Each of these buzzwords maps to real tables and modules you can open right now in a PDI:

Term	Where to find it	Key table
ITSM	Incident > All, Change > All	`incident`, `change_request`
CMDB	Configuration > Servers, All CIs	`cmdb_ci`
CSDM	CMDB Workspace > Service Mapping	`cmdb_ci_service`, `cmdb_ci_business_app`
SecOps	Security Operations > Vulnerabilities	`sn_vul_vulnerable_item`
App Engine	App Engine Studio	`sys_app`
Now Assist	Now Assist Admin Console	Configured per skill in the Admin console (no single table)

// Quick check: how many incidents exist in your instance?
var ga = new GlideAggregate('incident');
ga.addAggregate('COUNT');
ga.query();
if (ga.next()) {
    gs.info('Total incidents: ' + ga.getAggregate('COUNT'));
}
// Try this in a Background Script on your PDI.
