Whats better [Performance-wise] Filter Database or create all New Database?

I’m trying to get any advice, basically what I’m doing is displaying a week schedule with hourly time slots and a “week day” tabs [Monday, Tuesday, Wednesday, etc] . When the users clicks on the tabs, it loads the time slots for that week day. When it comes to site load performance with Wix, would it be better to load the whole database and filter/display out the day of the week’s based on users click. Or load separate databases for each week day?

I’m just trying to get your advice on best practices for performance.

Thanks
