摘要:
Particular embodiments generally relate to displaying database time using a treemap. A set of database time values is determined for a set of dimensions. The database time values measure performance of one or more databases by the time the database takes to respond to a request. The set of database time values is correlated to a set of cells in the treemap. A size of the cell is determined based on the database time value associated with it. For example, the database time value is correlated to an area of the cell. A layout of the set of cells is determined and the treemap is displayed using the layout. For example, the largest values of database time may be shown with the largest sized cells. This makes it easier for an administrator to review and analyze the database performance across multiple dimensions and determine problem areas affecting the performance of the one or more databases.

A user interface uses histogram equalization to allow easier manipulation and visualization of a data set, especially data sets having values that are not distributed uniformly. The user interface can show values of a data set in different colors or shades of colors, or a combination of these, or in grayscale. Additionally, values can also be represented according to a size or area relative to other values. A user may change views of the data by adjusting controls of the interface including slider bars, dials, tool bars, button bars, and others, and combinations of these.

Embodiments of the invention provide systems and methods for retrieving sequential information from a dataset. More specifically, retrieving sequential information from a dataset including one or more existing sequences can comprise receiving a query sequence representing a sequence against which the one or more existing sequences in the dataset is compared. The query sequence can be added to the dataset and a dotplot of the sequences in the dataset including the query sequence can be created. A determination can be made as to whether any of the one or more existing sequences match the query sequence based on the dotplot. For example, determining whether any of the one or more existing sequences match the query sequence based on the dotplot can comprise performing a line fitting process such as a regression-based line fitting process.

Embodiments of the invention provide systems and methods for analyzing sequential data. Analyzing the sequential data can include grouping or clustering data that are similar in some way, e.g., similar ranges of quantities, similar categories, etc. More specifically, a method for hierarchical clustering of sequential data can comprise creating a dotplot of the sequential data. The dotplot can represent a plurality of sequences within the sequential data. A number of clusters represented by the plurality of sequences can be initialized, e.g., one cluster per sequence. A pair of sequences of the plurality of sequences having a longest sequential match can be identified, e.g., based on a line fitting technique, and merged into a single cluster. Identifying a pair of sequences of the plurality of sequences having a longest sequential match and merging the identified pair of sequences into a single cluster can be repeated until a single cluster remains.

A method for providing symbolic access to a plurality of objects stored in a data storage is provided. An associative array comprising a plurality of associative array keys and a plurality of associative array values may be generated. A data array comprising a plurality of data array elements may be generated, such that each object stores a sortable property value of the object and an original offset of the object. A mapping table to map original offsets to modified offsets is generated. The mapping table includes a plurality of mapping table elements, and each associative array value is used as an offset into the mapping table, and each mapping table element storing a modified offset, each modified offset is a numeric value used as an offset into the data array.

Embodiments of the present invention provide a decision framework for selecting graph types based on attributes such as task, end-user, data-bound, and representational attributes. According to one embodiment, a computer-implemented method for aiding a user in selecting a graph type for a graph comprises receiving a selection of a graph type subset from the user, the graph type subset selected from a plurality of graph type subsets, the selection responsive to at least one task attribute corresponding to an intended use for the graph. The method further comprises generating a user interface to be displayed to the user, the user interface including an indication of at least one graph type in the selected graph type subset, an indication of at least one attribute, and an indication of whether the at least one graph type is appropriate in view of the at least one attribute, thereby providing guidance to the user in selecting an appropriate graph type.

A system and method for repurposing and augmenting document content by clipping, annotating, and reassembling portions of documents, and which may be used in an online or collaborative environment. As used herein the term “repurposing” includes packaging the online information in a manner so that it can be re-used by subsequent users for subsequent applications. An input device or menu referred to herein as a “clipbar” may be provided within a software application or in a kiosk environment that allows users to clip and annotate portions of online or other documents, while retaining both the document fragment's rendered image and its underlying structure. The clips thus created may be stored as collections (together with their associated user-specified and system-specified meta-data) in a form compatible with the other input documents. The collections can be immediately made available to other users in a collaborative fashion, and re-clipped as desired.

Embodiments of the invention provide systems and methods for analyzing sequential data. The sequential data can comprise a sequence of data points arranged in a particular order and thus representing a sequence. A number of such sequences can be analyzed, for example, to identify patterns or commonalities within the sequences or portions of sequences represented by the data. According to one embodiment, a method of identifying patterns in sequences of data points can comprise reading a set of sequential data. The sequential data can comprises a plurality of sequences and each of the plurality of sequences can represent an ordered sequence of tokens. A dotplot representing matches between each sequence of the plurality sequences can be generated. One or more patterns within the sequential data can then be identified based on the dotplot.
