Method And Apparatus For Virtual Memory Mapping And Transaction Management In An Object-Oriented Database System

View page
US Patent:
6795898, Sep 21, 2004
Filed:
Mar 6, 2001
Appl. No.:
09/800257
Inventors:
Daniel L. Weinreb - Arlington MA
Assignee:
Progress Software Corporation - Bedford MA
International Classification:
G06F 1208
US Classification:
711119, 711144, 711145, 711152, 711207, 711208
Abstract:
An apparatus and method are provided for virtual memory mapping and transaction management in an object-oriented database system having permanent storage for storing data in at least one database, at least one cache memory for temporarily storing data, and a processing unit which runs application programs which request data using virtual addresses. When a data request is made, either for read or write, from a given client computer in a system, other client computers in the system are queried to determine if the requested data is cached and/or locked in a manner inconsistent with the requested use, and the inconsistent caching is downgraded or the transfer delayed until such downgrading can be performed.

US Patent:
7290113, Oct 30, 2007
Filed:
Sep 16, 2004
Appl. No.:
10/944444
Inventors:
Daniel L. Weinreb - Arlington MA,
Sam J. Haradhvala - Weston MA,
Assignee:
Progress Software Corporation - Bedford MA
International Classification:
G06F 12/10
G06F 15/16
US Classification:
711203, 709203
Abstract:
An apparatus and method provide virtual memory mapping and transaction management in an object-oriented database system having a database for permanently storing data, a cache memory for temporarily storing data, and a processing unit which runs application programs which request data using virtual addresses. The system performs data transfers in response to memory faults resulting from requested data not being available at specified virtual addresses and performs mapping of data in cache memory. The database includes pointers containing persistent addresses, which pointers are relocated between persistent addresses and virtual addresses. When a data request is made, either for read or write, from a client computer in a system, other client computers in the system are queried to determine if the requested data is cached and/or locked in a manner inconsistent with the requested use, and the inconsistent caching is downgraded or the transfer delayed until such downgrading can be performed.

Symbolic Language Data Processing System

View page
US Patent:
4922414, May 1, 1990
Filed:
Sep 8, 1987
Appl. No.:
7/078724
Inventors:
John T. Holloway - Belmont MA
David A. Moon - Cambridge MA
Howard I. Cannon - Lexington MA
Thomas F. Knight - Belmont MA
Bruce E. Edwards - Belmont MA
Daniel L. Weinreb - Somerville MA
Assignee:
Symbolics Inc. - Cambridge MA
International Classification:
G06F 900
US Classification:
364200
Abstract:
A symbolic language data processing system comprises a sequencer unit, a data path unit, a memory control unit, a front-end processor, an I/O and a main memory connected on a common Lbus to which other peripherals and data units can be connected for intercommunication. The system architecture includes a novel bus network, a synergistic combination of the Lbus, microtasking, centralized error correction circuitry and a synchronous pipelined memory including processor mediated direct memory access, stack cache windows with two segment addressing, a page hash table and page hash table cache, garbage collection and pointer control, a close connection of the macrocode and microcode which enables one to take interrupts in and out of the macrocode instruction sequences, parallel data type checking with tagged architecture, procedure call and microcode support, a generic bus and a unique instruction set to support symbolic language processing.
