Abstract
A heterogeneous distributed database system (HDDBS) is a federation of pre-existing and autonomous databases. An HDDBS is different from a homogeneous distributed database system in that its local database systems (LDBSs) are autonomous.
Traditionally, a database system is modeled, from the view point of transaction management, as a set ofdata and a set of transactions accessing the data. This basic model, although very simple, is powerful enough to be used to develop serializability theory, the standard model for database concurrency control.
