Structured Query Language (SQL) is the primary language used for accessing and managing data in a relational database system. Analysts, project managers, and other professionals want to make informed decisions using large datasets, but without a working knowledge of SQL, they often have to request that IT staff perform these data retrievals.
Expert George Mount walks you through using SQL to query a database to extract the information you need for your analyses. No prior experience in programming or databases is required. As an Excel user, you already know more about these topics than you realize. Over three informative hours, you’ll discover how the foundations of SQL relate to everyday Excel tasks, empowering you to better explore and analyze your own databases.
What you’ll learn and how you can apply it
By the end of this course, you’ll understand:
The basics of relational databases and SQL’s role
The foundational commands used for reading data from one or more tables in a database
Concepts such as schemas, primary keys, and foreign keys (i.e., what makes relational databases “relational”)
And you’ll be able to:
Use SQL to query a database to extract useful information
Explore basic SQL commands and functions
Extract data and work with queries to pull the data you need for your analysis
You’re an analyst, project manager, or other professional working with data.
