[Haskell-cafe] Got it working, now trying to abstract it

[Günther Schmidt]

Hi all,

I'm finished with my implementation, an app that analyses financial data  
for budgeting. But there are no abstractions in my code whatsoever,  
everything is coded exactly to the point.

So now that I'm done I'd like to start it over, this time using far more  
abstractions than I have, I was thinking along the lines of creating a DSL  
for it first.

The aspects I have to consider are two-fold:

	ETL-ish - I need to assemble the "records" from a set of csv files
	BI-ish  - I need then to group, filter and aggregate the data.

I've come across "How to write a financial contract" S. Peyton Jones in  
the "fun of programming" and it gives me some ideas on how to go about the  
BI-ish part of the application.

Does anyone know of a DSL example which could fit the bill?
