【摘要】：随着互联网的普及,IT企业对数据统计和服务的需求也持续增加,几乎每天都有新的业务产生,这要求企业信息系统能够快速适应这样的变化。当前的IT信息系统包含了数量众多的组件,数据库组件是其中最重要的组成部分。为了保证系统的平滑升级,数据库概念模型的变更所引起的数据库组件的升级不能影响系统中其他组件的正常运行,其变更操作应该得到严格的测试。为了将这一步骤尽可能地自动化,本文从数据库信息模型定义着手,完成了一个对数据库概念模型定义及其具体物理实现进行一致性测试的系统。本文首先设计了一种基于JSON数据格式的用于规范数据库信息模型定义的表示方法,该方法对JSON数据格式附加了一定的约束,以实现对信息模型定义的统一表示。然后,结合实际的使用场景,本文实现了一个针对具体数据库模型实现进行一致性验证的数据库模型测试系统。该系统可用自动化或半自动化的方式完成对模型的数据格式、数据约束等核心要求的验证,同时可对各个信息模型符合度输出相关的信息模型验证结果。IT企业信息系统在信息模型变更和升级的过程中,可以参考本系统,以实现企业内部的信息模型定义及一致性检验的目标,减少人为因素对业务升级的影响。
[Abstract]:With the popularity of the Internet, the demand of IT enterprises for data statistics and services continues to increase, almost every day there are new business, which requires enterprise information systems to adapt to such changes quickly. The current IT information system contains a large number of components, the database component is the most important component. In order to ensure the smooth upgrade of the system, the upgrade of the database components caused by the change of the database conceptual model can not affect the normal operation of the other components in the system, and the change operation should be strictly tested. In order to automate this step as much as possible, this paper begins with the definition of database information model, and completes a consistency test system for the definition of database conceptual model and its physical implementation. This paper first designs a representation method based on JSON data format to standardize the definition of database information model. This method imposes some constraints on the JSON data format to realize the unified representation of the definition of information model. Then, combined with the actual usage scenario, this paper implements a database model testing system to verify the consistency of the specific database model implementation. The system can complete the verification of the data format, data constraints and other core requirements of the model in the way of automation or semi-automation. At the same time, it can output the relevant information model verification results to each information model conformity degree. The IT enterprise information system can refer to this system in the process of changing and upgrading the information model. In order to achieve the definition of enterprise information model and consistency inspection, reduce the impact of human factors on business upgrading.
