Having worked in data analysis for the past three years and eager to acquire new skills for career growth, I've decided to start learning SQL. I plan to share my journey through a new blog series, allowing us to learn together in a collaborative way.
i have decided to post a blog once in two or three days, as i start learning new topic and explain you, what are all the challenges that i encounter while leaning, and how to use various online tools to practice each topics, along with few documents and manuals to help you in the process.
