ABSTRACT The majority of computer information system developments utilize an object oriented technology such as java to construct the application interface and at the same time relying on the relational database to store the enterprise data. Connecting these two 

Data Security in Relational Database Management System

ABSTRACT Proving ownerships rights on outsourced relational database is a crucial issue in today's internet based application environments and in many content distribution applications. Here mechanism is proposed for proof of ownership based on the secure 

Automating Relational Database Schema Design for Very Large Semantic Datasets
free download

ABSTRACT Many semantic datasets or RDF datasets are very large but have no pre-defined data structures. Triple stores are commonly used as RDF databases yet they cannot achieve good query performance for large datasets owing to excessive self-joins. Recent research 

Survey on Aggregation Operators and Functions of Relational Database Management System
free download

ABSTRACT A relational database is a collection of data items organized as a set of formally- describe d table s from which data can be accessed or reassembled in many different ways without having to reorganize the database tables. Various aggregation functions are 

A STUDY ON THE TRANSLATION MECHANISM FROM RELATIONAL-BASED DATABASE TO COLUMN-BASED DATABASE
free download

ABSTRACT Lately, column-based database (CDB) has been considered as a standard solution dealing with the big data. But there is no standard translation mechanism mapping from Relational Database (RDB) to CDB. In this paper, we proposed a mechanism 

Development of a Relational Database on Catalysis Relevant Data

ABSTRACT A relational data base for thermo-chemical material parameters is presented. This data base is motivated by the recommendations of AVT-136 in order to systematically assess differences eg in recombination coefficients measured with different 

Self-Constructing Fragile Watermark Algorithm for Relational Database Integrity Proof
free download

ABSTRACT Database watermarking has gained a keen interest of researchers since the coin was tossed by Agarwal. Since then many approaches have been adopted to protect the copyright of relational databases. The concept was proposed after getting inspiration from 

Cost based Graphical Vertical Fragmentation in Relational Database
free download

ABSTRACT In a distributed database environment, query processing heavily depends upon locality of the requested data at the query site. When relations are vertically fragmented, data locality can be improved significantly since the fragments can be replicated flexibly without 

A novel method for improving the efficiency of automatic construction of ontology from arelational database
free download

With the development of the semantic web, ontology is playing an increasingly important role in many research areas such as semantic interoperability and knowledge base. However, constructing ontology manually is complicated and needs the supports of 

A Comparative Study Between Two Types of Database Management Systems: XML-EnabledRelational and Native XML
free download

ABSTRACT As there is an increase use of XML documents to store and exchange data over the web, there is a great need for a database management system able to store, retrieve and manipulate XML data with an efficient manner, here the XML database (XML DB) can 

An Encryption algorithm for providing security to the relational database

A Tool for Generating Relational Database Schema from EER Diagram
free download

ABSTRACT Database design is an important activity in software development. EER diagram is one of diagrams, which is used in database design because EER diagram is a graphical representation and easy to understand between users and developers. Relational 

Risk Assessment for Relational Database Schema-based Constraint Using State Machine Diagram
free download

ABSTRACT Information is a critical asset of an organization. This is why reducing the chance of data loss must be a primary concern. This research focuses on the risk assessment issue in physical level of data implementation, which includes identifying risk factors and 

Towards Ontology Development Based On Relational Database
free download

ABSTRACT Ontology is defined as the formal explicit specification of a shared conceptualization. It has been widely used in almost all fields especially artificial intelligence, data mining, and semantic web etc. It is constructed using various set of 

Semantic query in a relational database using a local ontology construction
free download

The use of a structured query formulation language is one way to retrieve information in information management systems. Formulated queries allow the selection of data under particular constraints. In contrast to menu driven or query by example (QBE) information 

The Teaching of Relational On-Line Analytical Processing (ROLAP) in Advanced DatabaseCourses
free download

ABSTRACT One of the problems with teaching ROLAP and Data Warehousing in database systems courses is the difficulty of providing practical exposure of the topics to the students. The approach taken in this work is intended to help students apply the knowledge learnt 

Generating of RDF graph from a relational database using Jena API
free download

ABSTRACT a great part of the existing data on the web is stored in relational databases (RDB). However, the transition from the traditional web to Semantic web requires new structuring of these data. In this context we propose a method which allows automatic extraction of 

LANLI: A Natural Language Interfacing Tool for Relational Database Query Generation
free download

ABSTRACT Most conventional databases in use today are based on the relational model. Values in a relation are taken from a finite set of strictly typed domain. Each relation in the database represents a proposition and each record in a relation is a statement such that it

Lab 3: SQL and Data Indexing Techniques in Relational Database
free download

When accessing a table, POSTGRESQL normally reads from the beginning of the table to the end, looking for relevant rows. With an index, it can quickly find specific values in the index, and then go directly to matching rows. In this way, indexes allow fast retrieval of 

Cost-based optimization of graph queries in relational database management systems
