Databases can connect to the internet, allowing millions of users to access them at the same time.Databases can interact with other programming languages such as Python, Ruby, or Java, allowing you to execute many more powerful tasks and queries with your data.Whereas Excel can handle up to 1 million rows of data, a database like MYSQL can handle over a billion rows. Databases can process more data than spreadsheets.Excel: What’s the difference?īoth a database and Excel organize data into rows and columns, but databases are more powerful than Excel spreadsheets for two reasons: SQL is a coding language for querying data in databases. The trend is clear: whether you’re a product manager, a business analyst, an MBA, or a developer - SQL will upskill your career. Community managers are learning HTML and CSS to send better formatted email newsletters, marketers are learning SQL so they can connect directly to their companies’ databases and access data, and financial analysts are learning Python so they can work with data sets too large for Excel to handle. The business applications for data analytics and programming are myriad. Mattan Griffel, adjunct professor at Columbia Business School, explains why everyone in business should learn to code SQL: While some of those roles may seem obvious, such as becoming a Software Engineer, there are plenty of other positions that require SQL that you might not expect. SQL is one of the most widely used programming languages in the world, and if you learn SQL, you open up some clear paths to finding new work and employment opportunities.
