A data processing system includes a query progress analyzer. The database processing system comprises a receiver that receives database queries including a target query directed to a database and a query analyzer. The query analyzer is coupled to the receiver and analyzes progress status of the target query based on comparison of measured target query resource usage to resource usage predicted from a query plan of the target query and measured system resource usage.

There is provided a system and method for creating a value-based stacked bar chart. More specifically, in one embodiment, there is provided a computer readable medium comprising code adapted to sort a plurality of data entries by transaction value, wherein the plurality of data entries correspond to a stack type; code adapted to assign each of the plurality of data entries to one or more cells associated with the stack type, code adapted to assign a color to the one or more cells, and code adapted to shade the color of a subset of the one or more cells based on the transaction value of the data entries assigned to the cells in the subset.

Provided are, among other things, systems, methods and techniques for displaying data by accessing a set of data records that have associated indexes and generating pixels to represent the data records, the colors of the pixels being based on attribute values of the data records. The pixels are arranged into lines based on the associated indexes, with each line corresponding to a segment of indexes and adjacent lines corresponding to adjacent segments, and the arranged pixels are displayed.

A method for generating a pixel-oriented graph provides visual boundaries for representing aggregate information. The present method for generating a pixel-oriented graph includes determining a visual boundary for representing an aggregate of a set of information depicted in the pixel-oriented graph and constructing a set of pixel blocks that represent the information such that the pixel blocks are visually distinguished by the visual boundary. A method according to the present techniques employs a visual weight to classify labels and high weight information is shown and other information is made invisible and hidden in the property of a graph.

In a method for estimating a loaded execution runtime of database query, a database query for a database is received for a loaded database. Load information for the database is received. A prediction of query runtime tree is accessed. The prediction of query runtime tree is built from historical query information regarding historical database queries previously executed on the database. The prediction of query runtime tree includes a classifier function adjusted for an historical impact of loading of the database. The database query is processed through the prediction of query runtime tree, such that a loaded execution runtime of the database query is estimated based upon information pertaining to historical database queries similar to the database query.

In a method of preserving characteristics of desensitized database information for use in database management system benchmarking, at least one column of sensitive data from a database is accessed. The at least one column of sensitive data is sorted into a sorted data representation. Desensitized data is generated by sequentially mapping ascending different values of the sorted data representation to ascending desensitized values generated according to a strictly monotone increasing randomly generated function. The mapping results in a plurality of mapped desensitized values which are associated with the sorted data representation. The mapped desensitized values are unsorted into a desensitized database according to sorting information related to the sorted data representation. As a result of the unsorting, cardinalities of the at least one column of sensitive data are maintained within the desensitized database.

The disclosed embodiments relate to a system and method for providing a graphical representation of data. Embodiments of the present invention comprise: abstracting a plurality of parameters from the parameter set, dividing the plurality of parameters into data groups, defining a plurality of partitions for a graphical representation, mapping the data groups to corresponding nodes on the plurality of partitions, and connecting the nodes graphically with indicia that indicates an association between data groups.
摘要:
Document clustering method and system utilizing both the log-based clustering method and the content-based clustering method are disclosed. The method includes the steps of generating log-based document clusters and combining vectors from the log-based document clusters with individual document clusters for content-based clustering analysis. The log-based document clusters are generated by accessing the retrieval session log, clustering the retrieval sessions, and combining the documents opened during each of the sessions of session clusters.
摘要:
A web transaction visualization system may include at least one web transaction visualization (WTV) processor adapted to automatically extract massive amounts of web transaction data from at least one data source for visual classification based on at least one aggregate transaction metric and to display the classified web transaction data interactively in three dimensions without overlapping.
摘要:
A method and system are disclosed for monitoring the performance of web-based services. The method comprises receiving a transaction from a client and routing the transaction to an appropriate web service for execution of the transaction. During execution of the transaction, performance data relating to the execution of the transaction is monitored and logged. The collected performance data is then queried based on pre-defined performance metrics and web service performance reports are generated. A system for the foregoing method is also disclosed.
