BeetlSQL的目标是提供高效的数据库访问框架，无论要连接何种数据库，提供一致的编写代码方式。 截止到M3,目前支持数据有
- 传统数据库：MySQL,MariaDB,Oralce,Postgres,DB2,SQL Server，H2,SQLite,神通，达梦等
- 大数据：HBase，ClickHouse，Cassandar，Hive
- 物联网时序数据库：Machbase
- SQL查询引擎:Drill,Presto
在M4阶段的目标还包括Elastic Search,Derby,SQLite,松果时序库，TD engine时序库,Druid，北大金仓,Neo4J

- ComplexMapping 表示复杂映射，这里是左连接一对多关系
- ExecuteJdbc是直接执行JDBC并将结果映射到POJO
- ExecuteTemplate 是直接执行模板语句（或者HQL），并将结果映射到POJO
- File，SQL语句保存在专有文件里
- Insert，内置新增语句
- One2Many 通过注解实现一对多查询
- PageQuery 翻页语句查询，并返回一个PageResult
- SelectById 根据主键查询POJO
- LambdaQuery 构造查询的SQL语句，且支持重构
