One of the fundamental tasks that data warehouse (DW) administrator needs to perform during the physical design is to select the right indexes to speed up her/his queries. Two categories of indexes are available and supported by the main DBMS vendors: (i) indexes defined on a single table and (ii) indexes defined on multiple tables such as join indexes, bitmap join indexes, etc. Selecting relev...

black humor plays a crucial role in fulfilling langston hughes's anti-racist purposes as an integral notionin his poetry. accordingly, translation(s) of his poetry are to benefit from the same indexes onthe basis of equivalent effect principle. on this account, 33 black-humor-rich poems of hughes, translatedby ahmad shamloo, yaghma golruee and hassan fayyad, were selected to be analyzed contras...

SAS users are always interested in learning techniques related to improving data access. One way of improving information retrieval from a SAS data set or table is to create and use an index. An index consists of one or more columns that are used to uniquely identify each row within a table. Functioning as a SAS object containing the values in one or more columns in a table, an index may be def...

This paper presents a method for operational testing of a memristor-based look-up table (LUT) memory block. In the proposed method the deterioration of the memristors (as storage elements of a LUT), is modeled based on the reduction of the resistance range, a phenomenon well known as reported in the technical literature. A quiescent current technique is used to diagnose the memristors when dete...

There are several auxiliary pre-computed access structures that allow faster answers by reading less base data. Examples are materialized views, join indexes, B-tree and bitmap indexes. This paper proposes dimension-join, a new type of index especially suited for data warehouses. The dimension-join borrows ideas from several concepts. It is a bitmap index, it is a multi-table join and when bein...
