Out of 13 million new jobs that have been created in the United States in the last 10 years, have required skills in technology. And as the future of work moves forward, the tech skills necessary to succeed in these new roles will only become more advanced. Skilled workers need to be able to work with technology beyond an internet browser or word processing application. over 8.5 million Jobs like Human Resources (HR), that never seemed to need technology before, are now specifically looking for applicants with skills in . In a survey done by , over half of survey responders data analysis when hiring for their HR department. data analysis SHRM require Data — when collected, stored and analyzed — can be useful for making decisions in almost every department of a business. But how is the data collected, stored, and analyzed? That’s where SQL comes in. What is SQL? SQL is a query language specifically for managing data in relational databases, where data is stored in tables with clear relationships between data points. SQL can be used to clean and normalize data, read values, analyze data from multiple sources, and even manipulate data. Mal Sridhar, a Product Manager (PM) at Waymo (and also an instructor for Udacity’s ), says that are used for the self-driving cars at her company. Every autonomous vehicle at Waymo collects extremely large amounts of data, from miles driven to drive-time anomalies. SQL Nanodegree program SQL databases This data is stored in the database and analyzed on a large scale, which helps Mal and her team make informed decisions. “Being able to query that large database and join datasets to be able to tell that story is very critical to my role,” says Mal. Without the ability to use SQL for reading and analyzing the data, Mal would miss out on important insights that are easy to overlook when just seeing data stored in a database. Who Uses SQL? Many of the different jobs across departments at tech companies use SQL. According to Mal, “[It is] critical for every single person on my team to know SQL.” She reports using it with other PMs, engineers, DevOps, and even the infrastructure team. According to Zippia, the top jobs that use SQL include: Business Analyst Software Engineer Database Administrator QA Tester Project/Product Manager Over 60% of developers use SQL databases for managing data, making the language a good place to start for people trying to add data analytics to their resume. surveyed Learning SQL Having SQL skills can lift you into a better, more strategic role in your company.

Then, you will use DDL to create a new, normalized database and DML queries to migrate the data from the old database to your new one. Learning Outcomes Ziad Saab, an instructor for Udacity’s SQL Nanodegree program and a software developer at DecodeMTL, said it best: “In terms of career, if you are looking at becoming a data analyst, or if you are a developer who’s just been through boot camp and is looking to move into the world of back-end or full stack development, you are going to get a lot out of this course.” front-end Beyond the technical know-how of working with SQL, you will also learn how to reason about data. Through real-world datasets and challenging final projects, you will understand how to look at data in an entirely new way. to get started!
