PostgreSQL as only a book of SQL syntax. Connect every query to data integrity, concurrency, and operational impact.
Validate sample code on a local or test database with recoverable backups before applying it to production data.

Exercise

Choose an application you want to build with PostgreSQL and list five entities it must store.
