How to Use SQLite¶
As mentioned in the SWAT+ Editor Design doc, SWAT+ Editor uses uses a SQLite database to hold model input data to allow easy manipulation by the user. The database is structured to closely resemble the SWAT+ ASCII text files in order to keep a clean link between the model and editor.
