Databases in Lianja are implemented as directories containing files that correspond to the tables and associated files in the database. Operating System file protection can be applied individually to the files for added security. The directories are sub-directories of the Lianja data directory. The environment variable DB_DATADIR points to the current Lianja data directory and can be queried using the GETENV() function. Files from other directories can be added to the database using the ADD TABLE command or via the database catalog and SET AUTOCATALOG functionality. | Databases in Lianja are implemented as directories containing files that correspond to the tables and associated files in the database.

Databases in Lianja are implemented as directories containing files that correspond to the tables and associated files in the database. Operating System file protection can be applied individually to the files for added security. The directories are sub-directories of the Lianja data directory. The environment variable DB_DATADIR points to the current Lianja data directory and can be queried using the GETENV() function. Files from other directories can be added to the database using the ADD TABLE command or via the database catalog and SET AUTOCATALOG functionality.
