  19. DWHsing - Trends • DWHs become mission critical -> HA • DWHs grow faster and unpredictable-> scale out • DWHs need to be more cost effective-> use of commodity hardware & storage -> cluster architecture

  20. <Insert Picture Here> Oracle Rac - DWHcustomer example

  21. Facts (2003) Two strong brands • Nr. 1 mailorder company in germany • 30% market share in germany • 140 daughter companies • present in 22 european countries • 10.000 stationary, supporting units/shops in europe • 65 mio shipments / year • 38 mio main catalogues p. a. • 95% brand knowledge Kennzahlen (2002) Quelle - Mailorder

  22. CRM-Actions Campagn-Management Data Mining, Customer Scoring, Analysis MIS, Reporting Computing Power 30% 30% 30% Granular Data Warehouse Source Systems Usage of the DWH

  23. Example : Reporting Individual Reporting: • Discoverer-Solution • Developed for specificuser requirements • User kann create own reports and layout(Slice/Dice Drill up/down)

  24. Example : Analytical CRM (buying power vs. ... )

  25. Analytical CRM Advertising media • Time series analysis, advertising impact, ABC-Analysis, customer development • Advertising success control in the area of target markets • Compaign controlling, customer scoring Article • Top / Bottom Analysis, fast seller analysis, retour analysis • Basket analysis Credit-Risk • Credit risk analysis per client / category / payment method • Identify of credit risk factors / fraud pattern analysis ... Customer • Customer Profile, Customer Scoring • Customer Segmentation (buying behavior, Cross-Buying, etc.), customer development models • Allocation: target market – advertising – assortment – service • Identification of customer irritation and churn Processes • Analysis of process change (ordering, delivery, retour, payment, goodwill) • Quality Monitoring etc.

  26. <Insert Picture Here> DWH architecture

  27. SUN E10k • EMC ... once upon a time .... a DWH platform was seached ... • Benchmark of several hardware vendors :- HP- Sun- Bull- Tandem- IBM- ....... • ... and the winner was :

  28. HP Superdome • HP EVA ... some years later .... a new DWH platform was seached with a better price performance ratio ... • ... and the winner was :

  29. New goals for Quelle‘s DWH • Consolidation of all Marketing-DWHs of mail-order devision • Building one platform for DWH-Applications • Basis for scalability of computing power and storage without completechange of HW / SAN - normal growth (add now nodes / add additional storage) - cope with short-term peaks through load balancing and reconfiguration of existing ressources. • Increase availability through fail-over scenarios • Ressource sharing of DB-near services (IAS – SSO – Applications) • Cost saving

  30. ... some years later .... They replaced the HP Superdomes with a Oracle RAC – Blade infrastructure

  31. Hardware Architecture & Cost (Capex) • Nodes : 12x DL585 – each 15k EUR = 180.000 EUR (32MB RAM – Xeon64 3.66 Ghz) • Infrastructure / Switches / FC = 35k EUR(2 GB / I/O Throughput) • Disc Subsystem 3x EVA8000 – each 250k = 750k (17 TB Net capacity / Raid 1) • Total 1.000.000 EUR

  32. Software Architecture • OS : Suse Linux 64bit • Disk Layout : Oracle ASM • DB – Software : Oracle 10g • Backup & Recovery : Oracle RMAN / ILM (planned) • System Mgmt : OEM – Diag / Tuning / Change / Conf • DB-Options : Partitioning Option Real Application Cluster ETL Option (OWB) • Reporting : OBI-SE – OBI-EE(new strategic deal !)

  37. Administration of the DWH • 3 shifts / 3 DBA per shift managing 100 Oracle DBs • DWH administration : - System / DB admin ~ 4 month / year ~ 0.3 FTE - Disk admin ~ 1 month / year ~ 0.1 FTE - B/R admin ~ 1 month / year ~ 0.1 FTE • Total DWH admin 0.5 FTE

  38. Downtime management • current SLA’s allow 2 days downtime • max planned downtime since cluster – 4h • max unplanned downtime since cluster – 0h
