5.1 Case-based reasoning (CBR)
- Capture and store past experiences as organisational knowledge.
- System searches for stored cases with similar profile to new problem.
- Adds unsuccessful cases to aid learning.
- Built on artificial intelligence technology.
5.2 Online analytical processing (OLAP)
- Provides multidimensional analysis of data to allow user to see data in different ways using multiple dimensions.
- Main technique is to rotate a data cube.
- Also called ‘slice and dice’.
5.3 Knowledge discovery in databases - data mining
- Uses variety of neural network, decision trees and genetic modeling algorithms.
- Use sophisticated data search capabilities using algorithms to discover patterns and correlations in vast amounts of data.
