This document summarizes a research paper on reengineering relational databases to object-oriented databases. It discusses developing an integrated environment that maps a relational schema to an object-oriented schema without modifying the existing relational schema. The proposed system architecture has two major components - one for mapping the relational schema to an object-oriented schema, and another for mapping relational data to objects. The schema mapping process is two-phased - the first phase transforms the relational schema, and the second phase extracts object-oriented structures. The system aims to allow existing applications and data in a relational database to be accessible from object-oriented programs.

Immune-Inspired Method for Selecting the Optimal Solution in Semantic Web Ser...IJwest
The increasing interest in developing efficient and effective optimization techniques has conducted researchers to turn their attention towards biology. It has been noticed that biology offers many clues for designing novel optimization techniques, these approaches exhibit self-organizing capabilities and permit the reachability of promising solutions without the existence of a central coordinator. In this paper we handle the problem of dynamic web service composition, by using the clonal selection algorithm. In order to assess the optimality rate of a given composition, we use the QOS attributes of the services involved in the workflow as well as, the semantic similarity between these components. The experimental evaluation shows that the proposed approach has a better performance in comparison with other approaches such as the genetic algorithm.

Converting UML Class Diagrams into Temporal Object Relational DataBase IJECEIAES
Number of active researchers and experts, are engaged to develop and implement new mechanism and features in time varying database management system (TVDBMS), to respond to the recommendation of modern business environment.Time-varying data management has been much taken into consideration with either the attribute or tuple time stamping schema. Our main approach here is to try to offer a better solution to all mentioned limitations of existing works, in order to provide the nonprocedural data definitions, queries of temporal data as complete as possible technical conversion ,that allow to easily realize and share all conceptual details of the UML class specifications, from conception and design point of view. This paper contributes to represent a logical design schema by UML class diagrams, which are handled by stereotypes to express a temporal object relational database with attribute timestamping.
Semantic Annotation Framework For Intelligent Information Retrieval Using KIM...dannyijwest
Due to the explosion of information/knowledge on the web and wide use of search engines for desired
information,the role of knowledge management(KM) is becoming more significant in an organization.
Knowledge Management in an Organization is used to create ,capture, store, share, retrieve and manage
information efficiently. The semantic web, an intelligent and meaningful web, tend to provide a promising
platform for knowledge management systems and vice versa, since they have the potential to give each
other the real substance for machine-understandable web resources which in turn will lead to an
intelligent, meaningful and efficient information retrieval on web. Today,the challenge for web community
is to integrate the distributed heterogeneous resources on web with an objective of an intelligent web
environment focusing on data semantics and user requirements. Semantic Annotation(SA) is being widely
used which is about assigning to the entities in the text and links to their semantic descriptions. Various
tools like KIM, Amaya etc may be used for semantic Annotation.

