+  { Database Journalling.
-+
-+
+    This class is intended to support a client side journal of all database
-+
+    updates, inserts and deletes made by the client during a session. It also records
-+
+    the transaction each update was made under.
-+
-+
+    The database schema is required to include a control table "IBX$JOURNALS" and
-+
+    an SQL Sequence IBX$SESSIONS. These are created by the class when the
-+
+    database is opened, if they are not already present. However, it is recommended
-+
+    that they are created as an orginal part of the database schema in order to
-+
+    unnecessarily avoid each user being given sufficient priviledge to create tables
-+
+    and Sequences.
-+
-+
+    Syntax:
-+
-+
+    Transaction Start:
-+
+    *S:<date/time>,<attachmentid>,<session id>,<transaction no.>,<string length>:<transaction Name>,<string length>:<TPB>,<default Completion>
-+
-+
+    Transaction Commit:
-+
+    *C:<date/time>,<attachmentid>,<session id>,<transaction no.>
-+
-+
+    Transaction Commit retaining :
-+
+    *c:<date/time>,<attachmentid>,<session id>,<transaction no.><old transaction no.>
-+
-+
+    Transaction Rollback:
-+
+    *R:<date/time>,<attachmentid>,<session id>,<transaction no.>
-+
-+
+    Transaction Rollback retaining:
-+
+    *r:<date/time>,<attachmentid>,<session id>,<transaction no.><old transaction no.>
-+
-+
+    Update/Insert/Delete
-+
