A data warehouse (DW) is a central data repository. It collects data from operational systems and various other sources. This resource supports powerful analytics applications. These applications help drive crucial business decisions. Data warehousing is key to any robust data management strategy.
What is a Data Warehouse?
DWs process and organize stored data for analysis. Business analysts, executives, and data scientists use this information. Typically, a DW is a relational or columnar database. It lives in the cloud or an on-premises data center. Data comes from online transaction processing (OLTP) applications. It also comes from internal and external sources. The data is consolidated for business intelligence (BI). BI uses include querying, decision support, and reporting. Users access this data through BI software and analytics tools.
Understanding DW Architecture
A fundamental DW architecture contains three tiers. It includes a data integration layer. Tools in this layer extract and combine data from operational systems. A staging area cleanses and transforms this data. It organizes the data before loading it into the warehouse. Data quality software handles tasks at this staging level. An enterprise data warehouse (EDW) stores analytical data for all operations. Alternatively, large companies may use separate data warehouses. DWs also connect to data marts. Data marts are smaller systems. They hold data subsets for specific users or departments.
Design Approaches: Inmon vs. Kimball
Organizations follow two main implementation paths. These are the top-down and bottom-up methods.
1. The Top-Down Method (Inmon)
William H. Inmon pioneered this approach. It calls for building the EDW first. You then use this centralized data to set up data marts. Data is validated in a staging area. It integrates into a normalized data model. This prepares it for planned BI and analytics uses.
2. The Bottom-Up Method (Kimball)
Ralph Kimball developed this alternative. This approach creates dimensional data marts first. Data models use a star schema design. Fact tables connect to one or more dimensional tables. Data marts can populate an EDW or integrate with each other. A hybrid approach combines aspects of both methods. Federated data warehouses integrate separate analytical systems.
Benefits of Data Warehousing
DWs offer business and IT advantages. They enable faster, more efficient data access. They have the compute resources for running complicated queries. Businesses derive quick insights and value from their data. Companies use DWs for enterprise reporting and strategic decision-making.
