5890148 System and method for generating uniqueness information for optimizing an SQL query March 30, 1999
A system and method of determining uniqueness properties of an expression. A root of the expression is first determined, where the root is one of a base relation, a unary operation or a binary operation. Once the root is determined, a first procedure of an augmented unique process is cal
5696960 Computer program product for enabling a computer to generate uniqueness information for optimizi December 9, 1997
A system and method of determining uniqueness properties of an expression. A root of the expression is first determined, where the root is one of a base relation, a unary operation or a binary operation. Once the root is determined, a first procedure of an augmented unique process is cal
5659728 System and method for generating uniqueness information for optimizing an SQL query August 19, 1997
A system and method of determining uniqueness properties of an expression. A root of the expression is first determined, where the root is one of a base relation, a unary operation or a binary operation. Once the root is determined, a first procedure of an augmented unique process is cal
5629695 Order preserving run length encoding with compression codeword extraction for comparisons May 13, 1997
The present invention provides a system and method for the dictionary ordering of keys after expansion, compression and concatenation of their key parts. After each key part has been expanded through padding, each substring of identical characters of length greater than or equal to three
5619199 Order preserving run length encoding with compression codeword extraction for comparisons April 8, 1997
The present invention provides a system and method for the dictionary ordering of keys after expansion, compression and concatenation of their key parts. After each key part has been expanded through padding, each substring of identical characters of length greater than or equal to three
5586315 Computer program product for off-loading host-based DBMS predicate evaluation to a disk controll December 17, 1996
A computer program product, such as a pre-recorded software program on a floppy disk, is disclosed, for use with a processing and database system for off-loading, to disk controller, the extraction of committed data. Responsive to the pre-recorded program instructions, the system first
5534861 Method and system for adaptively building a static Ziv-Lempel dictionary for database compressio July 9, 1996
A system for creating a static data compression dictionary adapted to a hardware-based data compression architecture. A static Ziv-Lempel dictionary is created and stored in memory for use in compressing database records. No data compression occurs during dictionary construction. A f
5495601 Method to off-load host-based DBMS predicate evaluation to a disk controller February 27, 1996
A method is disclosed for a database system for [off-loading] off-loading, to disk [controller] controller, the extraction of committed [data involving the] data. The system first [picking] picks a Commit.sub.-- LSN value and [insuring] insures all the data modified prior to the Comm
5442350 Method and means providing static dictionary structures for compressing character data and expan August 15, 1995
Ziv-Lempel-type compression and expansion using separate static compression and expansion dictionaries as opposed to a single adaptive dictionary. The static dictionaries make random access processes usable for short data records instead of only long sequential data streams. Degree of
5424732 Transmission compatibility using custom compression method and hardware June 13, 1995
Describes novel methods for compressing data character strings into "storage optimized indices" (SOIs) and stores their adaptive Ziv Lempel (AZL) indices, called "evolution based indices" (EBIs), in fields in corresponding entries in a SOI dictionary. The method also compresses data
5412384 Method and system for adaptively building a static Ziv-Lempel dictionary for database compressio May 2, 1995
A system for creating a static data compression dictionary adapted to a hardware-based data compression architecture. A static Ziv-Lempel dictionary is created and stored in memory for use in compressing database records. No data compression occurs during dictionary construction. A f
5323155 Semi-static data compression/expansion method June 21, 1994
A method of transmitting compressed data using a Ziv-Lempel compression/expansion algorithm, using an adaptive Ziv-Lempel (AZL) dictionary modified to a mature state. The mature state is signaled by a time to freeze signal sent as a switch-over signal from a transmitting location to
