A system disclosed includes a temporal data warehouse and a platform independent temporal data warehouse load application operable to run on the system. The load application uses timestamp data from incoming data in conjunction with a relational algebra of set operators to identify and sequence net changes between the incoming data and data previously stored within the data warehouse. The load application loads the identified and sequenced net changes into the data warehouse with relatively little intrusion into normal operation of the data warehouse. Optimizations, including but not limited to, distinct partitioning of the workload into parallel streams are selectable via metadata.

Provided is a method, system, and program for processing a query including a query operation on a table derived from a set operation on two result tables. The query operation is performed on each result table separately to produce two intermediate result tables. The set operator is then applied to the two intermediate result tables to produce a final result table that is a same result table that would have been produced by performing the query operation on the table derived from the set operation performed on the two result tables.

A spreadsheet system stores objects and formulas in the cells of the spreadsheet, along with metadata tags. Each cell may contain multiple objects (such as a group of photos). Drag-and-drop user actions automatically change tags associated with the moved objects based on a formula stored in the target cell if a forcing semantics mode is active, or automatically change a formula stored in the target cell if a non-forcing semantics mode is active. A formula in a cell selects a set of objects and may include set operators such as union, intersection, and minus. The formula may also filter sets to select a subset based on specified tag attributes of objects. The display of the spreadsheet adaptively selects a subset of objects to render in a cell and appropriately scales photos for optimal viewing.

Plural key switches are arranged in two dimensions along X- and Y-coordinate axes, and an X-coordinate position of each of the key switches is associated with tone generation timing while a Y-coordinate position of each of the key switches is associated with a tone pitch. Storage section stores a music piece data set that includes tone generating data having data of tone pitches and tone generation timing associated with the key switches. In a repeat-section setting mode, a repeat-section setting section causes the plural key switches to function as setting operators and sets a repeat section of the music piece data set on the basis of the X-coordinate position of any operated one of the key switches. In reproduction of the stored music piece data set, a reproduction section repetitively reproduces the tone generating data of the music piece data set which are included in the set repeat section.

Non-linear functions to be used for automatically varying current values of parameters to be set, independently of each other, are prepared in corresponding relation to a plurality of parameter setting operator members, such as faders of a mixer. In response to an automatic setting instruction, such as a scene recall instruction, the current value of the parameter, to be set via each of the operator members, is caused to vary gradually toward a given target value with a characteristic based on a corresponding one of the non-linear functions. For example, the non-linear function is defined by a start offset for setting a delay in a start of the variation, and a fade time necessary for actually causing the parameter to vary up to the target value after the variation start. Processing of a predetermined type of event (e.g., GPI event) may be delayed to allow for a time delay that would result during execution of automatic setting processing of each parameter.
