What is data granularity in a data warehouse?
Granularity refers to the level of detail or summarization in the units of in the data warehouse (Inmon, WH 2002). For example, one of the dimension might be a date/time dimension which could be at the year, month, quarter, period, week, day, hour, minute, second, hundredths of seconds level of granularity. High granularity means that the data is at or near the transaction level, which has more detail. Low granularity means that the data is aggregated, which has less detail.

What is Data Warehousing and Data Mining?
data warehouse A data warehouse is the main repository of an organization's historical data, its corporate memory. It contains the raw material for management's decision support system. The critical factor leading to the use of a data warehouse is that a data analyst can perform complex queries and analysis, such as data mining, on the information without slowing down the operational systems. data mining The development of computational algorithms for the identification or extraction of structure from data. This is done in order to help reduce, model, understand, or analyze the data. Tasks supported by data mining include prediction, segmentation, dependency modeling, summarization, and change and deviation detection. Database systems have brought digital data capture and storage to the mainstream of data processing, leading to the creation of large data warehouses.

How information can change into data?
