数据统计是每一个体系中必备的功用，在给指导报告统计数据，工作中须要的希望数据时异常有效。
在我看来，一个统计的模块应当完成以下功用：
可以将经常运用的查询的统计效果显现出来；
显现的效果可所以表格情势，也可所以图形情势，如果是图形的话可以以多种情势显现（柱状图、折线图、饼图、雷达图、堆叠柱状图等）：
统计查询的效果，点击数字或许百分比可以显现细致的数据；
可以自由组合查询前提、挑选前提、分组前提、排序等；
统计效果最好有个及时预览；
查询统计可以保留，以便下次能直接挪用并显现统计查询的效果；
关于保留后的查询统计，下次挪用时也可以根据天真的挑选手腕对查询效果举行挑选；
界面须要做的简约、直观，就算是不太懂电脑的操作员也可以轻易运用；
关于一些庞杂的查询，可以直接在背景写Sql或许挪用Sp出数据
......
好了，以下是在现实环境中的完成和运用：
这是一个门生的就业体系，门生在差别的时代会对本身毕业去处举行登记，因而根据差别时候截点统计出来的数据是不一样的。数据表有100多个字段（并非一切字段都须要统计）。
起首，我们在数据库中构建一个表值函数，可以根据差别的时候截点返回出数据，表也起到视图的作用，将参数表的值直接包含到返回效果中去。

如许我们运用 select * from [get...]('2016-8-25') 就可以查询出8月25日停止日期的数据。
接下来是界面设计，我们运用jequery-ui中dropable\dragable的控件，字段分列在界面上，直接拖拽到响应域里，就可以举行统计。
除了分组字段外，显现字段还可以根据详细的值举行统计过滤，起到多重分组统计的功用。
人人可以看到，最上面一栏是数据挑选，然后是体系已保留的查询（分为表格查询和图形查询），点击保留好的查询直接出查询效果，也可以删除保留的查询。在下面是自定义查询，上面是一排前提，然后是可以拖拽的字段，当字段拖至分组列，则显现字段称号；拖至显现列，还可以对显现的数据的详细值举行分组挑选统计。下方则是一些选项，是不是显现小计、算计，以何种体式格局显现图表。
以表格情势的显现统计，可以看到，每一个数值都可以点击弹出框显现概况，最下方可以保留查询前提，以图形体式格局显现等：

估计今后版本须要制造的功用：
对统计字段举行进一步优化，可以运用多个前提组合挑选同一个字段，这个比较简单，扩大下类而且UI调解下就可以了。
以上就是运用Asp.net完成信息管理体系的数据统计功用的细致内容，更多请关注ki4网别的相干文章！
