# Data Model

# Technical Support: Data Model

This page describes the example domain model used in the Technical Support demo repository. Use it as inspiration for how to think about entities, relationships, and searchable fields.

# Example entities

• Device: product/device names
• Part: parts associated with devices, with manufacturer metadata
• Manufacturer: normalized manufacturer entity (useful for navigation and filtering)
• SupportCase: a case/ticket with summary, content, status, and timestamp
• SupportCaseMessage: parsed messages extracted from case conversations
• Status: normalized status entity (useful for shared facets)

# Example relationships

• Device -> HasPart -> Part
• Part -> HasManufacturer -> Manufacturer
• SupportCase -> ForDevice -> Device
• SupportCase -> HasStatus -> Status
• SupportCase -> HasMessage -> SupportCaseMessage

# Why this model works well

• It supports entity-centric navigation (device/manufacturer pages).
• It supports graph-constrained search (search within a manufacturer/device).
• It separates attributes (properties) from entities (nodes) where navigation/faceting matters.
