Question

I am using the code first approach and want to create a table called Classes. This table will hold the following information:

• Name (Math 1)
• Code (MatA)
• Subject (Mathmatics)
• Description (Math is fun)
• BeginTime (DateTime)
• EndTime (DateTime)
• BeginDate (DateTime)
• EndDate (DateTime)

In addition to the above, I would like to assign the days a class will happen:

• Name (Math 1)
• Code (MatA)
• Subject (Mathmatics)
• Description (Math is fun)
• BeginTime (DateTime)
• EndTime (DateTime)
• BeginDate (DateTime)
• EndDate (DateTime)
• Monday (bool)
• Tuesday (bool)
• etc.

I do not want to do the above, it just seems inefficient, especially when I need to call a class depending on the current date (ie. Get all classes that appear on Monday).

So, what kind of table structure should I have?

Thanks

Answer 1

You should create 2 tables, 1 for Classes and 1 for ClassSchedules. Join your tables with a ClassId column.

BTW, you shouldn’t need 2 columns for BeginTime and BeginDate, those should be stored in the same column — same goes for EndTime and EndDate.
