本考题考查的知识点为版本管理基础知识。
(1)处于“草稿”状态的配置项的版本号格式为:0.YZ。
YZ数字范围为01-99。
随着草稿的不断完善,“YZ”的取值应递增。“YZ”的初值和增幅由开发者自己把握。
(2)处于“正式发布”状态的配置项的版本号格式为:X.Y
X为主版本号,取值范围为1~9,Y为次版本号,取值范围为1~9。
配置项第一次“正式发布”时,版本号为1.0。
如果配置项的版本升级幅度比较小,一般只增大Y值,X值保持不变。只有当配置项版本升级幅度比较大时,才允许增大X值。
(3)处于“正在修改”状态的配置项的版本号格式为:X.YZ
配置项正在修改时,一般只增大Z值,X.Y值保持不变。
当配置项修改完毕,状态重新成为“正式发布”时,将Z值设置为0,增加X.Y值。