Formal Models for Context Aware ComputingEditor IJCATR
Context-aware computing refers to a general class of mobile systems that can sense their physical environment, and
adapt their behavior accordingly. In this paper we seek to develop a systematic understanding of context-aware computing by
constructing a formal model and notation for expressing context-aware computations. This discussion is followed by a
description and comparison of current context modeling and reasoning techniques.
Community detection of political blogs network based on structure-attribute g...IJECEIAES
Complex networks provide means to represent different kinds of networks with multiple features. Most biological, sensor and social networks can be represented as a graph depending on the pattern of connections among their elements. The goal of the graph clustering is to divide a large graph into many clusters based on various similarity criteria’s. Political blogs as standard social dataset network, in which it can be considered as blog-blog connection, where each node has political learning beside other attributes. The main objective of work is to introduce a graph clustering method in social network analysis. The proposed Structure-Attribute Similarity (SAS-Cluster) able to detect structures of community, based on nodes similarities. The method combines topological structure with multiple characteristics of nodes, to earn the ultimate similarity. The proposed method is evaluated using well-known evaluation measures, Density, and Entropy. Finally, the presented method was compared with the state-of-art comparative method, and the results show that the proposed method is superior to the comparative method according to the evaluations measures.
A spatial data model for moving object databasesijdms
Moving Object Databases will have significant role in Geospatial Information Systems as they allow users
to model continuous movements of entities in the databases and perform spatio-temporal analysis. For
representing and querying moving objects, an algebra with a comprehensive framework of User Defined
Types together with a set of functions on those types is needed. Moreover, concerning real world
applications, moving objects move along constrained environments like transportation networks so that an
extra algebra for modeling networks is demanded, too. These algebras can be inserted in any data model if
their designs are based on available standards such as Open Geospatial Consortium that provides a
common model for existing DBMS’s. In this paper, we focus on extending a spatial data model for
constrained moving objects. Static and moving geometries in our model are based on Open Geospatial
Consortium standards. We also extend Structured Query Language for retrieving, querying, and
manipulating spatio-temporal data related to moving objects as a simple and expressive query language.
Finally as a proof-of-concept, we implement a generator to generate data for moving objects constrained
by a transportation network. Such a generator primarily aims at traffic planning applications.
An Introduction to Architecture of Object Oriented Database Management System and how it differs from RDBMS means Relational Database Management System
Improved Presentation and Facade Layer Operations for Software Engineering Pr...Dr. Amarjeet Singh
Nowadays, one of the most challenging situations for
software developers is the presence of a mismatch between
relational database systems and programming codes. In the
literature, this problem is defined as "impedance mismatch".
This study is to develop a framework built on innovations
based on the existing Object Relational Mapping technique to
solve these problems. In the study, users can perform
operations for three different database systems such as
MsSQL, MySql and Oracle. In addition, these operations can
be done within the framework of C# and Java programming
languages. In this framework, while the developers can define
database tables in the interface automatically, they can create
relations between tables by defining a foreign key. When the
system performs these operations, it creates tables, views, and
stored procedures automatically. In addition, entity classes in
C# and Java for tables and views, and operation classes for
stored procedures are created automatically. The summary of
the transactions can be taken as pdf file by the framework. In
addition, the project can automatically create Windows
Communication Foundation classes to facilitate the handling
of database elements created and the interfacing operations, as
well. This framework, which supports distributed systems, can
be downloaded at this link.
The advent of Big Data has seen the emergence of new processing and storage challenges. These challenges are often solved by distributed processing. Distributed systems are inherently dynamic and unstable, so it is realistic to expect that some resources will fail during use. Load balancing and task scheduling is an important step in determining the performance of parallel applications. Hence the need to design load balancing algorithms adapted to grid computing. In this paper, we propose a dynamic and hierarchical load balancing strategy at two levels: Intrascheduler load balancing, in order to avoid the use of the large-scale communication network, and interscheduler load balancing, for a load regulation of our whole system. The strategy allows improving the average response time of CLOAK-Reduce application tasks with minimal communication. We first focus on the three performance indicators, namely response time, process latency and running time of MapReduce tasks.

IMPLEMENTATION OF DYNAMIC COUPLING MEASUREMENT OF DISTRIBUTED OBJECT ORIENTED...IJCSEA Journal
Software metrics are increasingly playing a central role in the planning and control of software development projects. Coupling measures have important applications in software development and maintenance. Existing literature on software metrics is mainly focused on centralized systems, while work in the area of distributed systems, particularly in service-oriented systems, is scarce. Distributed systems with service oriented components are even more heterogeneous networking and execution environment. Traditional coupling measures take into account only “static” couplings. They do not account for “dynamic” couplings due to polymorphism and may significantly underestimate the complexity of software and misjudge the need for code inspection, testing and debugging. This is expected to result in poor predictive accuracy of the quality models in distributed Object Oriented systems that utilize static coupling measurements. In order to overcome these issues, we propose a hybrid model in Distributed Object Oriented Software for measure the coupling dynamically. In the proposed method, there are three steps such as Instrumentation process, Post processing and Coupling measurement. Initially the instrumentation process is done. In this process the instrumented JVM that has been modified to trace method calls. During this process, three trace files are created namely .prf, .clp, .svp. In the second step, the information in these file are merged. At the end of this step, the merged detailed trace of each JVM contains pointers to the merged trace files of the other JVM such that the path of every remote call from the client to the server can be uniquely identified. Finally, the coupling metrics are measured dynamically. The implementation results show that the proposed system will effectively measure the coupling metrics dynamically.

