Disclosed are a method, information processing system, and computer readable medium for managing table scan processes. The method includes monitoring a plurality of storage medium table scan processes. Each storage medium table scan process in the plurality of storage medium table sc
8005872 Method for fast deletion of physically clustered data August 23, 2011
A computer implemented method, apparatus, and computer usable program code for deleting rows in a multidimensionally clustering database. A multidimensional clustering processor receives a request to delete a set of multidimensionally clustering data. The multidimensional clustering
7937541 Speed selective table scan operation May 3, 2011
Disclosed are a method, information processing system, and computer readable medium for scanning a storage medium table. The method includes retrieving location information associated with at least one other storage medium table scan. A storage medium table scan is started at a locat
7895171 Compressibility estimation of non-unique indexes in a database management system February 22, 2011
A method, information processing system, and computer readable storage product estimate a compression factor. A set of key values within an index are analyzed. Each key value is associated with a record identifier ("RID") list comprising a set of RIDs. The index is in an uncompressed
7885976 Identification, notification, and control of data access quantity and patterns February 8, 2011
A device for limiting access to data in a database includes an input for receiving a request to access data in a database and a processor that is communicatively coupled to the input and allows access to the data in the database. A data counter for counting an instantaneous rate of data
7836036 System and method for estimating distances between multiple index-driven scan operations November 16, 2010
A method and processor to determine distances between multiple index driven scan operations. A first anchor index entry is identified during a first index scan and stored. A first number of index entries between the first anchor index entry and a first index scan location being processed
7765211 System and method for space management of multidimensionally clustered tables July 27, 2010
An information retrieval system and method are provided for minimizing the number of blocks searched in a cell before recording a new record in the table and determining which block can be assigned if a table has space available to store a new record in the case an additional block shoul
7685181 Method and system for utilizing a hierarchical bitmap structure to provide a fast and reliable m March 23, 2010
A method and system utilizes a hierarchical bitmap structure to represent deleted data sets. Each level in the hierarchical bitmap structure may have progressively larger size and represent finer granularity of number of data blocks than its parent level. A method in one aspect may compr
7631014 Method and apparatus for fast deletion of physically clustered data December 8, 2009
A computer implemented method, apparatus, and computer usable program code for deleting rows in a multidimensional clustering database. A multidimensional clustering processor receives a request to delete a set of multidimensionally clustered data. The multidimensional clustering pro
7519583 Detecting and tracking monotonicity for accelerating range and inequality queries April 14, 2009
A computer implemented method, apparatus, and computer usable program code for detecting monotonicity. A determination is made as to whether a function that is assumed to be monotonic will remain monotonic after performing an operation in response to receiving the operation. The oper
7516117 Method for accelerating range queries using periodic monotonic properties of non-monotonic funct April 7, 2009
A method for accelerating range queries using periodic monotonic properties of non-monotonic functions including mapping a base column x to an existing index on a column y that is correlated with column x through a periodic piecewise monotonic function F(x), rewriting an index constr
