Problems about processing a huge amount of data

[deleted_user]

I am doing a project that need to analyze a huge amount of data (around 120 million records). Before doing data analysis, I need to process the data first. data processing like import the data, filtering, grouping,etc.
My raw data file is ASCII file. My idea is either doing data process in SAS or import the ASCII file to database. Can any one suggest the idea for me?

Use SAS. It can handle it! Use the SAS Enterprise Guide interface. I am at a federal government agency with very large data sets. SAS & Enterprise Guide work well for us.
