摘要
Improved techniques for performing Matrix-Related operations (e.g., Matrix Multiplication, Matrix Transpose) in Relational Database systems are disclosed. Techniques provide Matrix Data Sets for performing Matrix-Related operations in Relational Databases more efficiently than conventional techniques. By way of example, Matrix Data can be partitioned such that data each partition can be processed directly in a cache memory of a processor thereby reducing the need for copying data as it is conventionally done in Relational Databases. In addition, database queries involving Matrix-Related operations can be optimized for a Relational Database by providing Matrix Operations that can be directly used as declarative statements in a Database Query language (e.g., SQL). Furthermore, database query optimizers of a Relational Database can be further enhanced by allowing them to consider Matrix Algebra, as well as other opportunities in processing Matrix-related operation, possibly in connection of one or more the facets of the improved techniques.
