2013 Big Data Computing  
This chapter proposes steps towards the solution to the data access problem that end-users typically face when dealing with Big Data: • They need to pose ad hoc queries to a collection of data sources,  ...  possibly including streaming sources; • They are unable to query those sources on their own, but are dependent on assistance from IT experts; • The turnaround time for information requests is in the range  ...  While database-based temporal querying approaches or RDF-based temporal and streamquerying approaches as discussed above offer fast performance for large data and massive streams with high data rates,  ...

Smart Query Answering for Marine Sensor Data

Md. Sumon Shahriar, Paulo De Souza, Greg Timms
2011 Sensors  
We review existing query answering systems for sensor data. We then propose an extended query answering approach termed smart query, specifically for marine sensor data.  ...  The smart query answering system integrates pattern queries and continuous queries. The proposed smart query system considers both streaming data and historical data from marine sensor networks.  ...  The latter approach is known as stream (in-network) query processing. These two approaches of query processing based on data storages for sensor data are shown in Figure 2 .  ...
