信息管理系统开发中的数据开发(中文3200字,英文1700字)
在许多组织中，数据库开发从企业数据建模开始，它建立了组织数据库的范围和基本内容。这具有代表性的一步发生在信息系统计划期间。它的目的是为了创造一个组织数据的整体景象或解释，而不是为了一个特殊数据库的设计。一个特殊数据库为一个或更多信息系统提供数据，然而一个企业数据模型，也许包含了许多数据库，描述了由组织维护的数据范围。在回顾当前系统的企业数据模型中，分析须被支持的商业区的性质，描述在一个高度抽象下的数据需求，并且计划一个或更多数据库开发规划。

Data Development Within Information Management System Development
In many organizations, database development begins with enterprise data modeling, which establishes the range and general contents of organizational databases. This step typically occurs during information systems planning for an organization. Its purpose is to create an overall picture or explanation of organizational data, not the design for a particular database. A particular database provides the data for one or more information systems, whereas an enterprise data model, which may encompass many databases, describes the scope of data maintained by the organization. In enterprise data modeling you review current systems, analyze the nature of the business areas to be supported, describe the data needed at a very high level of abstraction, and plan one or more database development projects.
