A method and system for generating and searching a full text index. The fill text index includes the use of word numbers and a minimum delta which minimizes the need to access document level information during the application of search operators. Word registers having coordinated document level and word level information, as well as relevance information are used in search operations. Word numbers are clustered together during sub-operations in preparation for the next operation in a search quer...

A system and method for maintaining non-VSAM data set control information when moving a non-VSAM data set from a source volume to a target volume, even if the data set is not read into a host. After data is moved from the source volume set to the target volume set, each target volume is analyzed to determine the last track and record used by the data set and this information is recorded the in each target volume virtual table of contents (VTOC). In one embodiment where the volume geometry is ide...

A method and apparatus for creating a schema definition from a language-specific metamodel of a data structure written in a legacy computer language involves walking through the nodes of the metamodel, and creating corresponding schema element objects in a schema tree that is serialized to create the schema definition. The creation of the schema element objects follows rules, and permits the definition of nested data structures having conjunctive-type and disjunctive-type membership.

An online search system generates an index of documents using index information received from a library. Some documents have restricted access; some documents may not be available online. The search system provides links to documents in the library as well as other sites based on a search, and may include link resolvers received from the library. The search system provides access links to the link resolvers if an identifier, such as a user identification or IP address, matches an affiliation lis...

Some embodiments provide a system including a database, two or more data access objects, and a proxy object. In some such embodiments, each data access object has exclusive access privileges to a subset of data within the database. Further each object includes one or more of a read method that provides access to data and a write method that causes data to be stored. In such embodiments, the proxy object accesses data via data access object methods and includes a valuate method, the execution of ...

A data processing apparatus is disclosed which includes a reproducing element for reproducing each of a plurality of content data items a reproduction status detecting element for detecting status of each content data item being reproduced by the reproducing element a selecting element for selecting the content data item being reproduced by the reproducing element depending on the reproduction status of the content data item detected by the reproduction status detecting element a content identif...

A system and method for storing computer files in a destination file is described, which may be an incremental backup system. File headers related to the files may be stored in a file index separate from a data file, or subsequent versions may be stored in the same data file while maintaining earlier versions. File headers may include locations of files, checksums, metadata about individual blocks corresponding to the data files. A system may include a client application program stored on a clie...

A method for testing an intent log for a file system that includes creating a first file system, issuing a command to freeze the first file system, performing a plurality of commands on the first file system to obtain a plurality of deltas, wherein each of the plurality of deltas is stored in the intent log and is not committed to the first file system, copying the first file system to obtain a second file system, committing each of the plurality of deltas in the intent log to the second file sy...

A file system for displaying items of different types and from different physical locations. In accordance with one aspect of the invention, a wide scope of items may be available. In other words, the system is able to represent items from multiple physical locations (e.g., different hard drives, different computers, different network locations, etc.) so that to a user all the items appear to be from one location. The file system utilizes virtual folders. The virtual folders expose regular files...

A directory shell references one or more directories. Each directory comprises a plurality of directory objects each having object attributes and attribute data. One or more categories in the directory shell are associated with one or more directory objects and at least a portion of the associated object attribute. A user interface is operable for a user to query the categories in the directory shell. A directory interface is operable to send a search request to the directories in accordance wit...
