I have multiple csv files that I want to manipulate(calculate mean, sum, etc.) and after that I want to store them in a SQLite database.
But I want to know what is the most proper way to do that.
CSV to SQL and manipulate with Pandas
OR
CSV, manipulate with Pandas and store in SQL
For example, I want to store all the data in this table http://financials.morningstar.com/ratios/r.html?t=GOOG®ion=USA&culture=en-US. I will update yearly and add 2013,2014,etc. In my SQL table. I'll create a column where I will have 10 year average for each rows, etc.
