Abstract:The focus of this thesis is on the storage part of a sensor management system. Sensor data can already be enormous, but because every measurement stored can also contain multiple annotations the total size can really explode. Besides this, annotations are not necessarily bound to a single measurement, but can also be attached to multiple sensors and on time spans. This creates challenges in storing the data efficiently while also maintaining efficient retrieval. On the retrieval side there are all kinds of queries possible on the sensor data, annotations, time or combinations of those. To provide efficient storage for all these types of queries makes things even more challenging, because every storage method has its advantages and disadvantages. This thesis looked into a number of methods which try to solve these problems. Three of these methods were chosen and tested on scalability after which the most scalable was implemented into an open-source software package. This implementation was tested again on scalability.
