ClickWatch: Problems with WSN Markus Scheidgen: HWL – A High-Performance Wireless Sensor Research Network Experiments (mostly) unstructured data analysis based on Solution:representation (e.g. log-files) scripts and log-files: § give all data a structure through meta-data and types § record data and meta-data in a database § use type-safe implementations for analysis or even uses model ➡ unsafe transformation (structural transformation) ➡ not reusable ➡ not reproducible ➡ not automated 4
