The Transformation of Relational Database to Wide Column Store Database

Due to the popularity of big data applications, such as social networking, e-commerce, etc., companies need to quickly access huge amounts of data. Under such conditions, a relational database (RDB) cannot meet the demand, and more and more companies decide to switch to NoSQL database to maintain competitiveness. It's necessary to convert data from an RDB to a NoSQL database for the companies that have a lot of operation data in an RDB. Therefore, this paper proposes an algorithm to explore how to convert the schema of RDB into the ones of Wide Column Store DB (WCSDB), and how to import actual data from an RDB into a WCSDB.
