Associations between objects are one of the most fundamental concepts in object-oriented design. the choices of how to implement associations determine how operations on the associated instances are performed: Sequentially or in parallel, with or without cached results, and with a transient or persistent effect. In this work, we propose a scheme that allows for generated code to support different methods of operating on associated instances, without requiring changes to the client code. these methods include using indices, traversing the association in parallel, or using a database. Instead of the sequential iterator interface, we propose to use an interface that include operations over multiple instances: Foreact. Filter, Map and Fold. this interface allows for realizing designs that involve sending messages to multiple associated instances, such as UML sequence and communication diagrams. the realization does not depend on the implementation details of the associations.

Designing a software system's architecture properly is one of the most important tasks of any softwareengineering project. Nevertheless there exists no common definition of the term 'software architecture' and no standard software architecture description language (ADL). this paper discusses whether the standard OO modeling language UML is a standard ADL, explains some deficiencies if used for this purpose, and makes a proposal of how to eliminate these deficiencies. the proposal is based on the widely accepted idea that elements of the component-based OO modeling language ROOM should be integrated with UML. It explains why the idea of merging static structure diagrams of ROOM with behavior describing collaboration diagrams of UML is not sufficient and presents an additional approach for the integration problem.

the world is moving towards automation and autonomous systems, in which devices are expected to be seamlessly integrated and complex, which act on our behalf and deliver better quality services anywhere anytime and in any fashion. However most of the Electrical Power Supply Companies across the world still use the good old traditional approaches for home related services pose big challenges for home automation. Author proposes a novel computing model to achieve an autonomous environment for home automation. A model is based on agent technology in which agents are assigned certain tasks to achieve. the architecture is portable, flexible and can easily integrated with other architectures.

softwaresystemsthat execute in embedded and pervasive environments are frequently required to be self-monitoring, self-adapting, and self-healing. However, supporting these self-* capabilities in pervasive environments creates a number of unique engineering challenges. this paper first describes the challenges that we believe to be the most significant based on our experience developing real-world pervasive software applications with self-* capabilities. We then discuss each challenge in the context of four strategies commonly employed in self-* systems: dynamic software update, service discovery, transparent replication, and logical mobility. Finally, we explain how each strategy is implemented in our architectural middleware platform, Prism-MW. Copyright 2007 ACM.
