> This writer worked for one publishing company that used Notes extensively, and I found it to be incredibly useful in its day. It provided not just your email, but an internal telephone directory, contact database, booking system for time off, company handbook, and more, all accessible via a single application and a single set of credentials, long before single sign-on became a thing

Sounds like Workday but less complicated (because Workday also does payroll, and payroll sucks)
