首先想说明使用C# 来开发Web 版的CMDB是个人的原始需求, 并没有领导或者公司内部有专门的项目支持我做这个事情, 但是考虑到自己的兴趣和职业发展, 自己向自己提了一个需求 ---搭建一个Web CMDB

之前也有了解过市场上有很多开源的CMDB 和付费的CMDB 产品, 但是总之一句话, 系统是别人的, 不能把公司实际的业务需求100%都涵盖了, 或者说不想使用多余(个人认为)的功能

所以有了总的目标之后一系列的小目标或者分支需求, 接二连三的自己给自己提了一大堆, 一边提需求一边自己从网上找一些资料, 消化吸收, 再在我的环境当中反复验证, 反复找网上的视频和其他文章

下面就简单整理了开发Web CMDB 已经储备了一些需要的基础知识

  1. HTML 基础知识
  2. JavaScript, Jquery, Ajax
  3. C#, MVC基础知识
  4. LDAP 基础
