In Business Intelligence and Data Warehousing architecture, the commonly recognized types of Data Warehouses are:
-
🏢 Enterprise Data Warehouse (EDW) – Provides integration of data from many sources into a standard format
📌 A centralized, organization-wide repository that integrates data from multiple sources for strategic decision-making. -
🧩 Data Marts (DMs) – Provides a fairly recent form of customer information file and is used as an interim staging area
📌 Smaller, subject-oriented subsets of a data warehouse designed for specific departments (e.g., marketing, finance). -
🛠️ Operational Data Store (ODS) – Provides a fairly recent form of customer information file and is used as an interim staging area
📌 A database designed for integrating data from multiple sources for operational reporting and short-term decision-making. Though not a full data warehouse, it is often considered part of the data warehousing environment.
