# Sales Business Context: Entities, Events, and Evidence

> The core business entities, relationships, events, and evidence types that define the Sales domain projection in Spine Fabric.

The Sales business context is the semantic layer Spine Fabric uses to assemble meaning from raw CRM, email, and conversation data. Understanding these entities and relationships helps you interpret why Twin surfaces certain alerts and how projections stay consistent across views.

## Entities

| Entity | Definition | Key Attributes |
| - | - | - |
| Lead | An unqualified prospect | Source, score, status, owner |
| Account | A target organization | Industry, size, territory, tier |
| Opportunity | A qualified deal | Stage, amount, close date, probability |
| Contact | An individual stakeholder | Role, influence, engagement score |
| Activity | A logged interaction | Type, date, outcome, related records |
| Deal | The active sales engagement | Strategy, competitors, next steps |
| Quote | A pricing proposal | Products, discounts, expiration |
| Forecast | Revenue projection rollup | Category, period, commit amount |

## Relationships

* Account has many Contacts.
* Account has many Opportunities.
