International Classification:

G06F007/00

US Classification:

707/003000

Abstract:

A method, apparatus and article of manufacture is provided for loading data from a remote data source record by record, in a computer system network connecting a source site and a target site via a database connection communication line. The source site has at least one data source and a Distributed Relational Database Architecture (DRDA) software server having multi-database access to DBMSs. The target site requests data loading from the source site DRDA via a block of Structured Query Language (SQL) statements. Data are transported record by record via the database connection communication line according to the DRDA communication protocol, wherein the target site loads records concurrently with the unloading of records in the source site. The data loading may also be performed in a pipeline manner, loading data records in multiple partitions with a plurality of parallel streams, pointed to by a plurality of data source partition cursors.

International Classification:

G06F 17/00

US Classification:

707102000

Abstract:

A method for indexing a plurality of documents, that includes a plurality of duplicate documents, first identifies one or more duplicate groups of documents from among the plurality of documents. Then, one index of content for the duplicate group is created instead of indexing the content from every document within the duplicate group. However, in contrast to the content index, an index of metadata for each of the documents in the duplicate group is created. Thus the content of each duplicate group is indexed only once, while a search engine using such indexing techniques retains the capability to answer queries as if the duplicated content was indexed for each document of the group.

International Classification:

G06F 17/30

US Classification:

707009000

Abstract:

Techniques are provided for processing a search request. One or more indexed levels of access control list information are stored in a search index for each document identified in the search index. An interim result set is generated by matching the one or more indexed levels of access control list information associated with each said document to one or more security groups associated with the search request. A final result set is generated from the interim result set by performing impersonation.

US Classification:

707005000

Abstract:

Disclosed is a technique for building an index. A new indexis built and an anchor text tableand a duplicates tabletare output using a stores, a delta store, and previously generated global analysis computations, wherein the previously generated global analysis computationsinclude an anchor text table, a rank table, and a duplicates table. New global analysis computationsare generated using the anchor text table, the duplicates table, and the previously generated global analysis computations.

International Classification:

G06F 7/06

US Classification:

707 3, 707E17014

Abstract:

A method for querying multifaceted information. An inverted index is constructed to include unique indexed tokens associated with posting lists of one or more documents. An indexed token is either a facet token included in a document as an annotation or a path prefix of the facet token. The annotation indicates a path within a tree structure representing a facet that includes the document. The tree structure includes nodes representing categories of documents. Constructing the inverted index includes generating a full path token and an associated full path token posting list. A query is received that includes constraints on documents. The constraints are associated with indexed tokens and corresponding posting lists. An execution of the query includes identifying the corresponding posting lists by utilizing the constraints and the inverted index and intersecting the posting lists to obtain a query result.

Abstract:

A method of repairing bone defects by use of suspensions containing purified atelopeptide, reconstituted, fibrillar skin collagen or bone collagen powder or mixtures thereof is disclosed. The suspensions provide matrices for conductive growth of bone into the defect. The skin collagen may also be lyophilized and used in the form of mats.
