Traditional RDBMS (relational database management system) have been the conventional standard for database management throughout the age of the internet. This is also known as Traditional row-column databases used for both transactional systems, reporting, and archiving. The architecture behind RDBMS is such that data is organized in a highly-structured manner, following the relational model. RDBMS is now considered as a declining database technology. While the organization of the data keeps the warehouse very "neat", the need for the data to be well-structured actually becomes a substantial burden at extremely large volumes which results in performance declines as size gets bigger. Thus RDBMS is generally not considered as a solution to meet the needs of big data.
