Brief Introduction
Learn the fundamentals of interacting with relational database management systems, including issuing queries that return results sets and modify data.
Description
This is the 1st 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.
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 an introduction to the basic concepts, organization, and implementation models of databases, with an emphasis on the relational model. Among the topics covered are the development of simple queries that retrieve and mutate the data in a database. Data Manipulation Language (DML) is a subset of SQL that is used by database developers to create, maintain, and query facts in the database. Students gain a thorough understanding of the DML syntax and the options available when retrieving facts back from the database. 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. The applied SQL labs expand on the classroom lectures to provide students with hands-on experience with a relational database management system (RDBMS) 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.
