To convert to first normal form (1NF) either remove the repeating group to a new relation along with a copy of the original key attribute(s), or remove the repeating group by entering appropriate data in the empty columns of rows containing the repeating data. You can organize data into tables, rows, columns, and index it to make it easier to find relevant information. It’s a process that helps organize and structure data efficiently while minimizing redundancy and ensuring data integrity. Thomas G. The levels of normalization are listed below, in order of strength (with UNF being the weakest): UNF (Unnormalized Form) A database is in A database is in 5NF when there is no join dependency present in the table / database.
