Abstract:

Data management is the organization of information to support efficient access and analysis. For data intensive computing applications, the speed at which relevant data can be accessed is a limiting factor in terms of the size and complexity of computation that can be performed. Data access speed is impacted by the size of the relevant subset of the data, the complexity of the query used to define it, and the layout of the data relative to the query. As the underlying data sets become increasingly complex, the questions asked of it become more involved as well. For example, geospatial data associated with a city is no longer limited to the map data representing its streets, but now also includes layers identifying utility lines, key points, locations and types of businesses within the city limits, tax information for each land parcel, satellite imagery, and possibly even street-level views. As a result, queries have gone from simple questions, such as “how long is Main Street?”, to much more complex questions such as “taking all other factors into consideration, are the property values of houses near parks higher than those under power lines, and if so, by what percentage”. Answering these questions requires a coherent infrastructure, integrating the relevant data into a format optimized for the questions being asked.
