The JDBC generator genrates four files to be used by programmar.
Relaxer Table Object (RTO) is a Data Access Object (DAO) to access RDBMS tables.
Relaxer Table View Object (RTVO) is a Data Access Object (DAO) to refer RDBMS tables as a table view.
Relaxer Table View Interface (RTVI) is a interface to access RDBMS tables via RTO or RTVO.
Relaxer Table List Object (RTLO) is a list interface to retrieve records in a RDBMS table.
Figure 14.1.1[Classes for Relaxer JDBC] shows relationships between these classes.
RTVI is a common interface for RTO and RTVO. RTVI defines signatures of common methods with RTO and RTVO.
RTVI, RTO, and RTVO uses RTLO to represent result data.
