# THU-RDBMS
一个单用户的、基于 C++ 的数据库系统，是清华大学计算机系大三上课程**数据库系统概论**的大作业。
## 应该实现的功能
### DDL
* CREATE DATABASE
* CREATE TABLE
* USE
* SHOW DATABASES/SHOW TABLES
* DESC
FOREIGN KEY REFERENCE 到复合的主键上的情况不考虑。
#### CREATE TABLE 数据类型
* INT
* FLOAT
* CHAR
* DATE
* VARCHAR
#### CREATE TABLE 约束
* PRIMARY KEY
* 实体完整性约束
* FOREIGN KEY (部分)
* 参照完整性约束
* NOT NULL
### DML
* INSERT
* SELECT
* DELETE
* UPDATE
注意这部分有诸多功能都**不**需要实现，例如：
* SELECT 嵌套：不用实现
* DISTINCT：不用实现
* ORDER BY：不用实现
* GROUP BY：不用实现
* 聚集函数：不用实现
