A word on the default implementation

The BookkeepingSvc class is a service that implements all Editor interfaces and as a consequence all Info interfaces. The details of the implementation won't be described here but some facts need to be known :

• All connections to the database are using JDBC. The only requirement is to give correct connection string, user name and password when creating the service. An example of an initialization string is : ''jdbc:oracle:thin:@oradev:10521:D''
• Every query done on the bookkeeping database corresponds to a SQL statement. The whole list of statements used was put at the very beginning of the Java file.
• The rest of the code is made of very simple calls to JDBC.
