Abstract
A distributed database management system (DDBMS) must simplify the user's task of defining applications which manipulate shared data stored at multiple computing sites. To this end, the DDBMS must support transparent access to remote data. That is, any operation allowed on local data should also be possible on remote data. At the same time, because different computing sites are controlled by different individuals or organizations, the DDBMS must preserve each site's autonomy over its own data. This paper discusses some of the issues raised in the implementation of a DDBMS by the requirements of site autonomy. The issues will be discussed from the perspective of the R ∗ research project at IBM's San Jose Research Lab.
