Abstract: The SQL compiler and SQL executor in a database management system are extended to process queries requiring streaming mode processing of data stored in a table. A scan operator performs table access functions during execution of the streaming mode query. The scan operator first performs an initial scan to access rows in a specified database table, and then performs a delta scan to access new rows added to the table, as well as rows modified by other queries. The scan operator continues to process new data added to the table until the initiating user or application closes the associated cursor. A set of data structures are provided to keep track of active scan operators, including a session control block that includes fields for keeping track of whether the scan operator is performing an initial scan or a delta scan. The session control block also includes, for streaming mode scan operators, a delta scan list of new and modified rows to be processed in the delta scan.

Abstract: Disclose is a system, method, and program for accessing files maintained in a server that is capable of being accessed over a network. A request is received for a file maintained in the server. A determination is then made as to whether a copy of the requested file is stored in a storage system. The system then determines a delay time associated with retrieving the copy of the requested file from the storage system after determining that the storage system includes the copy of the requested file. A determination is then made as to whether the delay time exceeds a maximum delay time. The system retrieves the requested file from the storage system to return to the request after determining that the delay time does not exceed the maximum delay time. Alternatively, the system retrieves the requested file from the server over the network to return to the request after determining that the delay time exceeds the maximum delay time.

Agent restoring unit restores the agent of MPU code to the original agent, and stores it in the memory area.

Abstract: A system and method for organizing raw data from one or more sources uses an improved mechanism for identifying duplicate data between fields (e.g., columns) in the databases. The fields may be similar fields within a single database or similar or identical fields within a pair of databases and as organized as arrays or field vectors. The present invention sorts each of the field vectors and if necessary, partitions them by common value. A number of comparisons required to identify the duplicate data between the field vectors is reduced by feeding back a difference between the compared values. This difference is used to adjust indices into the field vectors for subsequent comparison.

Abstract: Similarity measure has been one of the critical issues for successful content-based retrieval. Simple quadratic forms of distance is inadequate as it does not necessary correspond to perceived similarity nor is it adaptive to different applications. This patent application describes a new sequential query processing algorith for evaluating content-based composite object queries. The composite objects consist of spatial and temporal arrangements of simple objects. The simple objects are defined in terms of spatial, temporal, feature and semantic attributes. The query method defines a process for executing a best-first search for the matches to the query, while providing a flexible framework for broadening the search space as required. The query method guarantees that there are no false dismissals of the candidate composite objects.

Abstract: A method of performing a transaction on a database. A number of transactions are available to be performed on said database. At least one of said transactions may only be performed if corresponding requirements are fulfilled, wherein the fulfillment of said requirements depends on the prior successful termination of at least one other transaction. Then, said at least one of said transactions is invoked. Depending on stored information relating to prior successful terminations of transactions it is then checked whether said corresponding requirements are fulfilled. If said requirements are fulfilled, said transaction is performed. Then, after a successful termination of said transaction, an information relating to said successful termination is stored.

Abstract: The present invention provides a method for transferring data between source and target databases in a computer system that can adapt to changes in the schema of the source database and/or target database. This adaptability is achieved by determining the intersection of the source and target database schemas prior to a transfer of data between the databases. Since the intersection is determined prior to a transfer, changes in the schema of the source and/or target database are automatically accommodated. In one embodiment, the method includes the ability to specify the desired frequency with which data is to be transferred between source and target databases. The method, which is implemented as a computer program, is also capable of operating in a computer system in which other tasks are competing for processor time.
