Configuration files are often stored in XML (Extended Markup Language), which is a flat file database with some quite specific delimiters, such as "greater than" and "less than" (<>) symbols. So a flat file database is disadvantageous to a network user, who is accessing a multi-access, multi-tasking relational online database which can be viewed from many different aspects.

This is known as ‘data redundancy’ and is a waste of (hard disk) space. Backup: It is possible to take faster and automatic back-up of database stored in files of computer-based systems. Many software applications are created with flat file databases. Each record within the table contains the same fields with the same type of information in each field, although of course the specific information you enter into each separate field is different. Disadvantage is that it is inflexible and usually requires multiple entry of the same data. It is poor database in terms of complex queries. These relate to the repetition of data stored in the database (known as ‘data redundancy’) as well as problems to do with adding and removing records or changing the data in records.
