Data is Everywhere

It is not a secret that data is everywhere; data is collected, processed, and accumulated in massive databases across all industry domains. As the technologies for handling data are evolving rapidly, the industry challenge is more focused on data utilization than data collection and storage. As a result, many organizations are looking for the right mix of people, tools, and products to help them pick up those piles of data, extract valuable insights and constantly gain market advantage.

The complete training program is divided into multiple sequential levels to let you grow your knowledge and understanding of SQL and data analysis.

Level 2 is a direct continuum of the topics we learned in level 1. It will extend your knowledge into more advanced SQL tools and capabilities. We will learn to combine data from multiple data sources, break complex queries into sub-queries, transform and classify data, analyze data with window functions, create views, CTEs, and more.

We will use quizzes and exercises to practice and sharpen your understanding of the learning objectives. In any case, I am here for any questions.

I wish you AWESOME learning and hope to see you inside!
