具有简单类型的公共变量的本地表与类 [英] Local Table vs. Class for Public Variables with simple types

问题描述

我有一个问题基于：

http://groups.google.com/group/comp....2bbc027bf00720


一个本地表可以作为一个穷人的公共存储库，用于简单的''类型的公共

变量。'

的相对优点是什么？创建一个类或集合而不是使用本地表？

解决方案

< blockquote>我不是真的回答你的问题（aplogies）但

我使用了数据库的自定义属性或访问> = 2000 of

当前项目。

优点：

1.它们在打开应用程序时仍然可用（即

我们可以保存用户的偏好）;

2.属于前端所以没有担心差别化

来自Jean''的John''s。

本地表具有相同的优点。自定义属性是否具有

的优势，本地桌子没有这个优势？


James A. Fortune

主要是持久性。


如果你只是坚持静态值，那么你无关紧要

使用。


我坚持用户可以更改的值（即用户

设置）然后你需要坚持到可以做的事情写给。

典型的例子包括： -

数据表

Ini文件

纯文本文件
注册表（特别是使用GetSetting / SaveSetting）

数据库属性

I have a question based somewhat on:

http://groups.google.com/group/comp....2bbc027bf00720

A local table works well as a poor-man''s repository for public
variables with simple ''Types.'' What are the relative merits of
creating a class or collection versus using a local table?

James A. Fortune

解决方案

I''m not really answering your question (aplogies) but
I have used custom properties of the database or in access >=2000 of
the current project.
Advantages:
1. They persist and are available on opening the application (that is
we can save a user''s preferences) ;
2. The belong to the front end so not worry about differentiatings
John''s from Jean''s.

A local table has the same advantages. Do the custom properties have
an advantage that is not shared by a local table?

James A. Fortune

The main thing is persistence.

If you are simply persisting static values then it doesn''t matter what you
use.

I you are persisting values which can be altered by the user (i.e. user
settings) then you need to persist to something which can be written to.
Typical examples include:-
Data tables
Ini Files
Plain text files
Registry (especially using GetSetting/SaveSetting)
Database properties
