A database management system, also called a DBMS, allows users to create a new database by specifying the logic structure of the data. For instance, the world of interest is represented as a collection of tables in relational DBMSs. This simple model is useful for many applications, and ...

In short, the foundational differences between LA and RA obstruct further optimization by combining these two systems at both the logical and implementation levels. RA operators on top of LA with GPU acceleration A unified data representation and operators are desirable for ML practitioners. One ...

Note:In this chapter the term "parallel server process" designates a process (or a thread, on NT systems) that is performing a parallel operation, as distinguished from the product "Oracle Parallel Server". Step 1: Tuning System Parameters for Parallel Execution ...
Parallel DML also is useful in OLTP systems to improve the performance of long-running batch jobs. Parallel DDL Oracle now has the ability to parallelize table and index creation. Statements such as the following can be parallelized: CREATE TABLE...AS SELECT...FROM CREATE INDEX ALTER INDEX ...

Path queries over labelled graphs are increasingly common in many applications. These include fraud detection [27], recommender systems [9] and social analysis [2] amongst others. Such a labelled graph has the formG=(V,E,LV,l), where each vertexvis annotated with a labell(v)∈LVfrom a ...
