Patent number: 8965857Abstract: Methods, systems, and computer program products are provided to manage a database system. The method includes locking during a database system idle time access by the database system to a data page of a data allocation unit, compressing during the database system idle time a data stored in the locked data page, and recording during the database system idle time an indication that the compressed and locked data page includes free storage space, wherein unlocked data pages of the data allocation unit are accessible by the database system during the compressing of the data stored in the locked data page. Thus, the data page may be compressed during idle time and the space freed therein may be used during a subsequent run time without the need for a reorganization of the data pages within the corresponding table (as in, for example, operation of a reorg+rebuild SQL command combination).Type: GrantFiled: December 28, 2012Date of Patent: February 24, 2015Assignee: Sybase, Inc.Inventors: Panfeng Zhou, Katsunori Terada, Yanhong Wang

Publication number: 20100257181Abstract: Aspects for achieving efficient data access to data elements in a relational database management system are provided. In a computer-implemented method aspect, the efficient data access occurs by establishing a hash table for data elements of a database in a predetermined continuous space of allocated storage, and optimizing utilization of the hash table during database query operations through linear hashing, wherein extension of the hash table occurs automatically to increase a number of pages in the hash table without discernible interruptions of data access to the data elements.Type: ApplicationFiled: April 1, 2009Publication date: October 7, 2010Applicant: Sybase, Inc.Inventors: Panfeng ZHOU, Katsunori TERADA, Yanhong WANG

Patent number: 7293040Abstract: A system and methodology for database migration between platforms is described. In one embodiment, for example, a method is described for migrating a database across platforms having different byte order formats (e.g., big-endian and little-endian), the method comprises steps of: when the database is loaded on a given platform, determining whether the database requires conversion to match the byte order format of the given platform; identifying particular portions of the database to be converted if the database is determined to require conversion; and converting the particular portions of the database to the byte order format of the given platform.Type: GrantFiled: February 28, 2005Date of Patent: November 6, 2007Assignee: Sybase, Inc.Inventor: Katsunori Terada

Patent number: 5198685Abstract: A photoelectric conversion apparatus having a thin plate glass wear-resisting layer is formed on photoelectric conversion devices, drive circuit and signal lines. An original document is disposed on the wear-resisting layer to confront the photoelectric conversion devices. Light is emitted from a light source disposed to confront the light transmissive substrate on the side opposing the original document, transmitted through a light transmissive substrate and applied to the original document. Reflected light from the original document is received by the photoelectric conversion devices so that electric signals transmitted from the photoelectric conversion devices can be read out through the signal lines.Type: GrantFiled: July 29, 1991Date of Patent: March 30, 1993Assignee: Canon Kabushiki KaishaInventors: Masashi Kitani, Hisanori Tsuda, Katsunori Terada, Satoshi Itabashi, Tetsuya Shimada
