Hye readers , assalamualaikum.
Today i'm going to comment about data warehouses. Data warehouse is a logical collection of information - gathered from many different operational databases that supports business analysis activities and decision making task. For example metric number.
Next is ETL - extraction, transformation and loading. it is a process that extracts information from internal and external databases , transform the information using a common set of enterprise definitions and loads the information into a data warehouse.
Then , data mining. It is the process of analyzing data to extract information not offered by the raw data alone.
Besides that , this topic also have information cleansing or scrubbing. An organization must maintain high quality data in the data warehouse. It is a process that weeds out and fixes or discards inconsistent, incorrect, or incomplete information.
Lastly is business intelligence. business intelligent is the information that people use to support their decision making effort. principle business intelligent enabler includetechnology , people and culture
