A database schema consists of main data tables and lookup tables (validation tables). We want to identify them by name convention as well. The reason is data table contains more fields and needs 'design' while lookup table has simple and almost unified structure. For instance, if we name main data tables using 'sis_survey', then we may name lookup table using 'sis_vt_surveytype.
