Introductory SQL with optional Big Data modules
Strengths
Core Querying Fundamentals
Instruction covers essential database operations including creating tables, modifying data through CRUD commands, and performing aggregations like count, sum, and average.
Interview-Style Practice
The curriculum includes specific sections dedicated to interview question-style exercises to aid practical application.
Limitations
Limited Advanced Coverage
The curriculum lacks coverage of advanced topics such as CTEs, self joins, or pivoting. One signal from a review dated September 2024 suggests these are missing; however, because this predates the displayed update date, it is uncertain if the content has since been addressed.
Superficial Big Data Content
The optional Spark and AWS EC2 module is described as incomplete or lacking necessary technical context. A signal from October 2022 notes this deficiency, but the update label does not prove a correction has occurred.
Instructional Pacing and Setup
Some learners encountered difficulties with Windows-specific installation instructions and noted instances where the instructor moved through concepts too quickly. A signal from December 2022 highlights these issues, though the update label does not guarantee a resolution.
Best suited to
- Beginners seeking introductory SQL skills
- Learners preparing for entry-level data interviews
Less suited to
- Users requiring advanced query techniques like CTEs
- Those seeking deep technical context for Spark and Big Data
