Solution

The importance of every column in a table having a unique name in 1NF (First Normal Form) is as follows:

  1. To prevent data inconsistency: Unique column names help in maintaining the consistency of data. If two columns have the same name, it may lead to confusion and errors, resulting in inconsistent data.

  2. To ensure data redundancy: Unique column names help in avoiding unnecessary duplication of data. If columns have unique names, it is easier to identify and eliminate redundant data.

  3. To avoid confusion during data retrieval and manipulation: Unique column names make it easier to retrieve and manipulate data. If columns have the same name, it may lead to confusion and errors during data retrieval and manipulation.

  4. To facilitate data compression: Unique column names can also help in data compression. If columns have unique names, it is easier to compress the data as there is less redundancy.
