Distributed architecture for paperwork imaging

摘要

The present invention provides a method and system for storage of data files, comprising notifying at least one local reference storage about storing and/or deleting a data file on a central data repository, depositing a reference element on the at least one local reference storage after notifying, requesting a deposited reference element from the local reference storage for demanding a data file contained in the central data repository, retrieving the demanded data file on submitting the reference element to the central data repository.

主权项

1. A method for providing image access across a computer network comprising a local reference storage, a client and a central data storage for storage of data files comprising a store logic unit, an image data base and an index data base, comprising:
administrating the data files and a reference element by store logic units by transferring the data files to the image data base and an index of a storage on the image data base to the index data base providing a reliable assignment of the data files to references and indexes, wherein the index data base maintains copies of searchable attributes of the data files for providing to notification interfaces connecting a plurality of local reference storages to an image database server; notifying the plurality of local reference storages about storing and/or deleting one of the data files on the central data storage triggered by the index database of the central data storage via the notification interfaces; depositing the reference element on the plurality of local reference storages after notifying by the central data storage; locating a requested data file of the data files of the central storage by the reference element in the local reference storage over a location interface of the local reference storage by the client; requesting the deposited reference element from the local reference storage by the client for demanding one of the data files contained in the central data storage; passing the requested deposited reference element back to the client by a local interface of the local reference storage; and retrieving the demanded data file on submitting the reference element to the central data storage via a retrieving interface of the central data storage, where requested image data is passed from the image data base via a retrieval interface to the client.
