The method updates a raw database using an input data stream based on an input temporal value associated with the input data stream and a raw temporal value associated with the raw database. The method includes updating a derived database associated with the data storage system using the updated raw database based on the input temporal value, a derived temporal value and a user-defined relationship, the derived temporal value being associated with the derived database. The invention also relates to a computer-readable medium. The computer readable medium including instructions, wherein execution of the instructions by at least one computing device updates a data storage system. The invention further relates to a data storage system. The system includes a raw database, a derived database and a computing device operatively coupled to the raw database and the derived database.
