RFID Data Management

Radio Frequency IDentification (RFID) is emerging as an all pervasive ubiquitous technology which holds the promise of revolutionizing supply chain management applications. The volume of information generated by such system is enormous. Managing such high volume of data poses the challenges to applications as well as back-end databases. This data is redundant, needs to be consolidated and reduced/transformed so that it occupy less space in the database. In doing so, care must be taken that no useful information is lost. Researchers in database community have presented techniques and models for warehousing as well as cleaning/filtering RFID data. In this report we discuss the RFID technology, characteristics of RFID data, various challenges in handling RFID data and present literature survey of various data warehousing techniques. However this auto-ID technology brings new kinds of risks and security issues which we are not touching as far as this report is concerned.
