What is time granularity?
Time granularity refers to the level of detail or precision at which time intervals are measured or represented. A fine time granularity means that the intervals are small and precise, such as seconds or milliseconds, while a coarse time granularity means that the intervals are larger and less precise, such as days or weeks. The choice of time granularity depends on the specific needs of the system or process being analyzed.
What is the data granularity?
Data granularity refers to the level of detail present in a dataset. It describes the extent to which data is broken down into smaller parts, such as individual data points or intervals. A dataset with high granularity contains more detailed information, while a dataset with low granularity contains broader, summarized data.
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.

Data granularity in a data warehouse?
Granularity refers to the level of detail of the data stored fact tables in a data warehouse. High granularity refers to data that is at or near the transaction level. Data that is at the transaction level is usually referred to as atomic level data. Low granularity refers to data that is summarized or aggregated, usually from the atomic level data. Summarized data can be lightly summarized as in daily or weekly summaries or highly summarized data such as yearly averages and totals.
How does the granularity of information change as it moves from lower to upper organization levels?
As information moves from lower to upper organizational levels, the granularity decreases. Lower levels deal with detailed and specific data, while upper levels focus on more generalized and summarized information. This shift in granularity allows higher-level management to make strategic decisions based on a broader perspective.
What factors affect selection of granularity size for data item?
There are several factors guiding granularity selection: 1) overhead - the more granular the more objects and methods in supporting code, 2) regulatory - there may be compliance mandates specifying what granularity will be maintained in the data, 3) industry practice - your granularity should generally match that of cloud and third-party products if your system will be integrating with these services. For example, do not combine first and last name as a single data item if every one else manages these as two separate data items.
