Topics follow a teaching order. Each answer ends with a clear Next question control so you can move forward without hunting the list.
JDBC (fresher level) introduces database access in Java. This module is an elevation arc: it opens with JDBC overview (what it is, the driver model), then the connection and statement types (Statement vs PreparedStatement — the security distinction). Result sets and connection pooling follow at the mechanics tier, then SQL injection (the vulnerability PreparedStatement prevents). It closes with JDBC vs JPA — the comparison that explains why JPA exists.
