摘要:
Methods, systems and related products for collaborative exchange of healthcare data using a computer network are configured to: (a) receive a participating Subscriber's request for publication of selected clinical data from participating Publishers that have respective Publisher repositories of clinical data; (b) determine whether respective Publishers approve publication of their clinical data for the selected clinical data and the requesting Subscriber; and (c) electronically forward the selected clinical data from those participating Publishers that approve publication of the requested selected clinical data to the requesting Subscriber.
摘要:
A method for managing concurrency using a serializing token as a supplement to locks for accessing the same page by different processes and ensuring coherence between data caches and a shared access backing store supporting the processes defined onto multiple processors. A shared lock and a new token are issued by a local lock manager (LLM) and local cache manager (LCM) in response to a page read request from a process. An exclusive lock, an invalidation of all cache resident copies of the page, a cache write through to backing store of the changed page, a copyback of a new token, and lock release are responsive to a page write/update request from a process where the token issued to the process during a prior request matches the token stored with a cache resident copy of the page. Otherwise, a write request fails and the process must first issue a read request to the page of interest.
摘要:
A method to manage the access of data or pages mapped into a very large virtual external address space through a cache without disturbing the logical view of the data and without having to assign physical or real backing store to said logical view. A data cache is used in which pages are indexed according to a logical address intermediate to their virtual address and their physical location in external storage. Pages common to two or more files are updated in place in the cache, while pages bound to only one file are shadow copied.

A Publisher source of healthcare data is configured to communicate with an Internet-based data sharing system, the Publisher comprising a Publisher Gateway configured to electronically receive patient data from a plurality of data input sources, automatically correlate data from the plurality of input sources associated with respective patients into respective electronic patient data records having electronically searchable data fields, and electronically store the patient data records in a Publisher database.

Methods, systems and related computer products for providing entitlement controlled levels of collaborative exchange of data using a computer network of Subscribers and Publishers, are configured to: (a) define a set of different privacy levels, each privacy level having associated data sharing parameters that control a participating Publisher's ability to send and a participating Subscriber's ability to receive content specific data; and (b) provide an electronic privacy level register that defines the different data sharing parameters for each of the different privacy levels and identifies an associated at least one privacy level for each participating Subscriber and Publisher.

摘要:
A computer implemented method for robustly copying pages to system managed storage in order to maintain data in a consistent state and in order to provide continuous access availability of the pages to executing applications. The method achieves data consistency by atomically shadow copying application referenced pages and amending directories in a failure independent medium on (1) an access path interrupt as well as on (2) a page update basis. Availability is enhanced by duplexing the pages and directories as part of the atomic shadow copying step.
