摘要： A method for displaying portfolio risk is described. The method includes receiving a time series corresponding to a weight and a desirability of each of an asset in a portfolio. The method further includes maintaining the time series corresponding to the weight and the desirability of each of the assets in the portfolio. The method also includes maintaining a standard time series for comparison with the time series corresponding to the weight and the desirability of each of the assets in the portfolio. The method further includes displaying, for each asset in the portfolio, a quantity based on desirability versus a quantity based on the correlation between desirability and the standard time series over two specified windows of time. The method also includes displaying trend information based on moving two specified windows of time from the past to the point where at least one window is the most current window.

摘要： The system and method of the present invention provide for automatic on-demand replication in a replication cluster of content management servers. A replication manager of a content management server receives newly created, modified, and deleted application item types along with their associated physical tables and automatically forwards the received application item types on-demand to the replication managers of other content management servers of the replication cluster.

摘要： A distributed collection of web-crawlers to gather information over a large portion of the cyberspace. These crawlers share the overall crawling through a cyberspace partition scheme. They also collaborate with each other through load balancing to maximally utilize the computing resources of each of the crawlers. The invention takes advantage of the hierarchical nature of the cyberspace namespace and uses the syntactic components of the URL structure as the main vehicle for dividing and assigning crawling workload to individual crawler. The partition scheme is completely distributed in which each crawler makes the partitioning decision based on its own crawling status and a globally replicated partition tree data structure.

摘要： A relational data base management system that stores and retrieves large data objects (LOBs) from data base storage includes a data manager that maintains LOB data space allocation according to the buddy system with two types of allocation pages, called regular buddy space (RBS) pages and super buddy space (SBS) pages. The RBS pages control buddy spaces comprising equal-size areas of the LOB data space in which LOB buddy segments are stored. The SBS pages control the RBS pages. The RBS pages include a pointer array that contains the forward-most location of where searching for a free storage space should begin and a counter array that indicates the number of free buddy segments in a buddy space for a particular buddy segment size. The SBS pages include analogous pointer and counter arrays that refer to the RBS pages and indicate the location and extent of free storage space, and also include a divided-space array and an SBS page directory.
