A Hybrid Architecture for Implementing Efficient Geospatial Web Services: Integrating .Net Remoting and Web Services Technologies

Pouria Amirian, Ali Alesheikh
2008 Journal of Applied Sciences  
Using standard geospatial Web services together with efficient technologies provide different kinds of message exchange patterns for various kinds of clients facilitate to share and access to geospatial  ...  But, there are two important barriers in front of sharing and accessing geospatial data; non-interoperability and insufficient message exchange patterns of geospatial processing systems which are widely  ...  Semantic heterogeneity arises as a result of incompatibility in meanings of data. Syntactic heterogeneity of geospatial information systems can be categorized in data and access heterogeneity.  ...

On the energy efficiency of client-centric data consistency management under random read/write access to Big Data with Apache HBase [article]

Álvaro García-Recuero
2016 arXiv   pre-print
Employing a client-centric consistency approach, and while honouring ACID properties of the chosen columnar store for the case study (Apache HBase), we present the factors involved in the energy consumption  ...  and the access patterns applied (sequential vs random memory accesses).  ...  Therefore, for analyzing the effect of deferring or not updates under a strongly consistent architecture, we embed these semantics into the HBase client of YCSB (Yahoo Cloud Service Benchmark ).  ...

Dynamic Web Services on a Home Service Platform

André Bottaro, Eric Simon, Stéphane Seyvoz, Anne Gérodolle
2008 22nd International Conference on Advanced Information Networking and Applications (aina 2008)  
Distribution and heterogeneity are managed by service-oriented drivers leveraging the "service platform" concept.  ...  Its openness to dynamic distributed and heterogeneous devices brings great challenges in home application design. We present here an open architecture for home service development.  ...  This service-oriented design, which relies on the design pattern named Service Locator [9] , characterizes the service platform concept used in this article.  ...
