SQL and PostgreSQL: The Complete Developer's Guide

Stephen Grider connects relational-database fundamentals with features used by applications. Design patterns and query performance lead into concurrency, migrations and the way PostgreSQL stores information. It suits learners who want a substantial development-oriented course and are prepared to investigate why a query or schema behaves as it does.

What you will learn

• Design relational schemas for application features.
• Examine query efficiency and database storage.
• Explore concurrency and schema-migration decisions.

Who this suits

Learners starting SQL and PostgreSQL development; preview the programming examples and project requirements.

Before you enroll

Run examples in a disposable local database and keep sample data separate from production. Check PostgreSQL and extension versions before following setup instructions. Queries that work on a small example can behave differently as data grows. Inspect constraints, query plans and transaction behavior before applying an approach to a working application.
