Key Concepts

Subject-Oriented

This concept refers to the organization of data around key subjects of the business, such as customers, products, or sales. Rather than focusing on the day-to-day operations of an organization, data in a data warehouse is structured to support analysis and decision making about these major areas, ensuring that the information is relevant to the key business processes and decision support activities.

Integrated

Integration entails the consolidation of data coming from various disparate sources, each potentially using different naming conventions, formats, and measurement units. In a data warehouse, this data is cleansed, transformed, and standardized to ensure consistency and coherence, making it possible to perform accurate and reliable analysis across the entire organization.

Time-Variant

Time-variant data means that a data warehouse maintains a historical record of information over time. This characteristic allows for the analysis of trends, patterns, and changes within the business by storing timestamps or period-specific snapshots of data, thereby supporting longitudinal studies, forecasting, and temporal analysis.

Non-Volatile

Non-volatility in a data warehouse indicates that once data is entered into the system, it is not frequently updated or deleted. Instead, new data is appended over time without interference with the historical records. This attribute ensures data stability and integrity, enabling consistent trend analysis and reporting based on a stable repository of information.
