architecture 1. Keep a design easy to change - > Separate external input/output and business logic 2. Reach common understanding of implementation policies in a team • -> To make readable and need server-side architecture 1. Keep a design easy to change We are not able to achieve business logic "common understanding" ### 2. Common understanding of implementation policies in a team ## • Refer to Layered Architecture • Apply DIP (Dependency Inversion Principle) to isolate domain logic from infrastructure implementations(ex. database handling) ## Example of my team ## Go Skills/Knowledge

pipelines, for example, fit this model perfectly. Although Go's approach to concurrency originates in Hoare's Communicating Sequential Processes (CSP), it can also be seen as a type-safe generalization Pascal/Modula/Oberon family (declarations, packages), plus some ideas from languages inspired by Tony Hoare's CSP, such as Newsqueak and Limbo (concurrency). However, it is a new language across the board the most successful models for providing high-level linguistic support for concurrency comes from Hoare's Communicating Sequential Processes, or CSP. Occam and Erlang are two well known languages that

TupleSort 排序在Greenplum中的应用 ## 内排序算法 冒泡排序 • 插入排序 • 快速排序 • 堆排序 • 基数排序 ## 快速排序 快速排序是最常用的排序算法，由Tony Hoare在1959年发明。 快速排序算法的三个步骤： 挑选基准值: 从数列中挑选出一个基准元素, 称为pivot 分割: 重新排序数组, 所有比基准元素小的元素排放到基准元素之前; 所有比基准元素大的元素排放到基准元素之后。分割完成后
