CAUSE

(35%+) §  Some reports are used

infrequently §  Several reporting solutions only

used temporarily

EFFECT

Situation §  No classification of data into

important/unimportant §  Data growth due to high

granularity of data §  Long ETL runtimes regardsless

of several optimizations

Key take aways – Paving the Road to HANA

System analysis - Know where you are

Build a plan - your very personal Road to HANA

Based on the assessment we present to you improvement potential and short term benefits, including a review of your HANA sizing, housekeeping and archiving potential.

Data Model and ETL changes

Start adopting Data Models, Lookups and Transformations that could be optimized for the use under HANA.

Code optimization: optimize customer code and replace non-compatible code.

Clean up & optimize your system already now

Archive/NLS: to move inactive data into a highly compressed store.
