Regular Path Query Evaluation Sharing a Reduced Transitive Closure Based on Graph Reduction
Inju Na, Ilyeop Yi, Kyu-Young Whang +2
Regular path queries (RPQs) find pairs of vertices of paths satisfying given regular expressions on an edge-labeled, directed multigraph. When evaluating an RPQ, the evaluation of…
Odysseus/DFS: Integration of DBMS and Distributed File System for Transaction Processing of Big Data
Jun-Sung Kim, Kyu-Young Whang, Hyuk-Yoon Kwon +1
The relational DBMS (RDBMS) has been widely used since it supports various high-level functionalities such as SQL, schemas, indexes, and transactions that do not exist in the O/S f…
ODYS: A Massively-Parallel Search Engine Using a DB-IR Tightly-Integrated Parallel DBMS
Kyu-Young Whang, Tae-Seob Yun, Yeon-Mi Yeo +3
Recently, parallel search engines have been implemented based on scalable distributed file systems such as Google File System. However, we claim that building a massively-parallel…
Page-Differential Logging: An Efficient and DBMS-independent Approach for Storing Data into Flash Memory
Yi-Reun Kim, Kyu-Young Whang, Il-Yeol Song
Flash memory is widely used as the secondary storage in lightweight computing devices due to its outstanding advantages over magnetic disks. Flash memory has many access characteri…
Structural Consistency: Enabling XML Keyword Search to Eliminate Spurious Results Consistently
Ki-Hoon Lee, Kyu-Young Whang, Wook-Shin Han +1
XML keyword search is a user-friendly way to query XML data using only keywords. In XML keyword search, to achieve high precision without sacrificing recall, it is important to rem…
Progressive Processing of Continuous Range Queries in Hierarchical Wireless Sensor Networks
Jeong-Hoon Lee, Kyu-Young Whang, Hyo-Sang Lim +2
In this paper, we study the problem of processing continuous range queries in a hierarchical wireless sensor network. Contrasted with the traditional approach of building networks…
A Logical Model and Data Placement Strategies for MEMS Storage Devices
Yi-Reun Kim, Kyu-Young Whang, Min-Soo Kim +1
MEMS storage devices are new non-volatile secondary storages that have outstanding advantages over magnetic disks. MEMS storage devices, however, are much different from magnetic d…
