- IWStatement: In this class all queries which pertaining to the application layer such as update, delete, insert commands etc.
- IWResult: After all execution this class gives output to the application layer.
Application Layer: It is very important layer on which all operations performs all types of source, word and domain etc. It is also contain some classes:
- IWsynset: It represents Synset.
- IWAPIClass: In this class initialization of library starts, and also maintain some tables and connectivity to database.
- IWSynsetCollection: It gather all synsets.
- IWWord: Word represent.
