# Unified Schema Introduction

## Overview

Currently there are seven (7) Unified Schemas (normalized data models) deployed:

* [Unified Retail Sales (URS)](/core-concepts/data-models/unified-schemas/unified-retail-sales-urs.md): consolidates your brand’s own **retail POS, wholesale shipments, and inventory data** into a unified structure, enabling consistent analysis of sell-in, sell-out, and on-hand stock across retailers and channels
* [Unified Retail Market Sales (URMS)](/core-concepts/data-models/unified-schemas/unified-retail-market-schema-urms.md): standardizes **syndicated retail market data** from sources like NielsenIQ, Circana/IRI, and SPINS, allowing you to analyze **category performance, market share, distribution, and velocity** in the context of competitors and the total marke
* [Unified Order Schema (UOS)](/core-concepts/data-models/unified-schemas/unified-order-schema-uos.md): normalizes **order and transaction data across all sales channels with order-level details**—including eCommerce, marketplaces and POS/B2B —into a consistent structure that supports multi-item, multi-shipment, and multi-recipient orders.
* [Unified Marketing Schema (UMS)](/core-concepts/data-models/unified-schemas/unified-marketing-schema-ums.md): consolidates **paid marketing performance data** from platforms like Facebook, Google, TikTok, and Amazon Ads into a unified view of spend, clicks, impressions, and attributed outcomes.
* [Unified Notification Schema (UNS)](/core-concepts/data-models/unified-schemas/unified-notification-schema-uns.md): centralizes **customer messaging data** from email, SMS, push, and in-app platforms, enabling cross-channel engagement and campaign performance analysis.
* [Unified Traffic Schema (UTS)](/core-concepts/data-models/unified-schemas/unified-traffic-schema-uts.md): integrates **digital and retail traffic data** from sources like Google Analytics, Amazon, and in-store counters, providing a unified view of sessions, pageviews, and conversion across all channels.
* [United Subscription (USS)](/core-concepts/data-models/unified-schemas/unified-subscription-schema-uss.md#overview): unifies **subscription program data**—covering subscribers, active subscriptions, churn, shipments, and repurchase behavior—so brands can track retention, forecast recurring revenue, and optimize subscription health over time.<br>

#### Deprecated

* [Unified Wholesale Schema (UWS)](/core-concepts/data-models/unified-schemas/legacy-schemas/unified-wholesale-schema-uws.md): Prior to Daasity's acquisition of Red Fox Analytics in 2025, Daasity used the UWS to normalize sell-in and sell-out data for Wholesale data. Since late 2025, the UWS has been phased out, and replaced with the [Unified Retail Sales (URS)](/core-concepts/data-models/unified-schemas/unified-retail-sales-urs.md) schema, but remains active for some customers with legacy custom projects involving the UWS.
