Abstract Urban climate insurgency refers to the ensemble of grassroots initiatives aiming tackle change from a radical point view. Insurgency in this case does not imply violence but rather rejection current socioecological system. While explicitly challenging planetary ecocide and climate-change effects, these forms target all policies that make urban condition yet more precarious, demonstrati...

A data warehouse (DW) can be seen as a set of materialized views de ned over remote base relations. When a query is posed, it is evaluated locally, using the materialized views, without accessing the original information sources. The DWs are dynamic entities that evolve continuously over time. As time passes, new queries need to be answered by them. Some of these queries can be answered using e...

The data warehouse is subject oriented, integrated, nonvolatile and time-varying data sets, which is used to support management decision-making. A data warehouse stores materialized views of data from one or more sources, with the purpose of efficiently implementing Decision-support or OLAP queries. One of the most important decisions in designing a data warehouse is the selection of materializ...

This paper presents a framework for data integration that is based on using \Squirrel integration mediators" that use materialization to support integrated views over multiple databases. These mediators generalize techniques from active databases to provide incremental propagation of updates to the materialized views. A framework based on \View Decomposition Plans" for optimizing the support of...

In today's multitiered application architectures, clients do not access data stored in the databases directly. Instead, they use applications which in turn invoke the DBMS to generate the relevant content. Since executing application programs may require signi cant time and other resources, it is more advantageous to cache application results in a result cache. Various view materialization and ...

Managed aquifer recharge (or intentional recharge) is a purposeful human intervention designed to supplement natural enrichment processes of groundwater aquifers by various methods. It holds the potential mitigate impact climate uncertainty on irrigated agriculture restoring storage levels in depleted aquifers, economic value which increases during droughts. We use high-resolution dynamic regio...

In any online decision support system, the backbone is a data warehouse. In order to facilitate rapid response to complex business decision support queries, it is a common practice to materialize an appropriate set of the views at the data warehouse. However, it typically requires the solution of the Materialized View Selection (MVS) problem to select the right set of views to materialize in or...

This paper proposes a new life cycle assessment (LCA) statistics method to calculate the energy consumption of Chinese buildings from perspective LCA under sustainable supply chain system. We divide into materialization stage, construction and operation stage. Based on method, we obtain following findings. First, growth total building has slowed down since 2014, its share levels off, remaining ...
