🔰 简介

Derd是一个基于.net core开发的跨平台轻量级数据库操作框架。Derd模型定义文件基于XML文件格式，模型管理基于目录自动分类；数据库类型支持Sqlite、MySql、Oracle、Sqlserver、Postgresql、达梦、人大金仓等，数据库配置文件和模型定义一样基于目录划分，并支持基于目录层级的继承能力；数据操作采用链式方式，简单易用。

特点列表：
  • XML格式定义模型
  • JSON格式属性，像使用对象一样使用JSON
  • 索引约束定义，普通索引、主键索引、组合索引...
  • 关联外键定义，支持模型级深度关联
  • 数据库事务支持，
  • 查询方法支持链式操作，代码易写、易读、易维护
  • 属性值格式约束定义&校验，模型定义同时搞定表单逻辑
  • 属性值保存前自定义加工，支持动态函数处理器
  • 属性值查询后自定义处理，支持动态函数处理器
  • 模型增、删、改前后自定义拦截事件，轻松处理复杂逻辑
  • 新建数据保存时属性是否参与保存可设置
  • 更新数据保存时属性是否参与保存可设置
  • 默认值设置支持自定义，支持动态函数处理器
  • 查询返回dynamic动态对象，默认关联模型定义属性

📦安装

Package Manager
Install-Package Derd -Version 2.8.1
.NET CLI
dotnet add package Derd --version 2.8.1
PackageReference
<PackageReference Include="Derd" Version="2.8.1" />
Paket CLI
paket add Derd --version 2.8.1

🛠️使用说明

Derd基于微软的DbProviderFactory技术实现，根据实际使用的数据库类型，需要引入实现了对应数据库的DbProviderFactory相关接口的第三方包；已测试并验证通过的数据库第三方包对应关系如下：

数据库库类型 依赖包
Sqlite System.Data.SQLite
Mysql MySql.Data
Oracle Oracle.ManagedDataAccess.Core
SqlServer Microsoft.Data.SqlClient
Postgres Npgsql
达梦 dmdbms.DmProvider
人大金仓 Kdbndp

使用时，可根据需要添加其中的一项或多项依赖。

*注：其他未列出的实现了微软DbProviderFactory接口的数据库理论上应全部支持，尚未实际验证；有兴趣的小伙伴可自己试验。
