在数据库中使用 SQL

The world runs on data. Everything from your bank account to when your next dentist appointment is. That’s a lot of data. If you had to go through each of your clients’ records by hand, you’d waste hours! You could put things in a database, but manually inserting the data for each client could be very labor intensive. And when you actually need to find something, combing through all that data would be difficult, especially if there are records in the millions.

Thankfully, there’s a language used by most databases around the world that can help. Structured Query Language or SQL allows you to easily navigate, insert, and manipulate data. This course will introduce you to the basics of SQL.

By the end of this course, you’ll be able to:

• Define SQL and its functions in databases
• Explain the advantages and disadvantages of using SQL, for example in database management systems such as MySQL

Why take this course?

Without coding experience, data navigation can be difficult. Thankfully, SQL requires no coding and is used around the globe. This course, suitable for business owners and analysts, goes over the basics of SQL and MySQL, so you can start using them to query databases.
