The Plain-English Guide to Data Warehouses + Examples
A hybrid (also called ensemble) data warehouse database is kept on third normal form to eliminate data redundancy. A normal relational database, however, is not efficient for business intelligence reports where dimensional modelling is prevalent. Small data marts can shop for data from the consolidated warehouse and use the filtered, specific data for the fact tables and dimensions required. The data warehouse provides a single source of information from which the data marts can read, providing a wide range of business information. The hybrid architecture allows a data warehouse to be replaced with a master data management repository where operational (not static) information could reside. Typically, a data warehouse is a relational database or columnar database housed on a computer system in an on-premises data center or, increasingly, the cloud.
It specially designed for a particular line of business, such as sales, finance, sales or finance. In an independent data mart, data can collect directly from sources. The data is processed, transformed, and ingested so that users can access the processed data in the Data Warehouse through Business Intelligence tools, SQL clients, and spreadsheets. A data warehouse merges information coming from different sources into one comprehensive database.
Data lakes also use a flat architecture where data is hierarchical or non-relational when stored. Using folders and subfolders makes up the hierarchical organization of files. Uncovering the differences between a data lake and a data warehouse starts by digging into the details of each. Sometimes, having all your data in one place is more beneficial to your bottom line. These use cases illustrate when a user should employ a data warehouse instead of a data mart. In short, a data mart is simpler than a data warehouse, storing data from one department rather than the entire company.
- Data Extraction – the process of collecting or retrieving data from a variety of sources for further data processing, storage or analysis elsewhere.
