Welcome to Doma 2¶
Doma 2 is a database access framework for Java 8+. Doma has various strengths:
- Verifies and generates source code at compile time using annotation processing.
- Maps database columns to user-defined Java objects.
- Uses SQL templates, called “two-way SQL”.
- Supports classes introduced in Java 8, such as
java.time.LocalDate,java.util.Optional, andjava.util.stream.Stream. - Has no dependence on other libraries.
