Advanced Database Queries

This course will soon be retired. Last day to enroll is 12/31/2022 at 00:00 UTC.

This is the 2nd course in the introductory, undergraduate-level offering that makes up the larger Introduction to Databases MicroBachelors Program. We recommend taking them in order, unless you have a background in these areas already and feel comfortable skipping ahead.

1. Introduction to Databases
2. Advanced Database Queries
3. Advanced Database Administration

These topics build upon the learnings that are taught in the introductory-level Computer Science Fundamentals MicroBachelors program, offered by the same instructor.

This course is a continuation of the basic concepts, organization, and implementation models taught in the Introduction to Databases course, with an emphasis on the relational model. Among the topics covered are the development of advanced queries that utilize aggregation, subqueries and built-in functions. Aggregation queries are used to pull back summary data to help understand the detailed instances in the database. Subqueries help to break large into smaller testable component parts. Functions are used to format and perform calculations on the data returned in the query. Database development and administration skills are required in most Information Technology, Software Engineering, Cybersecurity, and Computer Science jobs. The course utilizes the open-source relational database MySQL. MySQL and it's open-source fork MariaDB are used in millions of web apps to persist the application data and provide query processing. Applied labs expand on the lectures to provide students with hands-on experience with a relational database management system (DBMS) and structured query language (SQL).

If you successfully complete all the courses within the program, with a passing grade of 70% or better via the verified (paid) track, you’ll not only receive a certificate highlighting your achievement, but also have the option to collect real college credit (included in the price!) that you can count towards a pursuit of a bachelor’s degree.
