系统流程图的作用及符号表示英文回答：
System Flowchart.
A system flowchart is a graphical representation of a system's processes, data flows, and storage. It helps visualize and analyze the flow of information and materials through a system, making it easier to identify bottlenecks, inefficiencies, and potential improvements.
Symbols Used in System Flowcharts.
System flowcharts use a standardized set of symbols to represent different elements of a system:
Process: A shape (e.g., rectangle, oval) indicating a specific action or function.
Data Input/Output: A parallelogram representing data
entering or leaving the system.
Data Storage: A cylinder or disk-shaped symbol indicating a data storage device.
Decision Point: A diamond shape representing a point where decisions are made.
Connector: A circle or diamond with a line connecting it to another part of the flowchart, indicating a logical connection.
Terminator: A rectangle with rounded corners, representing the start or end of a process.
Flow Arrows: Lines connecting symbols to indicate the direction of data flow.
Purpose of System Flowcharts.
System flowcharts serve several important purposes:
Visualizing System Processes: They provide a comprehensive overview of a system, enabling stakeholders to understand its structure and functionality.
Documenting System Requirements: Flowcharts can help define and document system requirements, ensuring that everyone has a clear understanding of what the system is supposed to accomplish.
Identifying Process Bottlenecks: Flowcharts can highlight areas of inefficiency or congestion, helping to identify potential improvements.
Planning System Enhancements: By visualizing the existing system, flowcharts can facilitate planning for enhancements and modifications.
Communicating System Design: Flowcharts provide a common language for stakeholders to discuss and understand the system, regardless of their technical background.

系统流程图。

系统流程图是系统过程、数据流和存储的图形表示。

它有助于可视化和分析信息和材料通过系统流动的方式，从而更容易识别瓶颈、低效率和潜在的改进。

系统流程图中使用的符号。

系统流程图使用一组标准化的符号来表示系统中的不同元素：
处理，表示特定操作或功能的形状（例如，矩形、椭圆形）。

数据输入/输出，表示数据进入或离开系统的平行四边形。

数据存储，表示数据存储设备的圆柱形或圆盘形符号。

决策点，表示做出决策点的菱形。

连接器，带有连接到流程图其他部分的线的一个圆圈或菱形，表示逻辑连接。

终结符，圆角矩形，表示过程的开始或结束。

流程箭头，连接符号的线，指示数据流的方向。

系统流程图的作用。

系统流程图具有以下几个重要作用：
可视化系统流程，它们提供了系统的全面概述，使利益相关者能够理解其结构和功能。

记录系统需求，流程图可以帮助定义和记录系统需求，确保每个人都清楚地了解系统应该完成什么。

识别流程瓶颈，流程图可以突出低效率或拥塞的区域，有助于识别潜在的改进。

规划系统增强，通过可视化现有系统，流程图可以促进对增强和修改的规划。

沟通系统设计，流程图提供了一种共同的语言，供利益相关者讨论和理解系统，无论其技术背景如何。
