Abstract:

In a database, a database manager can generate a view, which, in concept, is a subset of the database, which is placed outside the database for use without disturbing the database, and without disturbance by others using the database. The subset, or view, can be understood as a collection of rows, or tuples, of data copied from the database. With views existing, multiple copies of data within the database now exist: the original in the database, and copies in the views. If one of these is changed, without corresponding changes made in the others, then inconsistencies occur, which cannot be tolerated. Under the invention, when a user seeks a lock on a view, indicating that a change may be imminent, the invention locks a superset of the tuples in the database from which the view is derived. A superset is a set which contains the set of tuples of the view, plus possibly others. Thus, more tuples are locked than strictly necessary.

International Classification:

US Classification:

707203

Abstract:

In a database, a database manager can generate a view, which can be considered as a subset of the database, and which is placed outside the database for use without disturbing the database. However, if the database changes, the views will not reflect those changes, because the views are separate from the database. To solve this problem, a process called "refreshing" keeps the views consistent with the data within the database. But different refreshing approaches are used: some views require immediate refreshing when the database changes, other types can be refreshed at later times, and still other types can be refreshed at different times and intervals. The invention presents a system which keeps data consistent among the views and the database, despite the different times of refreshing undertaken.

International Classification:

US Classification:

395602

Abstract:

A technique for efficiently joining multiple large tables in a database system with a processor using a small main memory. The technique utilizes a join index and minimizes the number of Input/Output operations while maximizing the use of the small main memory through a buffer allocation process. Three embodiments of the technique are described all of which use the parallel-merge operation. The first technique, slam-join, is for joining two tables and does not require any pre-allocation of buffers to perform the join operation. The second technique, multi-slam-join, is for joining three or more tables and adds the parallel-merge technique to a join technique which partitions memory to be used for an efficient join operation. The third technique, called parallel-join, processes each input table completely independently using the parallel-merge technique. The parallel-merge technique identifies the lowest value from multiple files and orders all the values from lowest to highest.

US Classification:

403267, 156305, 156 94, 295271

Abstract:

The described embodiments relate generally to methods to enhance cosmetic surfaces of friction stir processed parts. More specifically a method for applying cold spray over a weld line generated by the friction stir processing is disclosed. Methods are also disclosed for blending the cold spray applied over the weld line in with a cosmetic surface portion of friction stir processed parts. In some embodiments cold spray can be used to on its own to create a cosmetic joint between various parts. Structural joints between first and second substrates may also be formed via solid state deposition. Such joints may be strengthened through use of a hidden weld, mechanical interlocking between the substrates, and/or coupling via fasteners.
