datavoorraad

Datavoorraad is a Dutch term that translates to "data warehouse" in English. It refers to a system used for reporting and data analysis, and is considered a core component of business intelligence. A datavoorraad is a central repository of integrated data from one or more disparate sources. These sources can include transactional databases, operational systems, and external data feeds. The primary purpose of a datavoorraad is to support decision-making by providing a consolidated and structured view of an organization's data.

The data within a datavoorraad is typically organized to facilitate querying and analysis, rather than to support day-to-day transactions. This means the data is often transformed, cleansed, and structured into a format optimized for reporting and business intelligence tools. Common data models used in datavoorraden include star schemas and snowflake schemas.

Key characteristics of a datavoorraad include its subject-oriented nature, meaning data is organized around key business subjects like customers, products, or sales. It is also integrated, bringing together data from various sources into a consistent format. Datavoorraden are non-volatile, meaning data is not typically updated or deleted once it's in the warehouse, but rather added to. Finally, they are time-variant, storing historical data to enable trend analysis and historical reporting. Implementing a datavoorraad can be a significant undertaking, requiring careful planning and execution.
