You've told us what it isn't, why not tell us what it is. "manages the whole effort" is pretty meaningless, a time sheet application can make that claim.
Imagine building software to handle all the HR needs, IT needs, accounting needs, CRM needs, etc, for a 600,000 person company. Assume that this is also going to be the mother of legacy-tech-debt projects, too. Then, add on the feature of ingesting and actually processing and storing the raw census data, too. Then imagine that it's not a company, but a government agency doing that.
