It was a pretty good course overall. Some parts moved a little fast for me, but the examples were generally helpful. Worth the time investment.

About this course
Mainframe systems continue to power the world's most critical financial and enterprise transactions. To work with these robust systems, understanding how to connect COBOL programs to DB2 databases is an essential industry skill.
This course guides you through the process of writing COBOL programs that seamlessly interact with DB2 databases. You will transition from understanding basic database concepts to writing structured SQL queries directly within your mainframe code, preparing you to handle real-world enterprise data challenges.
What you'll learn:
- Understand foundational mainframe database concepts, table structures, and relational database terminology.
- Write and execute DDL commands to define tables and DML commands to manipulate database records.
- Embed SQL statements inside COBOL programs using host variables and precompilers.
- Manage multi-row query results using DB2 cursors for efficient data processing.
- Implement robust error handling by interpreting SQLCODE and SQLSTATE values.
- Apply modern best practices for query performance and efficient mainframe data access.
The course begins with foundational database concepts and DB2 terminology before moving into practical SQL syntax. You will then explore how to embed these queries into COBOL structures, handle multi-row processing, and debug common database errors.
This course is designed for aspiring mainframe developers, system analysts, and programming beginners who have a basic understanding of COBOL and want to learn database integration. No prior DB2 experience is required.

Found it useful for a refresher. Not sure it would be the best starting point for a complete beginner, tbh.
It's a good course if you have some prior knowledge. For absolute beginners, some concepts might be a bit challenging. The structure is logical, though.
It provides a good starting point. My main issue was with the clarity of a couple of the later modules.
Hmm, I'm not sure this is for absolute beginners. It assumes a bit of prior knowledge that wasn't explicitly taught. Some examples were confusing.
Thoroughly enjoyed this course. The way the information was presented was excellent, and the practical applications were highlighted effectively. Great job!
It's a solid course. The structure is logical and most of the examples were helpful. Could use a few more real-world scenarios though.
Good introduction to the topic. The structure was logical, and most of the examples were relevant, though I wished for more depth in certain areas.
