enterprise

今天party讨论，意想不到的是竟然对enterprise这个词起了很大的争执，查了一下词霸：
enterprise
n.（名词）
(1)An undertaking, especially one of some scope, complication, and risk.
事业：一项事业，尤其指一项雄心勃勃、复杂、且具危险性的事业
(2)A business organization.
企业：商业机构
(3)Industrious, systematic activity, especially when directed toward profit:
干事业：勤奋，有系统的活动，尤为以获得利益为目的：
Private enterprise is basic to capitalism.
私营是资本主义的基础
(4)Willingness to undertake new ventures; initiative:
进取心：愿意冒新的危险；进取的：
“Through want of enterprise and faith men are where they are, buying and selling, and spending their lives like serfs”(Henry David Thoreau)
“由于缺乏进取心和信仰，人类始终驻足不前，或买或卖，过着农奴般的生活”(亨利·戴维·索罗)

那么在enterprise application这个context里，enterprise究竟什么时候才能做企业讲呢？对于这一点，我的看法是为企业核心业务提供支持的系统。
