Need suggestions on AI

In our company, internally they are conducting hackathon event which focus on using AI in our application. I don't have any experience in AI, but want to participate in it. Idea: Based on NLP, I want to convert to DB query, which can be used to retrieve data from our DB. Constraints: It should not expose data to web as that will be tagged as security breach. Any suggestions on where to start from and is there any open source library which can be used to achieve this use case? Reading different articles related to BERT, can this be used to achieve this?
