## What it is
jOOQ is a Java library that models SQL as a type-safe internal DSL, with a source code generator that reverse-engineers your database schema into Java classes. It provides fluent query building, dialect abstraction across 30+ RDBMS, DAOs, active records, SQL parsing/translation, and reactive support via R2DBC.

## Use cases
- write type-safe SQL queries in Java
- generate Java classes from database schema
- replace JDBC boilerplate for database access
- translate SQL between different database dialects
- build dynamic SQL queries with a fluent API
- map query results to POJOs and DAOs
- migrate from Hibernate/JPA to a SQL-centric approach

## When to choose
- you want SQL-first development where the database schema drives your Java code
- you need compile-time safety for SQL queries against your schema
- you must support multiple SQL dialects from one codebase
- you find ORMs like Hibernate too opaque and want explicit SQL control

## When to avoid
- you want a pure object-relational mapping with entity persistence and change tracking
- your project is not on the JVM
- you need a fully free license for commercial databases like Oracle or SQL Server (commercial editions required)
- you prefer schema-less or NoSQL data access

## Facets
