Granularity of Services

Granularity Metrics for IT Services

Many articles discuss the design of fineor coarse-grained IT services without defining what granularity exactly means. However, this is important to know since the granularity influence e.g. the reusability or the composition effort of services and thus the development, maintenance and composition costs of a service realization. Therefore, we present different metrics to evaluate and compare th...

Granularity of Services - An Economic Analysis

Service-oriented architectures are widely discussed as a design principle for application and enterprise architectures. Nevertheless, an adequate granularity of services from an economical perspective has not yet been researched sufficiently. The finer the granularity to realize the functions of a process, the higher is the number of services and the more effort has to be spent to compose them....

Web services for time granularity reasoning

Handling Temporal Granularity in Situation‐based Services

In many application fields such as disaster management or personal planning, efficient mobile services should capture users' context in order to provide them with the most appropriate information at a given time. Situation‐based services aim toward this direction. They go beyond location‐based services as they take a user's current situation into account. Situations include user profiles togeth...

Web services for time granularity reasoning ∗ Extended

We first briefly illustrate the concept of time granularity and review the emerging approaches for modeling and reasoning with it. We then advocate the need for a set of web services that distributed applications can use to define and manipulate time granularities. As an example of these services we discuss in detail the GSTP service, a constraint solver for networks of temporal constraints wit...
