// to an ODBC data source. The wxDB class allows operations on the data
// source such as opening and closing the data source.
// Author: Doug Card
-// Modified by:
+// Modified by: George Tasker
+// Mods: Dec, 1998:
+// -Added support for SQL statement logging and database cataloging
+// April, 1999
+// -Added QUERY_ONLY mode support to reduce default number of cursors
+// -Added additional SQL logging code
+// -Added DEBUG-ONLY tracking of Ctable objects to detect orphaned DB connections
+// -Set ODBC option to only read committed writes to the DB so all
+// databases operate the same in that respect
