Developer's Guide to PostgreSQL on Linux: psql shell

This is the second article of a series featuring a collection of useful tasks for administering PostgreSQL version 11 on the Linux operating systems Ubuntu 18 LTS as well as CentOS 7. For those unfamiliar, PostgreSQL is a powerful and robust Object Relational Database which is freely available as open source software and widely popular. In this article I introduce the psql interactive shell using the default postgres user.

This is the third article of a series featuring a collection of useful tasks for administering PostgreSQL on the Linux operating systems Ubuntu 18 LTS as well as CentOS 7. For those unfamiliar, PostgreSQL is a powerful and robust Object Relational Database which is freely available as open source software and widely popular. In this article I show how to create databases using both SQL statements along with the createdb utility program.

Developer's Guide to PostgreSQL on Linux: Creating Accounts and Making Connections

This is the third article of a series featuring a collection of useful tasks for administering PostgreSQL on the Linux operating systems Ubuntu 18 LTS as well as CentOS 7. For those unfamiliar, PostgreSQL is a powerful and robust Object Relational Database which is freely available as open source software and widely popular.

Developer's Guide to PostgreSQL on Linux: Changing the Default Data Directory

In this fifth article demonstrates how to change the default data directory of a PostgreSQL database cluster running on the Linux Ubuntu 18 LTS and Centos 7 operating systems. This article shifts focus to improving the scalability, robustness and, performance made possible by moving the data directory to it's own area of the file system. Isolating the data directory also reduces file access contention with other OS activities and allows for easier resizing.

Introduction to Redshift using Pagila Sample Dataset Including ETL from Postgres using AWS Glue

In this article I give a practical introductory tutorial to using Amazon Redshift as an OLAP Data Warehouse solution for the popular Pagila Movie Rental dataset. I start with a basic overview of the unique architecture Redshift uses to accomplish its scalable and robust use case as an enterprise cloud data warehouse. Then armed with this basic knowledge of Redshift architecture I move on to give a practical example of designing a schema optimal for Redshift based off the Pagila sample dataset.
