> Pre-built App subclasses for common extraction patterns—start from a template instead of from scratch.

Templates are pre-built `App` subclasses that implement common extraction patterns. Instead of writing orchestration logic, SQL queries, and task wiring from scratch, you subclass a template and override only the parts that are specific to your data source.

Everything the template provides—task structure, retry configuration, output contracts, and orchestration order—is inherited automatically. Override what you need; get the rest for free.

 Extract databases, schemas, tables, columns, views, and procedures from any SQL source using `SqlApp`.
