ContextConformance between architecture and implementation is a key aspect of architecture-centric development. Unfortunately, the architecture “as documented” and the architecture “as implemented” tend to diverge from each other over time. As this gap gets wider, the architects’ reliance on architecture-level analyses is compromised. Thus, conform...

There is a good consensus on the strategic value of Service Oriented Architecture (SOA) as a way of structuring systems, and a common trend is to migrate legacy applications that use outdated technologies and architectures to SOA. We study the effects in the resulting Web Service interfaces of applying two traditional migration approaches combined...

Each phase produces a set of deliverables following different documentation standar...

Planning algorithms are often applied by intelligent agents for achieving their goals. For the plan creation, this kind of algorithm uses only an initial state definition, a set of actions, and a goal; while agents also have preferences and desires that should to be taken into account. Thus, agents need to spend time analyzing each plan returned by...
