The objective of the systems analysis phase is to understand the proposed project，ensure that it will support business requirements，and build a solid foundation for system development. The systems analysis phase includes four main activities. （1） involves fact-finding to describe the current system and identification of the requirements for the new system，such as outputs， inputs，processes，performance，and security. （2） refer to the logical rules that are applied to transform the data into meaningful information. （3） continues the modeling process by learning how to represent graphically system data and processes using traditional structured analysis techniques. （4） combines data and the processes that act on the data into objects. These objects represent actual people，things，transactions，and events that affect the system. In （5），we will consider various development options and prepare for the transition to the systems design phase of the SDLC.

A

Outputs

B

Inputs

C

Processes

D

答案：

C

题目描述了系统分析阶段的四个主要活动，其中第三个活动是“数据和过程建模”，指的是继续建模过程，学习如何使用传统的结构化分析技术以图形方式表示系统数据和过程。因此，正确答案是C，即“过程”。
