Build practical database development skills with PostgreSQL for Developers Training, a comprehensive course designed for software developers, backend developers, application engineers, database professionals, and IT specialists who want to confidently build, and support applications powered by PostgreSQL.
Duration 5 days – 35 hrs
Overview
The PostgreSQL for Developers Training course provides a practical, developer-focused introduction to using PostgreSQL as a database platform for modern applications. Participants will develop the knowledge and hands-on skills required to design relational databases, create efficient database structures, write SQL queries, manage application data, and integrate PostgreSQL with backend applications.
The course begins with the fundamentals of relational database design and PostgreSQL, helping participants understand how databases, schemas, tables, relationships, data types, and constraints work together to support reliable applications. Learners will explore practical database design principles and develop a strong foundation for creating structured and maintainable PostgreSQL databases.
Participants will then build practical SQL programming and database development skills, working with data retrieval, filtering, sorting, joins, aggregate functions, subqueries, and data manipulation operations. Through hands-on exercises, learners will gain experience writing SQL queries that support common application and business requirements.
The training also introduces important PostgreSQL development practices, including primary and foreign keys, database relationships, views, roles and permissions, data integrity, transactions, backup and recovery, and basic database security. These concepts help developers create applications that interact with databases safely and reliably.
A key component of the course is PostgreSQL application integration using Node.js. Participants will learn how to establish a connection between a PostgreSQL database and a Node.js application and perform common CRUD (Create, Read, Update, Delete) operations. This provides practical experience connecting database development with backend application development.
The course emphasizes hands-on learning through practical exercises and real-world development scenarios. Participants will apply PostgreSQL concepts throughout the training rather than simply studying database theory, helping them understand how database design and application development work together.
By the end of the PostgreSQL for Developers Training, participants will be able to design and work with PostgreSQL databases, write practical SQL queries, manage application data, and integrate PostgreSQL with Node.js applications. The course provides a strong foundation for developing reliable, maintainable, and database-driven applications and progressing toward more advanced PostgreSQL development and database administration skills.
