Data classification: database administrators can easily categorize and store data in the relational database which can then be interviewed and filtered to extract information for reports.
Updates run quickly because no data is duplicated in multiple places.
Insertion is fast because there is only one insertion point for one data and no copying is required.
Tables are typically smaller than those found in non-standard databases. This generally allows the tables to fit in the cache, thus providing faster performance.
Data integrity and consistency is an absolute must if the database is ACID compliant. A standardized database is of great help in such an endeavor.
