Enterprise applications are made up of so many pieces that even if each piece is very simple, the end-to-end flow can quickly become complicated. Then there are additional levels on top of the execution flow, like the data model — what data is being used, where is it updated, where is it changed, etc. Enterprise applications aren’t for the faint of heart. Luckily, you can apply technology to these complicated solutions to make them easier for developers to understand, and thus maintain.
This tutorial will introduce you to this type of technology using a sample COBOL application. Using a virtual lab environment, you will use IBM Application Discovery and Delivery Intelligence to generate diagrams of the sample application. You will even be able to interact with these diagrams after they are generated so you can see just the right amount of detail to quickly understand how the pieces of the sample
