Hello,
We're fairly new to using Cognos (started with 12.0.0 last year), but discovered early on the value of using data sets to improve overall performance compared to data modules for our larger business users. While we've been using the default Parquet files with good results, I'm curious if there are any advantages to using a DB2 database for hosting data sets (aside from eliminating the 2Gb size limit for Parquet files)? We're primarily a Microsoft SQL shop so our experience with DB2 is mostly nonexistent, so go easy on me 🙂
