Data cleansing

[ericdelaqua]

Hello,

I am trying to cleaning records and need some help to achieve my expected output below.

I have table1  and table2, I need to build a 3rd table as shown below based on the first 2 tables.

Table1:

values	number
ab	12
cd	34
ef	42
gh	76

Table2
cat	values2
1	(cd&gh)-ef
2	ab+ef

Expected Table

Cat	Defined
1	(Sum({<values={'cd'}>}number)+Sum({<values={'gh'}>}number))-Sum({<values={'ef'}>}number)
2	Sum({<values={'ab'}>}number)+Sum({<values={'ef'}>}number)

Thanks for your assitance

I don't really understand how theses three tables are related, they do not seem to have a common association. Cleansing data usually implies that you alter the incoming data record sin some way during load, but your expected out come looks more like a front-end aggregation using set analysis.

Are you trying to do this in your data model or in a visualization?
Can you share more details on what you are trying to accomplish?

hi Tko,

The table do not need any association there are just sets of data out of which we can pull the 3rd table and they will not be needed any longer. The third table is all that is needed and will associate nicely with a different model once defined.
I hope this clarifies.

Thanks
