3 Apa itu KDD??

4 Knowledge Discovery in Database
Definition ”the non-trivial extraction of implicit, previously unknown and potentially useful knowledge from data” (Fall, 2003) Knowledge discovery in databases (KDD) is the process of discovering useful knowledge from a collection of data. (Romi, 2010)

10 OnLine Analytical Processing (OLAP)
”the dynamic synthesis, analysis, and consolidation of large volumes of multi-dimensional data” Focuses on multi-dimensional relationships among existing data records

11 Olap Vs. SQL OLAP : Menambahkan Analisis dalam Tools
SQL : eksekusi roll-up, drill-down, slice, dice, pivot dari DW

12 OLAP differs from data mining
– OLAP tools provide quantitative analysis of multi-dimensional data relationships – Data mining tools create and evaluate a set of possible problem solutions (and rank them) • Ex: Propose 3 marketing strategies and order them based on marketing cost and likely sales income

13 Architectures for OLAP
Ada 3 Arsitektur for OLAP – Relational OLAP (ROLAP) – Multi-dimensional OLAP (MOLAP) – Managed Query Environment (MQE)
