The "InfoHarness" information integration platform, tools, and services being developed at Bellcore are aimed at providing integrated and rapid access to huge amounts of heterogeneous information independent of the type, representation, and location of information. InfoHarness provides advanced search and browsing capabilities without imposing the burden of restructuring, reformatting or relocating information on information suppliers or creators. This is achieved through object-oriented encapsulation of information and the associated meta-information (e.g., type, location, access rights, owner, creation date, etc.). The meta-information extraction methods ensure rapid and largely automatic creation of information repositories. A gateway that supports access to InfoHarness repositories from …

Using Tickets To Enforce The Serializability Of Multidatabase Transactions, Dimitrios Georgakopoulos, Marek Rusinkiewicz, Amit P. Sheth

To enforce global serializability in a multidatabase environment the multidatabase transaction manager must take into account the indirect (transitive) conflicts between multidatabase transactions caused by local transactions. Such conflicts are difficult to resolve because the behavior or even the existence of local transactions is not known to the multidatabase system. To overcome these difficulties, we propose to incorporate additional data manipulation operations in the subtransactions of each multidatabase transaction. We show that if these operations create direct conflicts between subtransactions at each participating local database system, indirect conflicts can be resolved even if the multidatabase system is not aware of …
