Bring together data from new and diverse sources with Cloudera Data Warehouse.
An Enterprise Data Warehouse is a system used for reporting and data analysis, and is considered a core component of business intelligence.
Data warehousing is the process of constructing and using a data warehouse. A data warehouse is constructed by integrating data from multiple heterogeneous sources that support analytical reporting, structured and/or ad hoc queries, and decision making.
A data warehouse is a type of data management system that is designed to enable and support business intelligence (BI) activities, especially analytics. Data warehouses are solely intended to perform queries and analysis and often contain large amounts of historical data.
A Data Warehouse works as a central repository where information arrives from one or more data sources. Data flows into a data warehouse from the transactional system and other relational databases
Data Warehouse Infrastructure
The virtual data architecture of a warehouse is physically managed atop one or more data platforms, including traditional relational database management systems (RDBMSs), newer DBMSs (for columns, NoSQL, and graph), file systems (of which Hadoop is becoming increasingly common), and object stores (typically cloud-based).
It also includes a highly diverse ecosystem of tools, such as those for reporting, analytics, integration, quality, metadata, development, and administration.
Finally, for speed, scale, interoperability, and high availability all the above infrastructure components rely heavily on underlying enterprise hardware—namely CPUs, server memory, networks, storage, and clouds.
Application of Data Warehouse
One of the most important sector which utilizes data warehouses is the Healthcare sector.
A major proportion of this industry is dominated by hotel and restaurant services, car rental services, and holiday home services.
The design of tailor-made customer offers and promotions is also possible through warehouses.
Retailers serve as middlemen between producers and consumers. They need to maintain records of both parties to ensure their existence in the market.
Data warehouses find themselves to be of use in the service sector for maintenance of financial records, revenue patterns, customer profiling, resource management, and human resources.
