Build a strong foundation in database technology with PostgreSQL Database Basics Training, a practical course designed for beginners, aspiring developers, database professionals, data analysts, IT specialists, and anyone who wants to develop essential skills for working with PostgreSQL.
Duration 2 days – 14 hrs
Overview
The PostgreSQL Database Basics Training course provides a practical introduction to PostgreSQL, SQL, and relational database concepts, giving participants the foundational knowledge needed to work confidently with PostgreSQL databases. As a powerful open-source relational database management system (RDBMS), PostgreSQL is widely used for web applications, enterprise systems, data platforms, and modern software development.
Participants will learn how PostgreSQL databases are structured and how to create, configure, and manage essential database objects. The course introduces PostgreSQL architecture, databases, schemas, tables, data types, relationships, and indexes, helping learners understand how structured information is organized and maintained.
A strong emphasis is placed on developing practical SQL skills in PostgreSQL. Participants will learn how to retrieve, filter, sort, and combine data using SQL queries, as well as perform essential data manipulation tasks such as inserting, updating, and deleting records. They will also work with primary keys, foreign keys, and other constraints to maintain data accuracy and integrity.
The course introduces essential PostgreSQL database performance concepts, including indexing and the use of EXPLAIN to understand query performance. Participants will gain an initial understanding of how database design and query execution can affect application and database efficiency.
Participants will also learn the fundamentals of PostgreSQL backup and recovery, including practical use of pg_dump and pg_restore. These skills provide a foundation for protecting database information and supporting reliable database operations.
Through hands-on exercises using PostgreSQL tools such as psql and pgAdmin, learners will apply the concepts covered throughout the course to practical database scenarios. By the end of the training, participants will have the foundational skills needed to create, query, manage, and maintain PostgreSQL databases and progress toward more advanced PostgreSQL development or administration training.
