| Sumario: | This paper presents a synthesis of the methods proposed up to date to solve the view update problem in relational databases. Two basic approaches have been proposed to solve this problem. The first one suggests treating views as abstract data types so that the definition of the view includes all permissible view updates together with their translation. The second approach is to define a translator. Inputs to the translator are a view definition, a view update request and the current database. The output is the database update that translate the view update. |
