Backend DevelopmentC#.Net TutorialUsing Asp.net to implement data statistics function of information management system
This article mainly introduces the implementation method of data statistics function in Asp.net management information system. Friends who need it can refer to it
Data statistics is an essential function in every system. It is for leaders Very useful when reporting statistics and progress data needed for work.
In my opinion, a statistical module should implement the following functions:
Be able to display the statistical results of commonly used queries;
The displayed results can be in tabular form or graphic form. If it is graphic, it can be displayed in multiple forms (bar chart, line chart, pie chart, radar chart, stacked bar chart, etc.):
Statistical query results, click on the number or percentage to display detailed data;
You can freely combine query conditions, filter conditions, grouping conditions, and sorting etc.;
It is best to have a real-time preview of statistical results;
The query statistics can be saved so that the statistical query can be directly called and displayed next time The results;
For the saved query statistics, the query results can also be filtered according to the flexible filtering method the next time it is called;
The interface needs to be simple and intuitive, so that even operators who don’t know much about computers can use it easily;
For some complex queries, you can directly write Sql in the background or call Sp Out of data
......
Okay, the following is the implementation and application in the actual environment:
This is a student In the employment system, students will register their graduation destination at different periods, so the statistics based on different time cutoffs are different. The data table has more than 100 fields (not all fields require statistics).
First, we build a table-valued function in the database that can return data according to different time cutoffs. The table also serves as a view, and the value of the parameter table is directly included in the return result.
ALTER FUNCTION [dbo].[Get.............] ( @gxsj datetime ) RETURNS TABLE AS RETURN ( select t1.*, dbo.depacode.xymc, CASE t1.xldm WHEN '01' THEN '博士' WHEN '11' THEN '硕士' WHEN '25' THEN '双学位' WHEN '31' THEN '本科' WHEN '41' THEN '专科' WHEN '61' THEN '高职' ELSE '' END AS xlmc, CASE WHEN LEFT(t1.sydqdm, 2) IN ('11', '12', '13', '21', '31', '32', '33', '35', '37', '44', '46', '71', '81', '82') THEN '东部' WHEN LEFT(t1.sydqdm, 2) IN ('14', '22', '23', '34', '36', '41', '42', '43') THEN '中部' WHEN LEFT(t1.sydqdm, 2) IN ('15', '45', '51', '50', '52', '53', '54', '61', '62', '65', '63', '64') THEN '西部' ELSE '' END AS sydq, sydq.dwdqmc AS sysf, CASE WHEN LEFT(t1.dwdqdm, 2) IN ('11', '12', '13', '21', '31', '32', '33', '35', '37', '44', '46', '71', '81', '82') THEN '东部' WHEN LEFT(t1.dwdqdm, 2) IN ('14', '22', '23', '34', '36', '41', '42', '43') THEN '中部' WHEN LEFT(t1.dwdqdm, 2) IN ('15', '45', '51', '50', '52', '53', '54', '61', '62', '65', '63', '64') THEN '西部' ELSE '' END AS dwdq, dwdq.dwdqmc AS dwsf, dbo.Entcode.hyname, dbo.hydygx.hymldm, dbo.hydygx.hyml, CASE t1.xbdm WHEN 1 THEN '男' WHEN 2 THEN '女' ELSE '男' END AS xbmc, [mzdmb].[nation] AS mzmc, [EjByqxdmb].[Ejbyqxmc], dbo.byqxdygx.jybbyqx, t1.gn500 AS jybdwxzdm, CASE t1.knslbdm WHEN '7' THEN '就业困难、家庭困难和残疾' WHEN '6' THEN '家庭困难和残疾' WHEN '5' THEN '就业困难和残疾' WHEN '4' THEN '残疾' WHEN '3' THEN '就业和家庭困难' WHEN '2' THEN '家庭困难' WHEN '1' THEN '就业困难' ELSE '非困难生' END AS Knslb from [table] as t1 LEFT OUTER JOIN dbo.depacode ON t1.xydm = dbo.depacode.xydm LEFT OUTER JOIN dbo.dwdq AS sydq ON LEFT(t1.sydqdm, 2) + '0000' = sydq.dwdqdm LEFT OUTER JOIN dbo.dwdq AS dwdq ON LEFT(t1.dwdqdm, 2) + '0000' = dwdq.dwdqdm LEFT OUTER JOIN dbo.Entcode ON t1.hylb = dbo.Entcode.hycode LEFT OUTER JOIN dbo.hydygx ON t1.hylb = dbo.hydygx.hydldm LEFT OUTER JOIN [mzdmb] ON t1.mzdm = [mzdmb].[mzdm] LEFT OUTER JOIN [EjByqxdmb] ON t1.byqx2 = [EjByqxdmb].[Ejbyqxdm] LEFT OUTER JOIN dbo.byqxdygx ON t1.byqx = dbo.byqxdygx.shbyqx AND t1.dwxzdm = dbo.byqxdygx.shdwxzdm where [gxsj] <= dateadd(day,1,@gxsj) and HisId in (SELECT TOP 1 HisId FROM [table] WHERE [gxsj] <= dateadd(day,1,@gxsj) and xsxh = t1.xsxh and bynf = t1.bynf and t1.byqx not in ('08','05','11') ORDER BY [gxsj] DESC) )
In this way, we can use select * from [get...]('2016-8-25') to query August 25 Data as of date.
The next step is the interface design. We use the dropable\dragable controls in jquery-ui. The fields are arranged on the interface and can be directly dragged into the corresponding fields to perform statistics.
In addition to the grouping fields, the display fields can also perform statistical filtering based on specific values, serving the function of multiple grouping statistics.
As you can see, the top column is data filtering, and then there are queries that have been saved by the system (divided into table queries and Graphical query), click the saved query to directly display the query results, or delete the saved query. Below is a custom query, above is a row of conditions, and then fields that can be dragged and dropped. When a field is dragged to the grouping column, the field name is displayed; by dragging to the display column, the specific values of the displayed data can also be grouped and filtered. statistics. Below are some options, whether to display subtotals and totals, and how to display the chart.
Display statistics in tabular form. You can see that each value can be clicked on the pop-up box to display details. At the bottom, query conditions can be saved and displayed graphically:
Graphic display:

It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
