Virtual Private Databases (VPD) allow multiple users to access a single schema whilst preventing them from accessing data that is not relevant to them. Although this type of access can be controlled by the application, access via other methods (SQLPlus) would leave the data open to abuse. A virtual private database or VPD masks data in a larger database so that only a subset of the data appear to exist, without actually segregating data into different tables, schemas, databases. A typical application is constraining sites, departments, individuals, etc Newsgroups: email Date: Mon, 26 Mar 2006 14:31:37 0000 (UTC) Subject: Создание Virtual Private Database в базе данных Oracle.
