使用递归的方法实现的算式分析器，给定一个符合C语言格式的算式，可以使用括号，单目运算符等，计算算式的运算结果。-use recursive method formula Analyzer, to set a C-language format with the formula, you can use brackets, Monocular Operators, calculation formula of the calculation results.

能够输入节点 然后完成图的广度优先遍历-Able to enter the node and then complete the graph breadth-first traversal

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.
