1	Malleability, obliviousness and aspects for broadcast service attachment Harrison, William January 2010 (has links) An important characteristic of Service-Oriented Architectures is that clients do not depend on the service implementation's internal assignment of methods to objects. It is perhaps the most important technical characteristic that differentiates them from more common object-oriented solutions. This characteristic makes clients and services malleable, allowing them to be rearranged at run-time as circumstances change. That improvement in malleability is impaired by requiring clients to direct service requests to particular services. Ideally, the clients are totally oblivious to the service structure, as they are to aspect structure in aspect-oriented software. Removing knowledge of a method implementation's location, whether in object or service, requires re-defining the boundary line between programming language and middleware, making clearer specification of dependence on protocols, and bringing the transaction-like concept of failure scopes into language semantics as well. This paper explores consequences and advantages of a transition from object-request brokering to service-request brokering, including the potential to improve our ability to write more parallel software. service-oriented aspect-oriented programming language middleware concurrency Data processing Computer science Software Architectures (NEW) Data abstraction (NEW) Domain-specific architectures (NEW) Information hiding (NEW) Language Constructs and Features (E.2) Abstract data types Classes and objects (NEW) Concurrent programming structures Constraints (NEW) Control structures Coroutines Data types and structures Dynamic storage management Frameworks (NEW) Inheritance (NEW) Input/output Modules, packages Patterns (NEW) Polymorphism (NEW) Procedures, functions, and subroutines Recursion
