8/11/2023 0 Comments Basic postgresql tutorial![]() Text data is increasingly important today, and search operations on text data is also gaining importance. Queries such as distance computation and area computation. And this also supports location based queries. Spatial data analysis allows you to specify geographic objects such as locations, lines, polygons, all on a geographic map. However, you can easily install the PostGIS extension for PostgreSQL to work with spatial data analytics. The core PostgreSQL installation does not support geographic queries. Spatial data analysis has become much more important recently as we have access to more and more geographic data. And finally, we'll see how transactions and transaction isolation levels work in Postgres. We'll see how we can configure and use triggers in Postgres. We'll see how we can perform full text search with linguistic support in Postgres. In this course, we'll focus on some advanced features that Postgres has to offer, including spatial data analysis. For example, you can do spatial data analysis with Postgres, as we shall do in this course. And PostgreSQL supports powerful add-ons for complex data types. It's reliable, robust, extensible and widely used and tested. PostgreSQL is the backbone of many production workloads. Just like other relational databases, Postgres has support for atomicity consistency, isolation and durability of transactions. PostgreSQL is ACID-compliant and it runs on all major operating systems, Windows, Linux and macOS. PostgreSQL includes a vast number of features to safely store and scale very complex data workloads. Here are some reasons why so many people around the world use PostgreSQL. PostgreSQL has been in development for over 35 years and has a strong reputation for reliability, feature robustness and performance. ![]() PostgreSQL is a powerful open source object relational database system. ![]() But before that, I'm going to give you a very quick overview of what exactly PostgreSQL is. in this movie, I'll give you an overview of the features of PostgreSQL that we are going to be covering. I just install Postgres and dive right into the advanced features. I expect that you've had some background working with this technology before. And finally, this is not an introductory course on PostgreSQL. I also assume that you're familiar with SQL programming and you don't need an explanation of how basic SQL queries work. Now, in this course, I do assume that you're comfortable with relational databases and you understand how these systems work. Now, before we take a look at what we're going to be covering in this course and discuss actual course contents, let's take a look at the prereqs that you need to have to make the most of your learning. Hi, and welcome to this course on Advanced PostgreSQL.
