Abstract: Preliminarily or according to amendment to a basic table, an intermediate link table indicating a link condition for directly or indirectly linking two optional basic tables is automatically generated by obtaining an indirect link condition for linking basic tables which cannot be directly linked based on a link condition of basic tables which can be directly linked. By only inputting minimal information, a structured query language (SQL) statement is automatically generated according to the input information using the intermediate link table. Thus a relational database can be searched for desired data even when a user does not fully understand the structure of a table or field information in the relational database.

Abstract: Method and apparatus for backing up and restoring data in a computer system is disclosed. A segment of data, such as a virtual disk partition, may be backed up at a physical level from a primary storage device to a backup storage device. A logical element within the segment of data, such as a data file, may be restored from the backup storage device to the primary storage device. In one embodiment, this is achieved by restoring the segment to a scratch memory area and using a client computer to logically restore the logical element.

Abstract: A computer system in accordance with the invention includes a primary desktop computer and an auxiliary portable computer. The two computers are configured to work together--documents such as word processing documents are at times downloaded from the desktop computer for viewing and editing on the portable computer. However, the desktop computer uses TrueType outline fonts, while the portable computer uses raster fonts. The desktop computer includes a conversion program that is automatically invoked when the user copies an outline font file to the portable computer. The conversion program makes calls to the graphics device interface of the desktop computer to render outline character glyphs to a bitmap. The resulting bitmap is used as the basis of a rasterized character glyph. A set of glyphs is converted in this manner and compiled into a raster font file.

Abstract: A method and system for manipulating the display of multiple software applications within a data processing system which are displayed within multiple windows which at least partially overlap in a selected order from a bottom position to a top position. A depth control window is displayed within the data processing system in response to a user input. The depth control window includes multiple graphic elements arranged in the selected order wherein each graphic element corresponds to a software application window within the data processing system. The display of software application windows within the data processing system is then altered, in response to a user selection of a particular graphic element, to display a particular application window which corresponds to the selected graphic element and each window which is overlapped by the window displaying the particular application.

Abstract: Replacing a human operator, an automated message processing system communicates with a data storage subsystem. The automated message processing system receives messages from the data storage subsystem signalling the insertion of an item of removable data storage media, such as a tape cartridge, into a tape library of the data storage subsystem. Such messages are selectively routed to one of many specialized expert local facilities, or ELFs. In response to input from the data storage subsystem, the ELFs generate appropriate output messages, ultimately transmitted to the data storage subsystem to direct cataloguing, categorization, and even labeling of inserted media.

Abstract: The present invention is a method for integrating a file system with a RAID array that exports precise information about the arrangement of data blocks in the RAID subsystem. The file system examines this information and uses it to optimize the location of blocks as they are written to the RAID system. Thus, the system uses explicit knowledge of the underlying RAID disk layout to schedule disk allocation. The present invention uses separate current-write location (CWL) pointers for each disk in the disk array where the pointers simply advance through the disks as writes occur. The algorithm used has two primary goals. The first goal is to keep the CWL pointers as close together as possible, thereby improving RAID efficiency by writing to multiple blocks in the stripe simultaneously. The second goal is to allocate adjacent blocks in a file on the same disk, thereby improving read back performance. The present invention satisfies the first goal by always writing on the disk with the lowest CWL pointer.

Abstract: Distributed information integrating method and apparatus for collecting data requested by a program at a data request side, integrating the collected data and supplying the integrated data to the request-side program irrespective of the existence of a processing device storing the data and a transmission medium. An event linking data table 232 stores the name of data to be collected in response to an occurring event and a transmission destination of the collected data. Filtering processing 222 refers to the event linking data table 232 in response to an event occurring on a self processing device and a message event received through a transmission medium to collect the data stored in the self processing device, and transmits the collected data to a transmission destination. A data integration management table 233 sets the items of data to be integrated while dividing the items for every data name of the collection data.

Abstract: An object management system for storing persistent object oriented objects, includes an object vault, a structural type manager and a digital library. The object vault is connected to the structural type manager and the digital library is connected to the structural type manager. An application program is connected to the object vault. Objects to be stored are represented as a Key Value Dictionary (KVD) in which attributes, or metadata, relating to the objects are stored as key-value pairs. Objects are categorized as having different structural types in which certain attributes for objects having the same structural type are cataloged to facilitate indexing and searching for the objects. The structural type manager maintains a mapping between structural types and a subset of keys for the structural types as well as corresponding database references for cataloging the object attributes.

Abstract: In a computer system, a data structure is provided in memory for storing one or more data files from an external device. The data files stored in the data structure are accessible by a number of processes executing in the computer system. The computer system includes a storage device such as a cache for storing data from a subset of pages of the memory. Each of the pages of the cache is referred to as a cache page, having an associated cache page address. A physical address is allocated for storing each page of a retrieved data file stored in the data structure such that a cache page address portion of the physical address is selected from the available cache page addresses. The physical address is further selected such that the cache page addresses are substantially evenly distributed amongst the pages of the retrieved data file and the data structure in order to minimize thrashing in the cache and enhance performance.
