Reviews summary

Cics transaction server: high-level overview

According to learners, this course offers a largely positive and clear, concise high-level overview of CICS Transaction Server, proving invaluable for understanding its role in enterprise computing. Many found the instructor's explanations illuminating and accessible, especially for those new to mainframes, project managers, or system architects. However, some students note that while the course successfully delivers the 'big picture', it lacks the practical, hands-on application development depth they sought, feeling more like a lecture series than a skill-building course. It is generally considered a strong foundational piece but not suited for those seeking nitty-gritty coding details or extensive coverage on modernizing legacy applications.

Some aspects felt slightly dated in terms of presentation.

"My only minor critique is that some parts felt a little dated in terms of presentation, but the core information is still highly relevant."

"I found the pace a bit slow at times, and some of the explanations were a bit too abstract."

Touches on modernization, but some expected more detail.

"I was hoping for a bit more on modernizing legacy applications, as mentioned in the description. It touched upon it, but only briefly."

Valuable for managers, architects, and new mainframe users.

"This course is essential for project managers or system architects who need to grasp CICS without getting bogged down in coding specifics."

"Good course for non-developers or managers who need to understand CICS."

"As someone who inherited legacy CICS applications, this course was invaluable. It helped me connect the dots and understand the underlying principles quickly."

Delivers well on its promise of a foundational overview.

"The course delivers on its promise of a 'big picture' view, laying a solid foundation."

"It's truly a big picture perspective... It explains the 'why' and 'what' very well."

"The focus on the 'big picture' truly helps you grasp the context without getting lost in details. It's a foundational piece for anyone dealing with mainframes."

Provides an easily digestible, high-level understanding.

"This course provided a really good high-level overview of CICS. The instructor was clear and concise, making complex topics digestible."

"Excellent course for understanding where CICS fits into the larger enterprise ecosystem. The explanations of transaction services... were particularly illuminating."

"The instructor made the subject matter very accessible. I'm a seasoned IT professional, but CICS was always a black box for me. This course demystified it completely."

Not suitable for those seeking hands-on coding or deep technical skills.

"I came in hoping for more practical examples or scenarios related to CICS application development... you might find it lacking in depth."

"If you're a developer or want to get into the nitty-gritty of CICS programming, this isn't for you."

"It feels more like a lecture series than a hands-on skill-building course. I would have preferred more concrete examples."

"I agree with other comments that if you're looking for deep technical details or extensive hands-on coding, this isn't the right fit."
