Back to Glossary
Data pipelines are automated workflows that move data from source systems to destination systems, usually transforming it along the way. They are the backbone of modern analytics, ensuring that data flows reliably from applications into data warehouses, lakes, or analytical tools.
A typical data pipeline includes:
Data ingestion (from APIs, databases, files, or event streams)
Transformation (cleaning, enriching, joining, or aggregating data)
Loading (storing data in warehouses or analytics systems)
Scheduling and orchestration
Monitoring and error handling
In BI and analytics, data pipelines power dashboards, reports, machine learning models, and operational alerts. Without pipelines, analytics becomes manual, slow, and error-prone.
Pipelines can be:
Batch pipelines (run on a schedule)
Streaming pipelines (process data in real time)
Hybrid pipelines (batch + streaming)
Tools commonly used include Airflow, dbt, Fivetran, Airbyte, Kafka, Spark, and cloud-native services.
From a business perspective, reliable data pipelines ensure data freshness and accuracy. Broken pipelines lead to outdated dashboards, missed insights, and loss of trust in analytics.
Technically, pipelines must handle:
Schema changes
Data volume spikes
Partial failures
Retries and backfills
Data validation
Well-designed pipelines are modular, observable, and version-controlled. Modern analytics teams treat pipelines like production software, using testing and monitoring to ensure reliability.
Data pipelines turn raw data into analytics-ready data, making them essential infrastructure for BI systems.
