Ellucian Ethos provides a standard data model, REST APIs and change notifications for Banner and other systems. What it is and why it matters for integrations.

**Short answer:** Ellucian Ethos is Ellucian's integration platform. It defines a common data model for higher-education data, exposes Banner and other Ellucian systems through REST APIs, and publishes change notifications so connected applications can react when data changes. Integrations authenticate with application-specific API keys instead of direct database credentials.

## Overview

Ethos is the **supported front door** to Banner data for other systems.

## The core ideas

| Concept | What it means |
|---|---|
| Ethos Data Model | Standard resource definitions such as persons, sections and student registrations |
| Ethos APIs | REST endpoints to read and write those resources |
| Change notifications | Events published when data changes |
| API keys | Each connected application gets its own credentials and permissions |
| GUIDs | Stable external identifiers instead of internal keys such as PIDM |

## Why it matters

- **Upgrade safety**: APIs are versioned, unlike direct table access.
- **Security**: scoped API keys instead of shared database accounts.
- **Speed**: near real-time updates through notifications.
- **SaaS readiness**: a requirement for many cloud migrations.

## Frequently asked questions

### Do I still need direct database integrations with Ethos?

Ethos aims to replace most direct database integrations with supported APIs, which survive upgrades better and are required for many SaaS scenarios.

### What is a change notification?

A message Ethos publishes when a record changes, so subscribing applications receive updates instead of polling Banner.
