56 +  { Database Journalling.
57 +
58 +    This class is intended to support a client side journal of all database
59 +    updates, inserts and deletes made by the client during a session. It also records
60 +    the transaction each update was made under.
61 +
62 +    The database schema is required to include a control table "IBX$JOURNALS" and
63 +    an SQL Sequence IBX$SESSIONS. These are created by the class when the
64 +    database is opened, if they are not already present. However, it is recommended
65 +    that they are created as an orginal part of the database schema in order to
66 +    unnecessarily avoid each user being given sufficient priviledge to create tables
67 +    and Sequences.
68 +
69 +    Syntax:
70 +
71 +    Transaction Start:
72 +    *S:<date/time>,<session id>,<transaction no.>,<string length>:<transaction Name>,<string length>:<TPB>,<default Completion>
73 +
74 +    Transaction Commit:
75 +    *C:<date/time>,<session id>,<transaction no.>
76 +
77 +    Transaction Commit retaining :
78 +    *c:<date/time>,<session id>,<transaction no.><old transaction no.>
79 +
80 +    Transaction Rollback:
81 +    *R:<date/time>,<session id>,<transaction no.>
82 +
83 +    Transaction Rollback retaining:
84 +    *r:<date/time>,<session id>,<transaction no.><old transaction no.>
85 +
86 +    Update/Insert/Delete
87 +    *Q:<date/time>,<session id>,<transaction no.>,<length of query text in bytes>:<query text>
