Data Warehousing
The best way to know about something is to first learn about it. So here were are discussing about the Data Warehouse Training. First we should know what is
Data Warehousing?
Data Warehouse Intelligence is a term to describe a system used in an organization to collect data, most of which are transactional data, such as purchase records and etc., from one or more data sources, such as the database of a transactional system, into a central data location, the Data Warehouse, and later report those data, generally in an aggregated way, to business users in the organization.
This system generally consists of an ETL tool, a Database, a Reporting tool and other facilitating tools, such as a Data Modeling tool. A data warehouse (DW) is a database used for reporting. The data is offloaded from the operational systems for reporting. The data may pass through an operational data store for additional operations before it is used in the DW for reporting.
A data warehouse maintains its functions in three layers: staging, integration, and access. Staging is used to store raw data for use by developers (analysis and support). The integration layer is used to integrate data and to have a level of abstraction from users. The access layer is for getting data out for users.
History
The concept of data warehousing dates back to the late 1980s When IBM researchers Barry Devlin and Paul Murphy developed the "business data warehouse". In essence, the data warehousing concept was intended to provide an architectural model for the flow of data from operational systems to decision support environments.
The concept attempted to address the various problems associated with this flow, mainly the high costs associated with it. In the absence of a data warehousing architecture, an enormous amount of redundancy was required to support multiple decision support environments. In larger corporations it was typical for multiple decision support environments to operate independently. Though each environment served different users, they often required much of the same stored data.