ME/R model: A New approach of Data Warehouse Schema Designidescitation
In this paper we pursue schema design for data
warehouses in the spirit of classical database design, organized
as a sequence of requirement analysis and specification to
collect user requirements, conceptual design to model the
data warehouse as a multidimensional database independently
from implementation issues, logical design to transform the
conceptual data warehouse schema into the target data model,
and physical design to maximize performance with respect to
a target database system.
Activity Context Modeling in Context-AwareEditor IJCATR
The explosion of mobile devices has fuelled the advancement of pervasive computing to provide personal assistance in this
information-driven world. Pervasive computing takes advantage of context-aware computing to track, use and adapt to contextual
information. The context that has attracted the attention of many researchers is the activity context. There are six major techniques that
are used to model activity context. These techniques are key-value, logic-based, ontology-based, object-oriented, mark-up schemes and
graphical. This paper analyses these techniques in detail by describing how each technique is implemented while reviewing their pros
and cons. The paper ends with a hybrid modeling method that fits heterogeneous environment while considering the entire of modeling
through data acquisition and utilization stages. The modeling stages of activity context are data sensation, data abstraction and
reasoning and planning. The work revealed that mark-up schemes and object-oriented are best applicable at the data sensation stage.
Key-value and object-oriented techniques fairly support data abstraction stage whereas the logic-based and ontology-based techniques
are the ideal techniques for reasoning and planning stage. In a distributed system, mark-up schemes are very useful in data
communication over a network and graphical technique should be used when saving context data into database.
This study mainly focuses on how object-oriented analysis makes compatible with newly develop or other existing business computing application in a better way. This study also focuses on the modeling of the exact procedure or near to the exact procedure within its application domain which may model by using different objects class. Objects are basically structured into different classes of objects which are generally related to behaviors and characteristics. These methodologies may use different generalization, classification, and different aggregation as a structure object assemblies for the target actions like services or activities which are related to the objects. There are numerous misconceptions related to object oriented analysis which are required to address when we consider the use of any object-oriented method. In this paper try to represent different advantages and various application of the UML in the field of automatic system analysis and modeling. The platform presented here is a comprehensive range of the different UML templates with all other required information.

1. Introduction
Relational database management systems (RDBMS) provide a variety of tools and services for data
management. There are many tools that interface with RDBMSs to enable end-users to carry out reporting,
querying, and other data analysis activities easily. On the other hand, object -oriented programming has been gaining
wide acceptance in the programming community as a paradigm for developing comp lex applic ations that are easy to
extend and maintain. Developers typically implement object-oriented applications using object-oriented programming
languages such as C# and Java. These applications use a schema made up of object classes and relationships between
those object classes. Each object has a set of attributes. The value of an attribute could be another object itself, thus
giving rise to complex objects. The main problem arises when the data corresponding to such objects are persistent in a
relational database. The problem is due to incompatibility between relations and objects. At first, a solution for this
problem may seem to be to use an ODBMS instead of RDBM S. If an ODBMS is managing the persistent data, the
objects do not lose their structure after the application stores them in the object database. Moving to an ODBMS might
mean throwing away all of the old (“legacy") data and applications. Most users of databases will not accept such a
solution. They wish to be able to run their existing applications on existing databases and have access to the same data
fro m object-o riented programs, too. Therefore, we need special techniques to convert the data that is residing in a
relational database to a format that is suitable for access and manipulat ion by object-oriented applications.
2. Literature review
The problem of migrating data is present in almost every application development process, such as data
warehousing and application integration. The algorithm imp lements process of migrat ing data involves firstly the
mapping between the structures of the source and target databases and secondly the mig ration of the data fro m the source
to the target [3].
The problem is how to effectively migrate existing RDBs, as a source, into OODB/ORD B/XM L, as targets, and
what is the best way to enrich and maintain RDBs’ semantics and constraints in order to meet the characteristics of the
three targets? Existing work does not appear to provide a complete solution for more than one target database. We tackle
this question by proposing a solution for migrat ing an RDB into the three targets based on available standards [4].
One general approach to migrate to object technology is to divide the process into two phases, where the first one
transforms the relational into an object-oriented schema and the second one migrates the data into the object -oriented
database system discussed in [5].
The goal of re-engineering is to mechanically reuse past development efforts particular relat ional databases
(RDBs).in order to reduce maintenance expense and improve software flexibility [4]. The object behavior of eight Java
programs including four real-world Java object oriented database management systems and a counterpart of four real-
world Java programs are analy zed in [6]. A technique for transferring query optimizat ion techniques, developed for
relational databases, into object Databases. This technique for ODM G database schemas defined in ODL and object
queries exp ressed in OQL. The object schema is represented using a logical representation (Datalog) [7].
3. Analysis of problem
Moving to an ODBMS might mean throwing away all of the old (“legacy") data and applications. Most users of
databases will not accept such a solution. They wish to be able to run their existing databases and have access to the

