如何在SQLServer中设计周期时间（营业时间）？

Question

I have such a scene like this: In my system, there are some opening time for a food store. The business scene like this:

For my food store which named 'Pet food', it will be open from Tuesday to Friday, from 11 am to 2 pm.

I want to know that how to better store these business hours.

I use the Sql Server database, and the Entity Framework core.

I found that some guys suggest using the xml data type for the business hours in Sql Server. If I do this, how do I use entity framework core to query the business hours and how display it on the html.

I want to show the open business hours in the web. When someone get into this web store, if he add a access reservation that he will visit this store. Then the system will be check his appointment time is valid

You may wish to use Entity Framework's "Value Objects" feature.

This allows you to have the SQL representation eg a number for the day of the week 1 - 7, and a SQL TIME as the opening time and SQL TIME as the closing time composed back into a single object which says the opening hours.
