Since then, Pramod has applied the practices and processes to many projects. Pramod writes and speaks about database administration on evolutionary projects, the adoption of evolutionary processes with regard to databases, and evolutionary practices' impact upon database administration, in order to make it easy for everyone to use evolutionary design in regards to databases.
