Also known as: Event Data
Recorded business events or operations, such as orders and payments, with measures and references to master and structure data.
DESCRIPTION
Transaction Activity Data captures the actual occurrences of business processes: orders, shipments, invoices, clicks, and sensor events. It includes timestamps, quantities, monetary amounts, and foreign keys to master and structure data. It is append-heavy, immutable, and optimized for analysis in fact tables or event logs. Streaming and batch pipelines ingest, validate, and model it for BI and ML. Governance ensures privacy, retention, and reconciliation with ledgers.
ALTERNATIVE DEFINITIONS
Wikipedia
Transactional data is information that documents an exchange, agreement, or transfer that occurs between organizations and individuals.
Stresses documenting exchanges and transfers, the core of activity data.
Wikipedia
A fact table stores quantitative data for analysis and is often denormalized.
Connects transactional measures to dimensional modeling constructs.

TOP QUESTIONS
What types of data are Transaction Activity Data?
Orders, invoices, payments, shipments, clickstreams, and sensor events are common transaction activities.
Category: Definition
How is Transaction Activity Data modeled?
As fact tables in dimensional models or as append-only event logs in streaming architectures.
Category: Example
How does it relate to Master Data?
Transactions reference master entities via foreign keys, enabling consistent analysis and attribution.
Category: Integration
What are common ingestion patterns?
CDC from OLTP, event streaming (Kafka), batch file ingest, and API capture.
Category: Requirements
What quality checks are essential?
Schema validation, referential integrity, deduplication, and reconciliation with source ledgers.
Category: Requirements
How long should Transaction Activity Data be retained?
Retention follows legal, financial, and analytical requirements, often tiered storage with lifecycle policies.
Category: Opinion
What risks exist with transaction data?
Privacy exposure, reconciliation mismatches, and performance issues at scale if poorly partitioned.
Category: Risks
Why is time important in Transaction Activity Data?
Timestamps enable time-series analysis, SLA tracking, and Slowly Changing Dimensions alignment.
Category: Relevancy
How does streaming change Transaction Activity Data use?
Streaming supports near-real-time analytics, alerts, and operational decisioning on fresh events.
