First off all, let me introduce myself, I'am a employee in local company in Indonesia.
I'am still learning about Odoo from one month ago. I installed Odoo Community in local computer, and i pick the demo database. Now, i have put product database, and i think i have to delete the demo database. I have try to delete demo product and demo vendor, but not work.
I search in this forum with keyword "delete demo database" but it empty. I found some answer about export database and import again without demo database. But i cant found it in Odoo.
