“…In [39], Wu et al proposed a fast recovery scheme for flash-based file systems, which commits log records into a special check region in order to avoid scanning the entire flash storage during recovery. Byun [14] proposed a new locking scheme called flash-two-phaselocking (F2PL) for concurrency control in a flash-based DBMS. F2PL achieves a high transaction performance by efficiently handling slow write/erasure operations in lock management processes.…”

Owing to recent advances in semiconductor technologies, flash disks have been a competitive alternative to traditional magnetic disks as external storage media. In this paper, we study how transaction recovery can be efficiently supported in database management systems (DBMSs) running on SLC flash disks. Inspired by the classical shadow-paging approach, we propose a new commit scheme, called flagcommit, to exploit the unique characteristics of flash disks such as fast random read access, out-place updating, and partial page programming. To minimize the need of writing log records, we embed the transaction status into flash pages through a chain of commit flags. Based on flagcommit, we develop two recovery protocols, namely commit-based flag commit (CFC) and abort-based flag commit (AFC), to meet different performance needs. They are flexible to support no-force buffer management and fine-grained concurrency control. Our performance evaluation based on the TPC-C benchmark shows that both CFC and AFC outperform the state-of-the-art recovery protocols.

“…These researchers attempted to integrate some social network applications that include MySpace, Facebook, and Wikipedia, as well as blogs with online teaching lessons in order to meet the needs of the students of 21st century [4]. In local efforts, the basic structure of a considerable part of the education and training institutions' courseware production systems was consistent with almost all of the major software vendors, such as PowerPoint (PPT) [5] and Flash [6]. This type of software uses the page editing mode during the production of online courseware, which allows its own independence.…”

Abstract-Since the second decade of the 21st century, the rapid development of computer information technology promoted the internet use throughout society. We are now in an era in which life and learning are closely intertwined with the internet. In Western Europe, the United States, and other developed countries, teaching activities by online multimedia and offline technology have been long implemented. However, local online automatic generation software is inflicted with many issues, particularly, with the inability to meet the most student needs. Hence, we developed a new online courseware generation system to address this problem. After testing, the system functioned effectively, and the educational effect enhanced significantly.

PCMLogging: Optimizing Transaction Logging and Recovery Performance with PCM

Phase-change memory (PCM), as one of the most promising next-generation memory technologies, offers various attractive properties such as non-volatility, byte addressability, bit alterability, and low idle energy consumption. Recently, PCM has drawn much attention from the database community for optimizing query and transaction performance. As a complement to existing work, we present PCMLogging, a novel logging scheme that exploits PCM for both data caching and transaction logging to minimize I/O accesses in disk-based databases. Specifically, PCMLogging caches dirty pages/records in PCM and further maintains an implicit log in the cached updates to support database recovery. By integrating log and cached updates, PCMLogging enables simplified recovery and prolongs PCM lifetime. Furthermore, using PCMLogging, we develop a wear-leveling algorithm, that evenly distributes the write traffic across the PCM storage space, and a cost-based destaging algorithm that adaptively migrates cached data from PCM to external storage. Compared to classical write-ahead logging (WAL), our trace-driven simulation results reveal up to 1∼20X improvement in system throughput.
