A method and system for creating a series of online snapshots for recovery purposes. A series of concurrent, overlapping snapshots (e.g., file snapshots or database file snapshots) may be created over a user-specified time interval at a user-specified frequency. Monitoring for a recovery indication may occur during the user-specified time interval. Once it is established that a "recovery" is necessary, a snapback procedure may be implemented to iteratively restore one or more pre-update snapshot images. Between restore iterations, testing to determine if the problem still exists may occur. When the testing of the data results in a determination that the problem is resolved, no further restores are necessary.

A method and system for forming a data table in memory on an end user system. The data table forming a library index of storage locations to electronic digital content in memory. The method consists of retrieving an encrypted file from storage. The file has a beginning, an end and a trailer section located just prior to the end. The file is read from the end a predetermined distance to verify if an identifier is present. Reading and decrypting the trailer section from the file read. Determining if there are any updates in the trailer section. In the case there are no updates in the trailer section then decrypting the reference table containing one or more data table location indicators for data items with the first decrypting key. Next, decrypting one or data items with the first decrypting key. Populating the data table with data items at locations specified in the reference table.

In processing system that includes a processing element communicatively coupled to a storage system for storage of database files (35) managed by a database management system (34) having a transaction management facility (36), file access operations from application processes are intercepted and checked to determine if the operation is from a non-transactional process, and if so, whether an automatic transaction should be started for the operation.

The system and method of the present invention provide integrated or embedded components, for electronic (or other) products, each operable to securely store and selectively provide access to, a unique ID (UID) previously assigned to its corresponding specific product, where the UID of each product is registered with one or more particular UID registration centers over at least one communication network, and associated with one or more data records stored in a corresponding database file at the particular UID registration center, the data records being inclusive of information related to the product, the product purchase history, current ownership, etch, and wherein one or more authorized parties may subsequently advantageously utilize at least one UID (and optionally a verifier) to access, verify, edit, transfer, transmit, and / or otherwise manage at least one information item related to the one or more corresponding registered products in their UID registration center database file. Also provided is an optimized process for verifiable transfer of ownership rights between a product's authorized owner and intended recipient, the transfer process being implemented over at least one communication network with graphical user interfaces provided for each party, where the transfer of ownership rights involves association of the product's UID with the receiving party's data record and confirming ownership transfer, and optional transfer of additional product-related information from the former product owner to the current recipient.

A system and method are disclosed for utilizing compression in database caches to facilitate access to database information. In contrast with applying compression to the database that is stored on disk, the present invention achieves performance advantages by using compression within the main memory database cache used by a database management system to manage data transfers to and from a physical database file stored on a storage system or stored on a networked attached device or node. The disclosed system and method thereby provide a significant technical advantage by increasing the effective database cache size. And this effective increase in database cache size can greatly enhance the operations-per-second capability of a database management system by reducing unnecessary disk or network accesses thereby reducing data access times.
