-// INFO:
-// all record items/columns may be defined in one table (1.), or
-// they can be splitted in two separate tables (2.) (eg. for FTS support)
-// 1.) you have to define "static QString const sTableName"
-// 2.) you have to define two table names:
-//     "static QString const sTable1Name"
-//     "static QString const sTable2Name"
-// and since all record items/columns are handled by one QSqlRecord,
-// you have to also define number of columns that belongs to table 1 (1.), and table 2 (2.)
-// 1.) "static int const sTable1ColCount"
-// 2.) "static int const sTable2ColCount"
-// there are also defined auxiliary methods for 1-Table/2-Tables approach, see bellow
