Detailed explanation-2: -A table has records (rows) and fields (columns). Fields have different types of data, such as text, numbers, dates, and hyperlinks. A record: Contains specific data, like information about a particular employee or a product.

Detailed explanation-3: -MySQL has hard limit of 4096 columns per table, but the effective maximum may be less for a given table. The exact column limit depends on several factors: The maximum row size for a table constrains the number (and possibly size) of columns because the total length of all columns cannot exceed this size.

Detailed explanation-4: -In Access, you can define up to 255 fields in a table. If you create 255 fields and then delete 10, Access does not release the fields from the internal column count. Also, for every field whose properties you modify, Access creates a new field and does not release the original field from the internal column count.
