Answer
Manually map each column of a ResultSet to a field in a Java object.
Manual ORM involves extracting each column value from a ResultSet and setting it into a corresponding field in a Java object. This requires knowing the structure of both the ResultSet and the target object. For example, mapping a 'Product' class with fields like id, name, and price involves using rs.getInt(), rs.getString(), and rs.getDouble() to populate the Product object's fields.
