From Excel to SQL
During the course, I gained a comprehensive understanding of how to work with SQL to extract data from Excel spreadsheets. I learned how to write SQL queries to filter, sort, and aggregate data. Additionally, I learned how to use subqueries and joins to combine data from multiple tables and create more complex data sets. These techniques allowed me to better organize and analyze large amounts of data, making it easier to draw meaningful insights and conclusions. Overall, the course provided me with a solid foundation in SQL and data analysis, which I can apply to a wide range of professional and personal projects.
