ActiveJDBC

ActiveJDBC is a Java implementation of the Active Record design pattern developed by Igor Polevoy. It was inspired by ActiveRecord ORM from Ruby on Rails. It is based on convention over configuration.
Writing models
Similar to Ruby on Rails, the ActiveJDBC infers meta data from a database. The result is that models do not require setters and getters.
Example
Creating and updating records
Creation of and saving new records in a table:
<syntaxhighlight lang="java">
Employee e = new Employee();
e.set("first_name", "John");
e.set("last_name", "Doe");
e.saveIt();
</syntaxhighlight>
or the same on one line:
<syntaxhighlight lang="java">
Employee.createIt("first_name", "John", "last_name", "Doe");
</syntaxhighlight>
And for updating an existing record:
<syntaxhighlight lang="java">
Employee e Employee.findFirst("first_name ?", "John");
e.set("last_name", "Steinbeck").saveIt();
</syntaxhighlight>
Finding records
ActiveJDBC does not have a query language. Search criteria are written in abbreviated SQL.
<syntaxhighlight lang="java">
List<Employee> employees Employee.where("first_name ?", "John");
</syntaxhighlight>
