System: Persistence and transaction boundary
The help examples reference Informix-4GL, SQL tables such as customer, orders, items, and stock, cursor declarations, inserts, and transaction statements. This supports an Informix-related design, migration, demonstration, or source heritage. It does not establish that the running Java application connects to Informix, uses JDBC, executes these statements, or has the described transaction boundary. E0004 E0006
No database connection code, SQL execution layer, persistence implementation, or runtime integration is identified in the supplied range. The specific concurrency behavior, conflict handling, and broader integrity guarantees are likewise unresolved. E0005 E0006
Harten documentation of the Informix 4GL and Java source repository, from the retained 17 October 2026 export. The exact upstream revision analysed is not established. Source findings do not establish runtime behaviour or equivalence between the implementations.
