The tools of business continue to change and grow. Long ago, paper and pencil replaced rote memory and more recently were themselves replaced by computers. Analysts used to work out calculations on calculators, then switched to spreadsheet applications, like Excel. Understanding SQL used to be a skill reserved for IT personnel; now, SQL is becoming an indispensable analytical tool in the modern workplace. Just like spreadsheets were once a tool known only to specialists but are now ubiquitous in the workplace, likewise SQL is beginning to become more accessible throughout organizations.
This course moves beyond the SELECT statement in SQL to basic constructions of creating and dropping database objects, importing into and exporting from the database, inserting into and deleting from the data tables, and updating the data. Many corporations require additional permissions in the database to allow someone to perform these operations, and as more and more analytics teams start working in databases, more businesspeople are being given these permissions.
I learned everything I know about SQL on the job, and so can you. After teaching for 10 years, I was pulled into IT at my first corporate position and have used SQL in every role since then. I know what it is like to learn a keyword for the first time, to start exploring its uses, to be shown tricks and techniques using it by others, and to eventually gain a deeper understanding of why it works the way it does. I have trained many others in SQL in companies large and small, including some Fortune 50 companies. I have compiled my experiences and curated from those lessons what I believe to be the important initial steps beyond simply selecting to share with you. I trust you will take this knowledge, and Spirit willing, share it with others.
