To get the most out of SQL, pick up the essentials for writing efficient and optimised SQL queries. From indexing strategies to query optimisation techniques, having a good grasp of these recommended practices will considerably improve the productivity of your data retrieval and manipulation. 

Tableau: Data Visualisation

Introduction To Tableau 

Tableau is a popular data visualisation tool that allows users to convert raw data into comprehensible and compelling visualisations. Designed with accessibility in mind, Tableau allows users (regardless of tech prowess) to easily create insightful charts, graphs, dashboards, and maps to present findings in a visually appealing manner via its interactive interface. Here is how the tableau interface looks like:

Creating Engaging Visualisations

Interactive Dashboards And Storytelling 

Further dive into Tableau’s dashboard and storytelling capabilities. For example, combine multiple visualisations into interactive dashboards that allow users to explore data from multiple angles. Effectively convey the intended message to your audience via compelling visual representations of data.
