Key Concepts and Terminologies

Data engineering involves a wide array of concepts and terminologies that are essential for managing and processing data effectively. Here are some of the key concepts and terminologies used in data engineering:

1. Data Pipeline

A data pipeline is a set of data processing steps configured to automate the flow of data from one stage to another. It is used for data collection, transformation, and loading into analysis systems.

2. ETL (Extract, Transform, Load)

A type of data pipeline specifically designed to extract data from various sources, transform it into a structured format, and load it into a data storage system, typically a data warehouse.

3. Data Lake

A data lake is a storage repository that retains a large volume of raw data in its original format until required. Unlike a data warehouse that maintains data in a structured format, data lakes are engineered to accommodate unstructured, semi-structured, and structured data.

4. Data Warehouse

A data warehouse is a central repository for current and historical data, optimized for query and analysis. It is a crucial component of business intelligence, providing a unified reporting and data analytics system.
