Database and persistence

System: Database and persistence

The main module selects a database alias named stores7, and customer and order sources use Java SQL classes, prepared statements, result sets, and record wrappers. SQL references include customer, orders, items, stock, manufact, and state tables. These facts support a database-oriented implementation, but the actual stores7 schema and the framework’s connection behavior are not included. E0001 E0002

The help and source artifacts contain Informix-4GL terminology and examples, supporting an inference that the Java artifacts derive from, wrap, or coexist with an Informix-4GL-oriented system. The supplied range does not establish the translation pipeline, runtime relationship, or whether every documented relational example corresponds to executable Java behavior. E0003 E0004
