    摘要: A method, apparatus and program product that determine a density of a key value referenced in a database query over at least one range of rows, and utilize the determined density to optimize the database query. By doing so, the density of various key values may be determined and compared, and a bit map may be generated over the range of rows of the key value that is denser, resulting in a reduction of resources to build and use the bit map. Moreover, from the bit map over the range of rows to be selected after using the determined density, dense regions may be identified that can be used to optimize block I/O's according to the number of rows to be selected based on the query.

    摘要: A secure messaging system and method. The method can include the steps of receiving an encrypted message, the message having been encrypted using a token of a corresponding pervasive device; wirelessly verifying the presence of the pervasive device; and, if the presence can be verified, decrypting the message using the token. The verification step can include the steps of establishing a wireless link with the pervasive device; and, querying the pervasive device over the wireless link. In particular, the establishing step can include the step of establishing a Bluetooth link with the pervasive device. Furthermore, the querying step can include the step of requesting geographic coordinates which locate the pervasive device.

    摘要: The preferred embodiment of the present invention provides a method and apparatus for copying images from a source document to a destination document in a computer user interface. The preferred embodiment provides a user interface that gives the user the option to cut or copy information from an image and extract the textual information from the copied image in one cut and paste. The extracted text can then be pasted into the destination document as text. Thus, textual information from an image can easily and automatically be copied into text portions of the destination document. Alternatively, the image with the text removed can be copied into the destination in one cut and paste operation.

    摘要: A computer system and method display internal and external hypertext link definitions in different representations to simplify a user's recognition of the external/internal status of each hypertext link definition in a document. Additional information, such as the direction from an internal hypertext link definition to the location in the document pointed to by that definition, and/or the absolute or relative position of the location pointed to by an internal hypertext link definition, may also be displayed. Moreover, a computer system and method may also display the position of the location pointed to by an internal hypertext link definition on a scroll bar such that location information about a particular document is centralized within a common user interface component.

    摘要: The disclosed data stream optimization process is containing two logical entities, the first being the pre-comparison optimizer component and the second being the comparison component. The pre-comparison optimizer component performs two discrete tasks. First, the input data stream is written into a next state buffer. Second, the elimination of redundancies involves detecting and removing redundant screen attributes, since the terminal's execution time for processing a screen attribute is more than that required for a data character. The comparison component contains three distinct sub-components. First, non-data constructs such as commands and orders are optimized and placed in the outgoing data stream. Second, the screen image that is represented by the data stream is compared to the existing screen image to further reduce the outgoing data stream. This reduced version is further reduced when repeated characters and fields are replaced with repeat orders which take up less space within the outgoing data stream. Lastly, the reduced outgoing data stream is operated on by a post-optimizer sub-component. The post-optimizer sub-component will first determine whether repeated characters existing at the end of the outgoing data stream can be replaced a single repeat order. Then, the sub-component proceeds to remove any unnecessary cursor control orders. Upon completion, the fully optimized data stream is routed to the terminal or conversion facility.

    摘要: In an embodiment, a FIRSTIO execution plan is selected that has a lowest estimated execution time for finding a number of records that satisfy the query and are simultaneously viewable. An ALLIO execution plan is selected that has a lowest estimated execution time for finding all records that satisfy the query. The FIRSTIO execution plan is executed for a first time period to create a FIRSTIO result set. The ALLIO execution plan is executed for a second time period to create an ALLIO result set. The FIRSTIO result set is displayed if the FIRSTIO result set comprises more records than the ALLIO result set. The ALLIO result set is displayed if the ALLIO result set comprises more records than the FIRSTIO result set. In an embodiment, the first and second time periods expire in response to the expiration of a maximum time specified by the query.
