IBM Systems Journal, 1988
This paper describes, in general terms, distributed database and its relationship to Systems Application Architecture (SAA). It shows the importance to effective distribution of IBM's Structured Query Language (SQL), the database element of the Systems Application Architecture Common Programming Interface (SAA CPI).

Distributed database development
Computer Communications, 1988Abstract Centralized databases have been in large-scale use in the data processing industry since the early 1970s. Distributed databases are very much more sophisticated than centralized databases, and they involve complex software to handle problems such as concurrency control, deadlock prevention and the maintenance of data integrity during multi ...

Directions in Distributed Databases
1988Distributed databases are at a crucial point of development: the first commercial products are becoming available, and companies are faced by a new challenging trade-off between the flexibility, ease of use, and reliability of distributed databases on one side, and the technical complexity of developing truly distributed database applications on the ...

Distributed databases and peer-to-peer databases
ACM SIGMOD Record, 2008The need for large-scale data sharing between autonomous and possibly heterogeneous decentralized systems on the Web gave rise to the concept of P2P database systems. Decentralized databases are, however, not new. Whereas a definition for a P2P database system can be readily provided, a comparison with the more established decentralized models ...

Database integration in a distributed heterogeneous database system
1986 IEEE Second International Conference on Data Engineering, 1986This paper describes the approach to database integration in a heterogeneous distributed database environment utilized by the Amoco Distributed Database System (ADDS). We start with the definition of the extended relational data model that is used by ADDS for database integration.

Architecture for an Intelligent Distributed Database
13th Euromicro Conference on Parallel, Distributed and Network-Based Processing, 2005In this paper we present an architecture for an intelligent distributed database. It integrates different kinds of database, such as relational, object-oriented, temporal, knowledge, deductive and multimedia databases, among others. In our approach we are using concepts from federate databases, fuzzy classified systems; and a database integration ...

A Distributed Mobile Database Architecture
2011 IEEE Asia-Pacific Services Computing Conference, 2011This paper describes architecture for mobile databases where data is distributed over mobile devices. We propose strategies for query execution during mobility. The underlying architecture is based on 3G telephone networks.

Data Integration in Distributed Databases
IEEE Transactions on Software Engineering, 1987Data integration in a distributed database refers to the production of union-compatible views for similar information expressed dissimilarly in different nodes. Such a facility is needed for location transparency and for easier formulation of global queries over the apparently incompatible data aggregated from different nodes.

Rethinking integrity [distributed databases]
IEEE Concurrency, 1997In practice, no real database enjoys complete integrity, a variety of factors conspire to make some information stale, missing, or just plain wrong. System design and analysis should recognize that real systems lack integrity to some degree, most, if not all, of the time. Significant benefits flow from such recognition.

Spatially distributed databases on sensors
Proceedings of the 8th ACM international symposium on Advances in geographic information systems, 2000We consider the problem of data dissemination in a sensor network. First we introduce a cost model for data dissemination in such networks. The model quantifies the tradeoff between the inconsistency of the data, and its transmission cost; the transmission cost is given in terms of energy and bandwidth.
