It includes the data warehouse database.<\/li>\n<li><strong>Front-End Layer:<\/strong> The front-end layer provides tools and interfaces for querying and reporting on the data.<\/li>\n<\/ul>\n<\/li>\n<li>This architecture enhances scalability, maintainability, and security.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Hub-and-Spoke (Hub-and-Spoke with Satellite) Architecture:<\/strong>\n<ul>\n<li>The hub-and-spoke architecture, also known as the hub-and-spoke with satellite architecture, involves a central hub and multiple spokes.<\/li>\n<li>The central hub serves as the primary data repository, while the spokes represent data marts or department-specific warehouses.<\/li>\n<li>Data from the hub is selectively replicated to the spokes as needed.<\/li>\n<li>This architecture allows for both centralized data control and decentralized department-specific reporting.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Data Warehouse Bus Architecture:<\/strong>\n<ul>\n<li>The data warehouse bus architecture extends the three-tier architecture by incorporating a bus structure connecting data marts.<\/li>\n<li>Each data mart represents a specific subject area, and they share common dimensions and facts from the central data warehouse.<\/li>\n<li>This architecture supports both enterprise-wide reporting and departmental analytics.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Federated (Virtual) Architecture:<\/strong>\n<ul>\n<li>A federated EDW architecture integrates data from various source systems on an as-needed basis, without physically centralizing the data.<\/li>\n<li>It provides a unified view of data across distributed sources, enabling real-time access to data without data duplication.<\/li>\n<li>Federated architectures are suitable when centralization is not feasible or necessary.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Data Lake Integration:<\/strong>\n<ul>\n<li>Many organizations incorporate a data lake into their data warehousing architecture.<\/li>\n<li>Data lakes store raw and unprocessed data from a variety of sources, which can then be ingested, processed, and integrated into the data warehouse as needed.<\/li>\n<li>This approach allows for flexibility in handling diverse data types and supports big data and advanced analytics use cases.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">The choice of EDW architecture depends on factors such as the organization&#8217;s data management strategy, scalability requirements, data integration complexity, and the need for departmental or centralized analytics.
