Now Platform Architecture

Perché: Lets you judge which request the platform can meet natively and which would work against its multi-tenant design, before promising a delivery date.

Instances & Nodes

Perché: Lets you plan a change through dev, test and production, and account for a clone that will overwrite sub-production data before UAT.

Tables & the Data Dictionary

Perché: Lets you change a dictionary attribute knowing it applies platform-wide, and choose the right table when a team asks for a new kind of record.

Fields & Field Types

Perché: Lets you pick the field type that keeps reports clean, such as a reference instead of a string for a department, and avoid data you cannot filter later.

Users, Groups & Roles

Perché: Lets you design groups and roles for a new team, using inheritance, so access stays manageable when people join, move or leave.

Access Control Rules (ACLs)

Perché: Lets you restrict who can read or edit a sensitive field, such as HR cases, with an ACL, and tell why a user still cannot see a record.

Flow Designer — Flows & Triggers

Perché: Lets you automate a routine, such as notifying an owner when a record is updated, with the right trigger, and activate it without creating a loop.

Flow Actions & Subflows

Perché: Lets you move a repeated sequence, such as approval plus notification, into a subflow so you fix it once instead of in five flows.

Incident Management

Perché: Lets you tune categories, priorities and assignment rules so incidents reach the right group, and support the process during a major incident.

Problem & Change Management

Perché: Lets you configure the path of a normal, standard or emergency change, including CAB and conflict detection, and link recurring incidents to a problem record.

Reports & Report Types

Perché: Lets you build a report for a weekly service review, choose the chart that answers the question, and schedule it to the group that needs it.

Dashboards & Performance Analytics Overview

Perché: Lets you assemble a dashboard for a team lead and explain when trend analysis over time needs Performance Analytics instead of a standard report.
