开源格网之Grid SQL Parallel Query & pyWPS

Today when I try to download some python based postgresql module, I met a new plugin for Postgresql to implement the Grid SQL, which is Grid SQL Parallel Query.GridSQL enables organizations to easily meet complex Data Warehousing and Business Intelligence challenges using true grid technology that implements a shared-nothing, distributed data architecture. GridSQL enables OLAP applications to leverage the power of multiple commodity servers while appearing as a single database to the application. Most important is, Grid SQL is opensource.

look at the figure below, which describe the workflow of Grid SQL.

At the meantime, another opensource module written  by python is pyWPS. WPS is newly released specification by OGC to realize the web map processing. in my point of veiw, the map processing, particularly the GIS analysis has a promising outlook in the near future. By the way, we can use grid sql and pyWPS to make analysis. the grid sql is for retrieving geospatial data, pyWPS is for  transacting.
