Distributed Information Systems Quiz

Study Notes

Distributed Information Systems:

Goal is to distribute information across several servers
Many distributed systems today are traditional information systems integrating legacy systems
Transactions form an atomic operation where all READ and WRITE operations are executed
Transactions combine a set of related operations into a unit that either completely succeeds or completely fails
Transaction Processing Monitors coordinate the execution of a transaction involving distributed data
Facilities for direct communication between applications, such as Remote Procedure Call (RPC) and Message-Oriented Middleware (MOM), are needed for multiple clients
Pervasive (ubiquitous) computing involves microprocessors embedded in everyday objects
Emerging research topics include distributed systems in which instability is the default behavior, and pervasive systems with small, battery-powered, mobile devices that lack human administrative control
Pervasive applications require devices to continuously be aware of contextual changes and encourage ad-hoc composition and sharing as the default
Examples of pervasive systems include home systems, electronic health systems, and sensor networks
Sensor networks are networks where nodes have the special capability of sensing parameters such as light intensity, temperature, pressure, and velocity
Sensor networks have many nodes, are simple, often battery-powered, and can be considered from a database perspective as distributed systems.
