Customer Example
Starting pointApprox. 290 gigabyte DB size and approx. 15 gigabyte DB growth
per month
Aim
Reduction of DB growth rate to:
Reduce hardware costs
Maintain stable system performance
Response times and system administration
Faster implementation of support packages and upgrade projects
Local currency conversion
Archiving
19 archiving objects from FI, CO, MM, SD, and HR
Result (October 2000)
