analyzing business data, such as sales revenue byproducts and/or departments, or by associated costs

and incomes. BI technologies provide historical,

current and predictive views of business operations.

Better revenues.


37/75

ETL Process

1. ETL stands for Extraction Transformation Loading.


40/75

ETL

1. Data is taken from different sources, lets sayUS and UK.

2. In US database the shoe size is in mm size, InUK database it is in cm size.

3. We need both of them in common format, so

that we can use it for future preditions.

Preserving history for trends analysis

1. Methods :

1.1. Slowly Changing Dimensions 01.2. Slowly Changing Dimensions 11.3. Slowly Changing Dimensions 2

1.3. Slowly Changing Dimensions 3

Slowly Changing Dimensions 0


48/75


The Type 0 method is a passive approach tomanaging dimension value changes, in whichno action is taken. Values remain as they wereat the time of the dimension record was firstentered.



49/75




50/75


The Type 1 methodology overwrites old datawith new data, and therefore does not trackhistorical data at all. This is most appropriate

when correcting certain types of data errors,such as the spelling of a name.



51/75




52/75


The Type 2 method tracks historical data bycreating multiple records for a given naturalkey in the dimensional tables with separatesurrogate key and/or different versionnumbers. With Type 2, we have unlimitedhistory preservation as a new record is

inserted each time a change is made.



53/75




54/75


The Type 3 method tracks changes usingseparate columns. Whereas Type 2 hadunlimited history preservation, Type 3 has

limited history preservation, as it's limited tothe number of columns designated for storinghistorical data.
