In the last few years Software as a Service (SaaS) has changed
from curiosity generating concept to an accepted mainstream
concept.SaaS has transformed the way software is being
delivered to the customer.This transformation has been possible
with maturing technologies and the web becoming the primary
medium of communication and collaboration.SaaS is a software
delivery paradigm where the software is hosted off-premise and
delivered via web to a large number of tenants and the mode of
payment follows a subscription model.
Configurability is one of the keystones to the success of any SaaS
software.Configurability allows the single instance multiple
tenant model which leads to many benefits both for the customers
and the vendors which in turn has led to the acceptance and
popularity of SaaS.Configurability in SaaS software aims to
provide tenants/customers with a multitude of options and
variations using a single code base,such that it is possible for
each tenant to have a unique software configuration.How to
capture and represent configuration data is an important
consideration when designing for configurability in SaaS
software.
This paper addresses the issue of how to effectively and
efficiently support configurability in SaaS software and proposes
SaaS architecture to support configurability.A proof of concept
implementation is done to support configurability with the
configuration data in xml format.The paper aims to provide
information on the nature of configurability in SaaS software,
how it can be provided and the technologies needed to support it.

最近几年来,“软件即服务”已经从一个激发人们好奇心的概念变为一个为公众接受的主流概念.“软件即服务”改变了软件到达用户手中的路径.是技术的成熟以及网站成为通讯和合作的主要媒介使得这一改变成为可能.“软件即服务”是一个软件传递模式,在这个传递模式中,软件被作为备用设备,通过网络传送到大量的用户手中,而付款则是以缴纳服务费的方式进行.
高配置性是所有“软件即服务”型的软件获得成功的关键.它们的高配置性实现了一个软件—--多个用户的服务模式,这样就让用户和供应商都能从中获利不少,而且还让“软件即服务”受到更为广泛的认可和更多人的欢迎.“软件即服务”型软件的高配置性目的在于通过一个单一的码基数给用户提供更多的选择和变体,从而使每一个用户都能有一个独特的软件配置.在构思“软件即服务”型软件的高配置性时,怎样获得和发放配置数据是一个着重考虑的问题.
这篇文章论述了怎样有效地支持“软件即服务”型软件的高配置性,并为“软件即服务”支持高配置提出了建议.这一理念的实施在经过证明后,被用以支持高配置性,并提供了xml格式（可扩展标记语言格式）的配置数据.这篇文章旨在提供多方面的信息,包括“软件即服务”型软件的高配置性的本质,它怎样提供高配置,以及提供高配置所需要的技术支持.
