Abstract:

 Although  deductive  databases  is  based  on  a  well  est ablished  formalism,  they  didn't  know  the  expected  success. 
Their use was limited to the academic purpose. Inde ed, the deductive database management systems are j udged abstract, rare 
in commercial offers, and often expensive.  In amon g the abstract concepts of the deductive databases, we mention the case of 
the  negation  and  its  treatment  by  the  stratificatio n.  In  this  paper,  we  propose  a  convivial  approach  t hat  aims  to  make 
transparent theses concepts relatively abstracted a nd to permit a friendly usse of deductive databases  and stratified database. 
This  approach  permits  to  simplify  concepts,  which  a lways  remain  delicate  for  this  type  of  databases  users  or  designers,  like 
(1)  the  definition  of  a  deductive  and/or  stratified   database  (2)  the  study  of  the  stratifiability,  (3)  the  determination  of  the 
maximal  stratification,  (4)  the  incremental  definit ion  of  strata  and  (5)  the  checking  of  integrity  con straints.  These  operations 
become  more  delicate  if  the  database  is  voluminous.   The  proposed  system  supports  rules  update  and  is  n ot  limited  to  facts 
updating as in known deductive systems. This approa ch is implemented and validated with VI_SDB tool ba sed on an extension 
of predicates nets.
