做了很多数据库表的设计，发现了一些共性。很多字段几乎必备的。对于实体来说，比如用户、角色、分组等，一般都有ID、Name、Description等。具体一点，常见的字段有以下几个：必备字段 ID 主键，唯一ID Name，名字 Description，备注常见字段 Alias,昵

做了很多数据库表的设计，发现了一些共性。

很多字段几乎必备的。

对于实体来说，比如用户、角色、分组等，一般都有ID、Name、Description等。

具体一点，常见的字段有以下几个：

必备字段

ID 主键，唯一ID

Name，名字

Description，备注

常见字段

Alias,昵称，别名

Status，实体的状态，比如正常、冻结

Category,类别，比如用户属于哪个组，角色是哪个，媒体的分类

联系方式字段

对于用户、公司、组织机构等，一般会有联系方式这个字段。

Mobile：手机号

Email：邮件

QQ：QQ号码，现在很多系统都允许填写QQ号了，QQ已经主键成为“行业标准”

Tel：固话

Fax：传真

7个标准字段

CreateUser:创建人

CreateTime:创建时间

UpdateUser:更新人

UpdateTime:更新时间

DeleteUser:删除人

DeleteTime:删除时间

IsDeleted:是否已经删除

数据库系统设计的共性

以上是数据库表设计的共性，如果针对整个数据库来说，也是存在共性的。

对于整个数据库系统设计来说，一般都会有用户管理和操作日志这个模块，有的系统会带有权限管理。

因此，构建一套标准的模块化的用户、日志、权限组件还是有必要的。

用户

User：ID,Name,Description，Email等

日志

OpLog：ID，UserId，OpType，OpObject，Time

操作人、操作对象、操作类型等

权限

角色、权限等。

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
