Dear aaliya zarrin,

maybe you should have a look at some GRASS tutorials and manuals for an
introduction to GRASS and data models and formats.

for design and structure of GRASS and data formats you can start here:
http://www.gdf-hannover.de/lit_html/grass60_v1.2_en/node7.html

for importing vector data you may start here:
http://www.gdf-hannover.de/lit_html/grass60_v1.2_en/node27.html

for first steps in GRASS with vector data you can start here:
http://www.gdf-hannover.de/lit_html/nutshell_v10_en/node14.html

more tutorials etc. can be found here:

hope that helps,

usually, you can use v.in.* modules for it. most of the module names are
clear. for other types, use v.in.ogr, which uses OGR library. see
http://remotesensing.org/gdal/ogr/ogr_formats.html for supported formats

all, which are belongig to your vector format. see

g.manual v.in.ascii
g.manual v.in.db
g.manual v.in.ogr
and others

for details
