Description
The Geo-Integrator Storage module provides the central database system with spatial feature functionality and operation. This is probably the most central and thus most important module if you manage any data of your own. Therefore it should be easy to import and export data, operation of the system should meet highest standards of stability and allow for replication, triggers and stored procedures. All these parameters are currently only met by the the spatial language extension PostGIS for the object relational database PostgreSQL.
Functionality
Spatial data management within a DBMS (database management system). Import of spatial data as WKT, WKB or by using the Free Software library OGR. Export as SQL dump, OGR, SQL-scripting or through the OGC WFS interfaces of UMN ~MapServer, ~GeoServer or deegree WFS. Indexing for performance optimization using GIST (PostGIS built-in). OGC standardized spatial operations (inside, outside, buffer, intersect, etc.) is implemented using the GEOS library (C-implementation of the JTS - Java Topology Suite).
Standards
The Geo-Integrator Storage module meets the OGC standards for Simple Feature for SQL (SFSQL). Hence, any application observing these standards can access the database.
Technology
Geo-Integrator Storage is based on the Free Software project PostGIS, the spatial SQL extension for the Free Software object-relational database PostgreSQL.
