POWERUp 2019

Nobody likes to tell the bigwigs that changing the software to accommodate a change in business requirements is impractical or impossible. Whereas we need to say yes, we often say no because we lack time and resources to modify the software systems we support. Abstraction, the hiding of unnecessary detail, makes software more flexible and open to change, and makes programmers more productive. In this session, Ted Holt shows how to use such common techniques as SQL views, logical files, and service programs to build software that can respond to changing business requirements. Aren’t you tired of saying no?

Learning Objectives:


1. Learn the pitfalls and shortcomings of traditional application change techniques.
2. Learn the true purpose of logical files and SQL views.
3. Learn how changing an application over time through small projects, rather than large projects, can lead to success.
