Let say I have these fields: website, email, phone, fax, street_address, city, country, logo, slogan...
As I know I have 2 ways to save data into a custom table:
1. Create columns in the table for each field.
2. Create a group field and put these fields into that group, and then create 1 column for that group field (I'll create more groups/columns, also nested groups for other data).
From the viewpoint of speed, which way is faster if I want to show the data fields to the front end?
