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

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

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

Seminar on Relational Calculus


Comes in two flavours: Tuple relational calculus (TRC) and Domain relational calculus (DRC).
Calculus has variables, constants, comparison ops, logical connectives and quantifiers.
TRC: Variables range over (i.e., get bound to) tuples.
DRC: Variables range over domain elements (= field values).
Both TRC and DRC are simple subsets of first-order logic.
Expressions in the calculus are called formulas. An answer tuple is essentially an assignment of constants to vari ....etc

Keys
SuperKey
a set of attributes whose values together uniquely identify a tuple in a relation
Candidate Key
a superkey for which no proper subset is a superkey…a key that is minimal .
Can be more than one for a relation
Primary Key
a candidate key chosen to be the main key for the relation.
One for each relation
Keys can be composite
