Virtual private database

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. to operate only on their own records and at the same time allowing more privileged users and operations (e.g. reports, data warehousing, etc.) to access on the whole table.
