MySQL Querying Fundamentals Course Outline
Organizations use large SQL databases to store information about clients, products, or sales. However, that data is locked into those databases until it is accessed by a business intelligence tool such as Power BI, Tableau, or Crystal Reports. Analysts and Data Scientists can use SQL to select the data they need for additional analysis and reporting. This class, MySQL Querying: Fundamentals, provides an overview of the SQL statements that can be used to access that data. This course covers MySQL 8.0.
• Connect to the MySQL Server database and execute a simple query.
• Include a search condition in a simple query.
• Use various functions to perform calculations on data.
• Organize the data obtained from a query before it is displayed on-screen.
• Retrieve data from multiple tables.
This course is intended for individuals with basic computer skills, familiar with concepts related to database structure and terminology, and who want to use SQL to query databases.
Some familiarity with database terminology and structure is helpful.
