一种基于数据访问流的数据库索引优化方法该方法通过集成业务流程模型与数据模型,抽取了流程活动中包含的数据访问操作和流程的控制结构形成数据访问流,分析了数据访问流中数据访问操作的频度,为频繁数据访问操作所对应的数据项创建索引,达到改善数据访问性能的目的。实验结果表明,该方法提高了数据查询的速度。-A novel method called data-access-flow based index optimization (DAFIO) is proposed to provide automatic index select for databasein order to improve the data access performance. By integrating the data model and process model of the IT systems and getting data access flow, theDAFIO method can analyze the data access flow to find those data item which are accessed frequently, and then create indexes for these frequentitems. The experiment results show that the novel method is effective to improve the data access performance.

v2.82 build1114版
1、增加了Excel名单文件上传、导入功能
2、为了正确指定文件上传目录,各文件夹名中不许有字符“.”,故将原命名方式“School V2.82 Build1114”改为“School V282 Build1114”。
-completely kernel, interface changes, the increase in student enrollment statistics, faculty, classes such as a management function. Add two individual achievements. Batch added three results. Search through deletion and modification In addition to four. directly alter five. Batch 6 can be deleted. GO can reach you directly to the arrival of page 7 . Pagination 8. 9 streamlined code. Integration of duplicate code v2.82 build111 4 version of an increased list of Excel file uploads into two functions. , Therefore, the original name means "School V2.82 Build1114" to "School V2 82 Build1114. "
