十幾隻app每隻幾十個table再各自call唔同internal external api再出service俾其他app 淨係得兩個fg做好難想像會有公司將成個System嘅Deisgn畀一個Programmer,除非你講緊嘅System係十幾個Table嘅CRUD,Table之間又冇咩關係。係有一致嘅定義,但啲人鍾意濫用。現實係一入職已經要由design whole system到coding都一腳踢
P - code module and design the program.
AP - design a few modules and their relationship.
SA - design the whole system and relationships between all of the modules.
但係System規模有大有細,大System一定複雜過細system,相當嘅難度要有相應嘅實力。
唔好以為細公司先係咁
有幾百隻IT狗嘅大企都係咁
