In this course, you will get information on unlocking legacy system architecture.

What will you learn in this course?

• Introduces a set of episodes around the term Spaghetti code, and how many systems are not understood by today's developers because they do not understand the principles of the underlying systems
• Discusses the basic program structure that is at the core of tabulating system principles, much of which undergirds many systems described as Spaghetti code
• Outlines how the posting processes sit at the core of tabulating systems, rolling forward each day into the next day
• Drills down on program structure of tabulating systems, outlining where the complexity starts to show up in these otherwise simply little programs
• Data discovery in a tabulating system environment looks different than in many other types of settings
• Metadata is often used to understand systems environments. You will learn what some of the metadata looks like in a tabulating system environment
