On-line Analytical Processing (OLAP) has become a fundamental component of contemporary decision support systems and represents a means by which knowledge workers can efficiently analyze vast amounts of organizational data. Within the OLAP context, one of the more interesting recent themes has been the computation and manipulation of the data cube, a relational model that can be used to represent summarized multi-dimensional views of massive data warehousing archives.

Over the past five or six years a number of efficient sequential algo ....etc

Fragile Watermarking Scheme for Relational Database


Existing System

Database integrity has long been considered one of the three pillars in the database security arena, together with authentication and authorization (access control).

But the research of database integrity mainly focuses on semantic integrity constraints, which are rules defining the correct states of the database. Traditional approaches use verification information such as message authentic ....etc

Abstract
In this paper the various tactics for query processing in INGRESS are empirically evaluated on a test bed of sample queries.
1. Introduction
In Ref. 5 we presented a general strategy for query processing known as decomposition, which had been designed for the nonprocedural query language QUEL2 and was in the process of being implemented in the relational database management system INGRESS. 4 In this approach the problem of dealing with a multi-relational query is separated into two
stages. First, a query which refere ....etc
