Data Warehouse

A centralized repository that stores large volumes of structured data from multiple sources, optimized for analysis, reporting, and business intelligence applications.

What is a Data Warehouse?

A data warehouse is a large, centralized database specifically designed for query and analysis rather than transaction processing. It collects and consolidates data from various operational systems, transforms it into a consistent format, and stores it in a way that supports complex analytical queries and reporting.

Unlike operational databases that handle day-to-day transactions, data warehouses are optimized for read-heavy workloads and analytical processing. They serve as the foundation for business intelligence, data mining, and advanced analytics initiatives across organizations.

Key Characteristics of Data Warehouses

Subject-Oriented

Organized around key business subjects like customers, products, or sales rather than applications.

Integrated

Combines data from multiple sources into a consistent, unified format with standardized naming and coding.

Time-Variant

Maintains historical data over time, enabling trend analysis and historical reporting.

Non-Volatile

Data is stable and doesn't change once entered, ensuring consistent analytical results.

Optimized for Analysis

Designed for complex queries, aggregations, and analytical processing rather than transactions.

High Data Quality

Implements data cleansing, validation, and quality assurance processes during ETL operations.

Data Warehouse Architecture

1

Data Sources

Operational systems, databases, files, APIs, and external data feeds that provide raw data.

2

ETL Layer

Extract, Transform, Load processes that clean, standardize, and integrate data from various sources.

3

Storage Layer

The central repository where processed data is stored, often using dimensional modeling or data vault approaches.

4

Access Layer

Tools and interfaces that enable users to query, analyze, and report on warehouse data.
