Differences among a BMS, DCIM and a CPMS

Do you know the differences among a BMS, DCIM, and a CPMS? Though there are similarities, the differences are important to consulting engineers, contractors, building owners and facility executives at data centers. Though each is designed to improve efficiency and operational reliability, lower costs, and enhance worker safety, one technology may be a lot better suited for a given application than another. The first two technologies (Building Management System and Data Center Infrastructure Management) aim to monitor and control an entire facility or campus, including critical power, while the third (Critical Power Management System) is dedicated to controlling only critical power generation and distribution systems. What are you using at your data center to achieve your goals?
