How to add a static dataset to a LLM? Something like a database query

Lets say I have a list of properties (real estate). I want my LLM to be aware of which properties are currently on our books at any given time, however, I cant copy the entire table and paste it in as context before asking a question.

Is there an obvious way get a LLM to lookup either a static dataset via file, or ideally a database lookup?

I am using WizardLM if it helps.
