In this 80-hour hands-on course, trainees learn SQL (Structured Query Language), a mainstream language used to create, manage, and query RDBMSs (Relational Database Management Systems). At the end of this course, trainees are prepared to work with SQL database servers.
You must successfully complete a two-hour self-assessment to gain acceptance to this course. A background in coding is helpful but not required.
Trainees will be able to:
- Use units of data size to determine data storage requirements.
- Explain the basic principles of relational (SQL) and non-relational (No-SQL) databases.

Course Structure and Length
The course is self-paced, and trainees practice each skill or concept as they go. Automatic feedback is built into the course for both practices and quizzes.
The course is divided into four Units, and each Unit is composed of five Sections. Each Section consists of 7 instructional/practice levels, a quiz, and a master (proficiency) level. Trainees can return to any level or quiz for review.
While learning skills in the SQL Fundamentals course, trainees can practice queries and create portfolio artifacts with NCLab’s SQL apps. They can use a project idea from NCLab or create their own. NCLab provides several practice databases that can be queried with the SQL app.
Trainees will need approximately 80 hours to complete the course. Since the course is self-paced, the amount of time required to complete the course will vary from trainee to trainee. Trainees are responsible for learning both the tutorial content and the skills acquired through practice.
