JOOQ and Flyway
The document provides an overview of using Flyway and JOOQ together to manage database migrations and generate Java objects from database schemas. Flyway is used to run SQL scripts for schema migrations, while JOOQ generates Java classes that correspond to database tables and can be used to write type-safe SQL queries. Examples are given of using JOOQ to build queries, fetch results in various formats, perform CRUD operations on records, and integrate Flyway and JOOQ into build systems like Gradle.
