Why did I start to learn SQL?
I have five years of experience as a digital media planner in Korea. I've managed digital campaigns, utilizing local platforms like Naver—similar to Google search engine in Korea—and have run YouTube advertisements through Google Ads. While I've handled a lot of data, I've primarily relied on Excel for analysis. Now, I'm eager to work with larger datasets to uncover broader insights about products and services. That's why I've started learning SQL. There’s a local certification in Korea called SQLD, and I plan to earn that by the end of the year. This blog will document my journey of studying SQL. Let’s get started!
What is SQL?
Even though I understood the basics of SQL, I sought out more information to gain a deeper understanding. SQL (Structured Query Language) is a programming language used internationally for database manipulation. It allows us to extract and organize data from accessible databases. SQL helps unlock the potential of data by enabling us to manage and analyze larger amounts of information. It can be utilized in marketing, healthcare, business strategy, data science, and more. This means that SQL is widely used in fields where big data exists, and professionals in these areas must leverage data to achieve their goals. Learning how to utilize SQL will help us uncover insights and shape the future vision.
