A bounding volume is used to approximate the space an object occupies. If a more precise understanding beyond an approximation is required, the object itself is then inspected to determine what space it occupies. Often, a simple volume (such as an axis-aligned box) is used as bounding volume to approximate the space occupied by an object. But objects can be arbitrary, complicated shapes. So a simple volume often does not fit the object very well. That causes a lot of space that is not occupied by the object to be included in the approximation of the space being occupied by the object. Hardware-based techniques are disclosed herein, for example, for efficiently using multiple bounding volumes (such as axis-aligned bounding boxes) to represent, in effect, an arbitrarily shaped bounding volume to better fit the object, and for using such arbitrary bounding volumes to improve performance in applications such as ray tracing.

This disclosure relates generally to methods and systems for generating a textual summary from a tabular data. During the textual summary generation using conventional end-to-end neural network-based techniques, a numeric data present in the tables is encoded via textual embeddings.

Techniques herein optimally distribute graph query processing across heterogeneous tiers. In an embodiment, a computer receives a graph query to extract a query result (QR) from a graph in a database operated by a database management system (DBMS). The graph has vertices interconnected by edges. Each vertex has vertex properties, and each edge has edge properties. The computer decomposes the graph query into filter expressions (FE's). Each FE is processed as follows. A filtration tier to execute the FE is selected from: the DBMS which sends at least the QR to a stream, a stream evaluator that processes the stream as it arrives without waiting for the entire QR to arrive and that stores at least the QR into memory, and an in-memory evaluator that identifies the QR in memory. A translation of the FE executes on the filtration tier to obtain vertices and/or edges that satisfy the FE.
US11294892B2
A database-management system (DBMS) archives a record of a database table by updating the record's unique “Archived” field. This indicates that the record should be considered to have been archived despite the fact that the record has not been physically moved to a distinct archival storage area. When a query requests access to the table, the DBMS determines whether the query requests access to only archived data, only active data, or both. If both, the DBMS searches the entire table. Otherwise, the DBMS scans each record's Archived field to consider only those records that satisfy the query's requirement for either archived or active data. If the DBMS incorporates Multi-Version Concurrency Control (MVCC) technology, the DBMS combines this procedure with MVCC's time-based version-selection mechanism.
