Making conceptual models clearer and more understandable

在开发信息系统的早期阶段，系统分析师通常创建概念模型。 这种模型主要是图解的，包括分析师可以用来描述领域的构造和规则。 例子包括实体关系模型和业务流程模型。 概念模型是至关重要的，因为它们有助于分析人员理解用户的需求，并将其传达给设计人员。 研究表明，理解用户需求是信息系统开发成功的关键。

In the early stages of developing an information system, systems analysts often create conceptual models. Such models are primarily diagrammatic, and include constructs and rules that analysts can use to describe a domain. Examples include entity-relationship models and business process models. Conceptual models are vital because they help analysts to understand users' requirements and to communicate them to designers. Research shows that understanding user requirements is the key to successful information system development.
