Legacy system assessment is a crucial task to identify the programs involved in an application. Due to unavailability of modern tools to quickly assess the older system(s), it is important to have a clear understanding and statistics of the code before performing any operation. As a project team - both in-house and vendor - to perform any form of estimation, do a knowledge transfer, understand business logic / rules or simply understand the system scope, it is crucial to assess it. floU delivers all the required elements for quick code assessment in form of a simple-to-use tool. Not only does the output provide details listed below, but also provides it in usable HTML format. You can use it to find program details like lines of code (LoC), complexity, connectivity, business rules, annotations and tags, data elements / files used and a diagram of the overall system. You can use this information to provide automation to understand the existing application and forward engineer it to newer modern platforms. The tool provides various artifacts which include: Quick glance dashboard Program statistics - LoC and Complexity Screen details - number of screen elements Job details - its composition Who uses what? Programs, Screens, Jobs and Data Data Dictionary w/CRUD and where it is used Overall system connectivity diagram with all the elements Identify business logic and annotate business rules
