Run time optimization of benchmark analyses

The data is exported as CSV files, which are necessary to prepare company-internal yield and money market benchmark data within the scope of performance analyses. To reconcile different calculation procedures, a reconciliation of benchmark amounts and attribution effects is performed for attribution analyses between the company-internal and outsourced calculations. Reconciliation is performed on a daily basis and in a runtime-critical environment and is therefore particularly time optimized.  Aim: Runtime optimized daily reconciliation of benchmark calculation data.
