What was the data?
Answer** why stars don't shine! .
because our sun which also is a star, is hundreds of thousands of light years closer to us than the next nearest star. therefore its light… is also proportionately greater. and during the day it illuminates our atmosphere.
to a greater degree than the light from the other stars , the stars are still shining, you just can't see them any more because they're dimmer than the light which is being refracted into the atmosphere by the sun. this refracted light also gives the atmosphere its blue color which is brighter than star light..
you can kind of demonstrate this in a dark room by lighting a match, it will seem very bright, but if you flip on the light switch, it will seem very dim in comparison to the brighter light of an incadesant bulb. at night the earth blocks out the suns light from our atmosphere and allows the lesser light from the stars to be seen..

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

Like in languages like c we have datatypes such as char for characters , int for integers etc . In database we have datatype to denote the type of the field example numbers for storing integer, Varchar for characters. (MORE)

What is data redundancy and data inconsistency?
Data redundancy is a situation created in a database or datastorage technologies where the same piece of data is held in twoseparate places. This can mean two different fields… in a singledatabase, or two different spots in multiple software environmentsor platforms. However, there are 2 forms of Redundancy - positive and of coursenegative. Negative - excessive or wasteful data redundancy generally occurswhen a given piece of data does not have to be repeated, but endsup being duplicated or triplicated due to inefficient coding orprocess complexities. A positive type of data redundancy works to safeguard data andpromote a consistency. Many developers consider it acceptable fordata to be stored in multiple places. The key to this type becauseit classed perhaps as critical data is to have a master field orspace for this data, so that there is a way to update all of theplaces where data is redundant through one central access pointelse it becomes a problem because users will not always completethe multiple updates. Data inconsistency is a situation which occurs between files whensimilar data is kept in different formats in two different files,or when the matching of data must be done between files. Thisresults of the data inconsistency, these files duplicate some datasuch as addresses and names, compromising data integrity. A classiccase would come programmes store same data in two or more placesand when updates are require to that data one of other of thelocation s is not updated. This needs therefore a single key ormaster field to bring all the areas together at one time to ensureuser update is undertaken (MORE)
