今天在确认实习生不能帮忙搭建数据库后,自己根据业务需求尝试搭了一个小型access数据库。 主要目的:储存历史月度数据,避免每次从公司数据库下载数据的麻烦,节省数据拉取时间。 搭建了以acct id为主键的两种数据。 1)客户信息,包括 由业务人员手工更新

今天在确认实习生不能帮忙搭建数据库后,自己根据业务需求尝试搭了一个小型access数据库。

主要目的:储存历史月度数据,避免每次从公司数据库下载数据的麻烦,节省数据拉取时间。

搭建了以acct id为主键的两种数据。

1)客户信息,包括

  由业务人员手工更新汇总的数据,如客户所在区域,商业信息等。

  由机器抓取的客户信息,如客户账号状态,专属业务人员信息等等。

上述数据按照每月定期更新,以及每周更新,存储在不同的表里。

2)客户交易信息,计划包括:

  汇总月度信息,如月成交额,交易量等;

  分多个维度的表格,如周信息,交易类型,交易来源等,该数据刷新时间段不一样,且根据业务需求,会有不同的维度需求。

另外,为了方便,把数据库里常见的“Jan-2014”细分为"Year"和"Month"两个变量,这样以后数据导入输出时,不用再费心数据格式问题,在excel里,直接用date(year,month,day)即可快速合成日期。

通过搭建多个表格,就把曾经整合在excel里的数据拆分成了多个表格,且各个表格之间刷新频率不一样,减少了我们用excel vlookup匹配的时间。

同时我新建了两个查询

1)整合客户基本信息,包括业务人员使用的信息,以及由机器抓取的信息。(这里以账户唯一识别码作为关联标识,并修改了连接属性,即所谓的左连接右连接)

2)把汇总的月度信息与客户基本信息结合起来,汇总成一张大表。该大表之后将直接导入excel中,作为数据透视表的一部分。

另外,关于操作,目前摸索出:

1)删除查询:可以删除不符合我要求的数据(如每个月导入数据时,把当前月数据删除,避免数据重复)

2)追加查询:主要用于客户交易信息,定期追加月度/季度数据。

现在需要解决的问题包括:

1)如何在导入新的账户信息后,快速找到需要追加的客户信息,并且追加(计划查找不匹配项)

2)如何在删除已经不合格的数据,以及表之间的联合,以及决定后续数据导入的工作。(相信代码可以实现,但目前还未探索)

3)关于搭建一个友好的访问界面,或者撰写文档存稿

 

总结:

access在我们数据处理初期并不常用。但是随着数据量的扩大,我们自然而然的要用到多个数据库。

从access起步,个人觉得还比较容易。

以及,积极主动,代表着,要努力学习。之前把这个任务分配给实习生时,没有得到满意答复,但是自己折腾,在熟知业务的基础上,也勉强能完成一个符合大致需求的数据库。未来还需要多加尝试,并规范化模板。

再以及,比一年前为了某个TEAM搭建CRM系统时对ACCESS的一窍不通,这一次经过多番思考,很顺利就完成了框架的搭建,表扬自己一个!\(^o^)/~

How does the Java reflection mechanism modify the behavior of a class? How does the Java reflection mechanism modify the behavior of a class? May 03, 2024 pm 06:15 PM

The Java reflection mechanism allows programs to dynamically modify the behavior of classes without modifying the source code. By operating the Class object, you can create instances through newInstance(), modify private field values, call private methods, etc. Reflection should be used with caution, however, as it can cause unexpected behavior and security issues, and has a performance overhead.

How to use Fail2Ban to protect your server from brute force attacks How to use Fail2Ban to protect your server from brute force attacks Apr 27, 2024 am 08:34 AM

An important task for Linux administrators is to protect the server from illegal attacks or access. By default, Linux systems come with well-configured firewalls, such as iptables, Uncomplicated Firewall (UFW), ConfigServerSecurityFirewall (CSF), etc., which can prevent a variety of attacks. Any machine connected to the Internet is a potential target for malicious attacks. There is a tool called Fail2Ban that can be used to mitigate illegal access on the server. What is Fail2Ban? Fail2Ban[1] is an intrusion prevention software that protects servers from brute force attacks. It is written in Python programming language
