ObjectiveSQL is an ORM framework in Java based on ActiveRecord pattern, which encourages rapid development and clean, codes with the least, and convention over configuration.
- With one annotation your Class has fully featured capabilities of SQL programming
- Easy to relational(has_one, has_many and belongs_to) query and paged query
- Writing SQL expressions(arithmetic, comparison and logical) using Java syntax
- If your project focuses on data analysis based on relation database, and a lot of arithmetic expressions in SQL statement. ObjectiveSQL will help you write expressions conveniently and safely using Java syntax
- If you don’t want to write Java codes of database access and various configuration files, ObjectiveSQL's dynamic code generation will help you access the database without coding

ObjectiveSQL provides full example for various databases below, You can open it directly with IntelliJ IDEA as a standalone project. In fact, they are not just examples, but also unit tests of ObjectiveSQL in various databases.
If you want to run without configuration, you can try: SQLite
Others: MySQL, Oracle, MS SQL Server, PostgreSQL, Spring Boot
You define just a JavaBean with annotations
@DomainModel
public class Member {
private String no;
@Queryable
private String name;

private String mobile;
