Abstract: A database management system receives a new data table input to a database; and executes unique constraint determination processing of determining whether each comparison-subject value as each value registered in a target column in the new data table is different from each comparison reference value as each value registered in a target column in a stored data table in the database, and stores the new data table in a second database area different from a first database area storing the stored data table in the database when a determination result obtained in the unique constraint determination processing is true.

Abstract: A method for performing a live topological query includes, with a querying application, using a query graph to create a live topological query result from a database storing a full structure graph while not storing an entirety of the query result in a cache memory. The method further includes, in response to detecting a change within full structure graph, performing a calculation to determine whether the change is relevant to the query result, and notifying the querying application of a relevant change to the query result without relying on a fully cached copy of the query result.

Abstract: A query is received by a database server from a remote application server. The query encapsulates an on-the-fly calculation scenario that defines a data flow model that includes one or more calculation nodes. Thereafter, the database server instantiates the on-the-fly calculation scenario. The database server then executes the operations defined by the calculation nodes of the instantiated calculation scenario to result in a responsive data set so that the database server can provide the data set to the application server. Related apparatus, systems, methods, and articles are also described.

Abstract: A method and system for ranking query results on an electronic device includes the steps of obtaining a plurality of search results using a computer based on a query initiated by a user using a communications device. A ranking is determined of the search results based on a ranking technique using the computer.

The search results are ranked and sent to the communications device for display to the user.

Abstract: A monitor system transmits a request requesting event occurrence information to multiple node apparatuses, detects occurrence of an event on the basis of event occurrence information included in a response, calculates an index value of each of conclusions of multiple rules indicating corresponding relationship between one or more condition events and a conclusion, and generates, at a predetermined time point, a snapshot indicating an index value at that time point. When the monitor system receives a first response in reply to a first request, the monitor system updates the index value indicated by the snapshot generated in a period from a transmission date/time of the first request to a reception date/time of the first response, on the basis of the first response.

Abstract: A data storage array may be made up of several storage devices, each of which may contain array metadata that may allow portions of the storage array to be used. A system may have a file system manager that may receive and respond to file system commands and a storage device manager that may store data on the several storage devices. Array metadata defining where data is stored within the storage array is stored on each device within the array. A policy engine may identify data to be stored on the array and determine if the data contains array metadata or other types of data and may store the data on every device, devices having specific characteristics, two or more devices, or one device.

Abstract: A search engine may maintain a list of derived metadata. When an event occurs that requires updating a search index, the search engine can determine which metadata is derived metadata and take appropriate actions with respect to the derived metadata. For example, if a request is received to update the index for a particular object, the search engine may protect the derived metadata from change while updating the other metadata in the index. As another example, if a request is received to update the text content for the object, the search engine may change the text content and the derived metadata. By identifying derived metadata, the search engine can protect the derived metadata from change when a request is received that otherwise causes metadata to change and can change the derived metadata when a request is received that would otherwise not change the metadata portion of the index.
