Abstract

services, considered in the following, are characterized by the following properties: (i) a name; (ii) a set of functional properties; (iii) a set of nonfunctional properties; (iv) a data schema.  Definition 4 (functional properties): functional properties FP(s)={fp1,...,fpn} of a service s define what the service does for the customer. Each fpi in FP(s) enables a change of state of the real world, coherently with the goals expressed by the users in requirements collection. Considering e.g., a service for “Hotel Reservation”, an associated functional property is “reserve a room” In the following, functional properties will be defined through natural language descriptions, in such a way that they can be seen as an extension of the service names.  Definition 5 (non-functional properties): non-functional properties NFP(s)={nfp1,...,nfpm} of a service s define how the service performs the change of state associated with the functional properties. Non-functional properties have been investigated by several authors, such as (O’Sullivan et al., 2005), (Becha & Amyot 2012), and (Zeng et al., 2004) and they concern technical qualities, business terms and legal aspects of the service. Following our example on the “Hotel Reservation”, examples of NFPs are price and payment options. Let’s note that, since we are considering an abstract service, the NFPs do not assume specific values.  Definition 6 (data schema) The data schema describes at a conceptual level, adopting the Entity Relationship model, the portion of real world on which the service operates. An example of data schema for the “Hotel Reservation” service is reported in Figure 2. 7 Communication of the IBIMA _________________________________________________________________________________

服务存储库集成的方法
以下所述的服务具有以下特性:(i)名称;(ii)一组功能属性;(iii)一组非功能性质;(iv)数据模式。·定义4(功能属性):功能属性FP(s)={fp1,…我们定义服务为客户做什么。FP中的每个fpi都支持真实世界的状态变化,与用户在需求集合中表达的目标保持一致。例如,考虑“酒店预订”的服务,相关的功能属性是“预订房间”。在下面,功能属性将通过自然语言描述来定义,这样它们就可以被视为服务名称的扩展。定义5(非功能性属性):非功能性属性NFP(s)={nfp1,…定义服务如何执行与功能属性相关的状态更改。一些作者已经研究了非功能属性,如(O 'Sullivan等人,2005)、(Becha & Amyot 2012)和(Zeng等人,2004),它们涉及服务的技术质量、商业条款和法律方面。按照我们的“酒店预订”的例子,NFPs的例子是价格和支付选项。请注意,由于我们考虑的是抽象服务,因此NFPs不假设特定的值。•定义6(数据模式)数据模式采用实体关系模型,在概念层面上描述服务运行的现实世界部分。“Hotel Reservation”服务的数据模式示例如图2所示。7 IBIMA的沟通 _________________________________________________________________________________