same data fro m object-oriented program.
Thus we need to implement a system that builds an understanding of a given conventional database by taking
these characteristics as input and produces the corresponding object-oriented database as output. Finally, we handle the
migrat ion of data fro m the conventional database to the constructed object -oriented database.
The Primary object ives of proposed work are as follows.
1. Study the automatability of the relational-to-OO schema mapping process.
2. Define an interactive process for mapping an existing relat ional schema to an object -oriented schema.
3. Develop an interactive system to validate proposed work
4. System architecture
The architecture contains two major components needed for fulfilling our aim. The first component deals with
mapping the relational schema to an object-oriented schema. The second component deals with the mapping between the
relational data and objects.

Schema Mapping
The static schema mapp ing process is a two-phase process. In the first phase, the relational schema is adjusted and
transformed into another virtual relational schema that has some specific properties . In the second phase, object-oriented
structures are ext racted fro m the virtual relational schema.
Figure 2.Two Phases of Static Schema Mapping
Phase I: Adjusting the Rel ati onal Schema
There are four specific aspects that are addressed during phase one. They are as follo ws:
Step 1. Eliminate 2NF relat ions and replace them with new 3NF virtual relations.
Step 2. Create virtual subclass relations for widow super class relations
Step 3. Create virtual superclass relations for orphan subclass relations.
Step 4. Eliminate mu lti-valued attributes and replace them with new 3NF virtual relations.
Phase II: Generation of the Object Schema
At the end of phase one of the schema mapping process, the relational schema has been adjusted to a form in wh ich
schema mapping rules can be applied unifo rmly.
Step1. Identifying Object Classes:
Those relations that correspond to object- classes must be identified.
Step2. Identifying Relationshi p:
There are three types of relationships that can be represented in an object model. They are associations, generalizat ions
specializations, and aggregations.
Identifying each of these constructs constitutes a step in the mapping process.
Identi fying Associations. Since the object model allo ws associations to be modeled as classes, we must either establish
a simple association between two object classes or identify relat ionships where the associations are modeled as
classes.
Identi fying Inheritance. Inheritance structures capture the generalizat ion and specializat ion relations hips between
object classes that have been identified so far.

Identi fying Aggregation. The aggregation relat ionship models the co mposition of one object with other objects. such
complex object must be identified. The difference between aggregation and association is that the former involves
existence dependence of the sub-object on the whole object. For example, a door object, wh ich is a part-of" of a car
object, cannot exist if the car object does not exist. On the other hand, the enrollment of a student in a course is
an association rather than an aggregation because the student and course objects can exist independent of each other.
Step 3. Es tablishing Cardinalities : Establishing the card inalities of associations is important in o rder to facilitate
the imp lementation of the object schema in a g iven programming language (e.g., C#). The d ifferent possible
cardinalities are one-one, one-many, and many-many.
5. Conclusion
We will imp lement the architecture having two phases in the data mapping process; one mapping procedure
specifies the data mapping between the original relat ional schema and the adjusted relational schema. The second
mapping procedure specifies the data mapping between the adjusted relational schema and the object schema. The data
mapping procedures have been specified using relat ional algebra for each new virtual relation that is created
during phase one of the static schema mapping.
