What are advantages of using a relational database instead of a flat file? Check all that apply.

A relational database links related tables, so you can select specific fields to generate reports and more easily sort, filter, summarize, and compare information. Its structure can also reduce duplicate data by storing a piece of information once and connecting it to related records. A flat file can also store data in rows and columns, so tabular format alone is not an advantage of relational databases; relational databases are not generally easier to set up, either.
