The document discusses using the Data Vault 2.0 methodology for agile data mining projects. It provides background on a customer segmentation project for a motor insurance company. The Data Vault 2.0 modeling approach is described as well as the CRISP-DM process model. An example is then shown applying several iterations of a decision tree model to a sample database, improving results with each iteration by adding additional attributes to the Data Vault 2.0 model and RapidMiner process. The conclusions state that Data Vault 2.0 provides a flexible data model that supports an agile approach to data mining projects by allowing incremental changes to the model and attributes.

DATA VAULT 2.0 METHODOLOGY FOR DATA MINING Advantages • Agile project management for DWH projects • Automation and generation • Rapid adoption to changes in the model • Incremental build-out = incremental cost control • Targeted delivery = two week sprints • Predictable and measurable results Disadvantages • Focus on loading of raw data and the production of information • Not many data mining references • Many concepts in the methodology are not applicable for data mining projects • Difficult scaling of team sizes in data mining projects 12.02.2014 Agile Data Mining with Data Vault 2.0 12
