To modernize your application, you first need to understand database operations and transaction processes inside the application. Tackle-DiVA helps you do that easily with automatic data-centric code analysis. It extracts database/transaction dependencies and suggests refactored transaction processes. Learn how this new tool contributed by IBM Research works and how you can use it in your next modernization project at this meetup. Presenter: Yasu Katsuno, Ph.D - Research Staff Member, IBM Research - Tokyo
