How do Oracle Forms migrated with ORMIT™-OpenJava access the database?

Only through the back end: the browser never connects to the database. Each block gets a generated data model, and record groups can also run SQL built from the request's parameters.

• Java back end: connects with JDBC and pooled connections (Apache Commons DBCP2). It uses RENAPS' own data-access layer instead of JPA or Hibernate, so 100% of the original SQL queries can be migrated.
• 100% Node.js back end: uses TypeORM.
