很多小伙伴纠结于这个一百天的时间,我觉得完全没有必要,也违背了我最初放这个大纲上来的初衷,我是觉得这个学习大纲还不错,自学按照这个来也能相对系统的学习知识,而不是零散细碎的知识最后无法整合,每个人的基础以及学习进度都不一样,没有必要纠结于一百天这个时间,甭管你是用三个月还是用一年来学习这些东西,最后学到了不就是收获吗?何必纠结于这一百天,觉得这一百天学习不完我就放弃了呢?(另,项目后面没有更新完,大家可以按照这个框架去学习,没有更新完的大家可以自行找资料.) PS:很多人在学习Python的过程…

Atitit 数据存储视图的最佳实际best practice attilax总结 1.1. 视图优点:可读性的提升1 1.2. 结论  本着可读性优先于性能的原则,面向人类编程优先于面向机器编程,应该优先使用视图2 1.3. 视图的缺点:复杂视图有时可能带来性能下降3 1.1. 视图优点:可读性的提升 视图的主要作用有以下几点:视点集中:使用户只关心它感兴趣的某些特定数据和他们所负责的特定任务简化操作:,若视图本身就是一个复杂查询的结果集,这样在每一次执行相同的查询时,不必重新写这些复杂的查询…

什么是模型 模型是对现实的简化 模型是提供系统的蓝图,模型可是包括详细计划.也可是是从更高程度考虑系统的总体计划,每个系统可以从不同的方面用不通过的模型来描述.因而每个模型都是在语义上闭合的抽象系统.模型可以是结构性的,强调系统的组织.也可是是行为性的,强调系统的动态方面 举例:售楼中心里面的楼盘蓝图 为什么建模 建模是为了能够更好地理解正在开发的系统 通过建模达到下面的目的1.模型有助于按照实际情况或按照所需的样式对系统进行可视化2.模型能够规约系统的结构或行为3.模型给出了构造系统的模板4.…
