Tabular
information available to the CSCF is managed by the relational system of
database management ORACLE and thus distributed in various inter-connected thematic
files. Information relating to the
observations is gathered in a file so called principal (CAPT) connected by
numeric or alphanumeric digital codes, with secondary decoding files. With the
latter belong the systematic files (ORDERS, FAMILIES, and SPECIES), those identifying
the recognised habitats (TYPOLOGY), the sampling procedures (METHODS), the
communes (COMMUNES) or observers (LEG) for example.
The
layers of spatial information (digital field model, biogeographic areas,
federal inventories, lakes and rivers...) are managed by the system ArcGIS
(ESRI). The link which unites them with
the tabular information is ensured by the geographical coordinates associated
with the observations of the principal database files.
