 Attribute processing and queries in GRASS GIS can take an advantage of latest developments
 in database management systems (DBMSs) as several DBMSs are supported most notably SQLite and PostgreSQL.
+A PostGIS database can be connected including it geometry and topology.
+In parallel to that native support the OGC Simple Features is available.
 
-Non-topological vector
-data are automatically converted to a topological representation upon import. Further more, various cleaning tools exist
-to remove non-trivial topological errors.
-
 The GRASS GIS 7 releases come with faster vector processing backend
 and more efficient internal vector format;
 both disk and memory requirements were reduced.
 The new spatial index performs queries faster (more than 10 times for large vectors compared to GRASS GIS 6).
 
-All topological cleaning tools have been optimized with regard to processing speed, robustness, and system
-requirements.
-
-Considering the wide spread usage of Esri Shapefile, a non-topological format for vector data exchange, it is particularly
-advantageous that GRASS GIS 7 offers advanced cleaning tools.
-
-postgis incl topo
-GRASS GIS 7 supports various data sources in read and write access. Beside native file-based raster and vector format
-GRASS allows to specify external data sources through GDAL/OGR library. GRASS GIS 7 also natively supports
-PostGIS database including its topological extension.

-In parallel to that native support the OGC Simple Features was added.

 \block{\blocktitlewrap{Vector Network Analysis}}{
-All vector network analysis tools provide now fine control over node costs.
+In 2003 Radim Blazek introduced shortest path analysis (\gmodule{v.net.path}),
+traveling salesman (\gmodule{v.net.salesman}),
+and several other modules for vector network analysis (staring with \gmodule{v.net}).
+Over the years, the number of available algorithms increased to over 15 modules
+including for example, centrality measures and connected components added in 2009 by Daniel Bundala.
+In 2014 Stepan Turek implemented turns support into all relevant vector network modules.
