The schema of every UltraLite database is described in several system tables. Because UltraLite does not support table ownership, these system tables are accessible to any UltraLite user.
The contents of system tables can be changed only by UltraLite itself. UPDATE, DELETE, and INSERT commands cannot be used to modify the contents of these tables. Furthermore, the structure of these tables cannot be changed using the ALTER TABLE and DROP statements.
