Ionic2 framework app work offline and syncing data with Oracle

I am developing an app in ionic2 framework and i want to use Oracle as database. I want to work my app on offline and sync the data to my database. I find PouchDB which works as a local storage and sync with CouchDB. But I also find, there is no way to sync PouchDB with Oracle. Is there any other local storage which work offline and sync with Oracle?
