A signature-based Grid index design for main-memory RFID database applications

A large-scale RFID application often requires a highly efficient database system in data processing. This research is motivated by the strong demand for an efficient index structure design for main-memory database systems of RFID applications. In this paper, a signature-based Grid index structure is proposed for efficient data queries and storage. An efficient methodology is proposed to locate duplicates and to execute batch deletions and range queries based on application domain knowhow. The capability of the design is implemented in an open source main-memory database system H2 and evaluated by realistic workloads of RFID applications.

► The nature of main-memory databases and index for RFID applications is proposed.
► Bursty insertions/deletions and frequent duplicate identification are considered.
► Efficient data queries and updates are archived for the Grid index structure.
► The design is implemented in an open source main-memory database system, H2.
► Java native implementation in the weak generational hypothesis is resolved.
