Beginner's guide to mainframe ims-db

According to learners, this course serves as a solid introduction to Mainframe IMS-DB for absolute beginners. Students appreciate the clear explanations of fundamental concepts like DBD, PSB, PCB, and SSA. The course provides practical examples integrated with COBOL programming, which many find highly relevant for real-world applications in mainframe environments. While it is well-suited for those new to the topic and covers necessary basics, some learners feel it lacks sufficient hands-on exercises or a practical environment to reinforce the theoretical concepts learned. Minor issues like audio/video quality could be improved, but overall, it delivers on its promise as a beginner-level training.
