Data Warehousing and Business Intelligence (DMBI)
- Data warehousing provides architectures and tools for business executives to systematically organize, understand, and use their data to make strategic decisions.
- A data warehouse refers to a database that is maintained separately from an organization’s operational databases.
- Data warehouse systems allow for the integration of a variety of application systems.
- They support information processing by providing a solid platform of consolidated historical data for analysis.
- According to William H. Inmon, a leading architect in the construction of data warehouse systems, “A data warehouse is a subject-oriented, integrated, time-variant, and nonvolatile collection of data in support of management’s decision-making process”
- The four keywords, subject-oriented, integrated, time-variant, and nonvolatile, distinguish data warehouses from other data repository systems, such as relational database systems, transaction processing systems, and file systems.
