The recent trends in the computer industry are the one
and only thing i.e., web services. Because of the common
availability and open technologies web services are relevant to
all. Service-oriented architecture (SOA) helps organizations to
transform their business processes for high performance by
simplifying the underlying information systems. The most
challenging aspect of building successful software applications is
clearly understanding and specifying the requirements that an
application must satisfy. Use case modeling is an increasingly
popular approach for identifying and defining requirements for
software applications of all types. Use cases describe the
behavior of the system as its users interact with it. This approach
helps to place the software requirements in the framework of a
user doing some useful work with the system. This type of
approach helps to map software requirements to the relevant enduser business processes, a very powerful concept. This paper
presents how the relationship between use case model and
Service oriented architecture.

A SERVICE ORIENTED DESIGN APPROACH FOR E-GOVERNANCE SYSTEMSijitcs
Today electronic Governance (E-governance) is no more a buzzword but a reality as countries all over the
worldwide have shown interest in harnessing governance with state-of-the-art information and
communication technology(ICT), in order to foster better governance. However, the inherent complexities
of E-governance systems remain as a challenge for the architects to develop large scale, distributed, and
interoperable E-governance applications. Besides this the dynamic nature of such applications further
complicates the system design. In this paper, we present a design approach based on the service oriented
paradigm for building E-governance systems. We also formalize concepts like service environment, service
composition, and service collaboration which are some of the important ingredients of our design
approach. In the sequel we highlight the suitability of our approach through some E-governance service

Contemporary research challenges and applications of service oriented archite...Dr. Shahanawaj Ahamad
Service Oriented Architecture (SOA) is distributed architectural framework that provides service-based
solutions for improving the effectiveness of enterprise’s IT infrastructure. In this framework, technical and
business processes are implemented as services. A service is an independent software application that has been
designed to perform a specific function with emphasis on loose coupling between interacting services and their
components. SOA permits developers to utilize many of the resources from existing services to form the
distributed applications. This study has investigated to highlight the emerging issues of SOA such as service
structures advancement, requirements of evolution for current age applications like mobile-cloud, medical and
mechanism for interoperable operations. The paper also uncovers the practical application domains of SOA. It
has identified research attentions in these domains with detection of issues to carry further research to
overcome constraints in current scenarios.

Cluster based approach for Service Discovery using Pattern RecognitionYogesh Santhan
Abstract— Web services that are appropriate to a user specific request are usually not considered in discovering the exact service since they are present without explicit related semantic descriptions. In our approach, we deal with the issue of service discovery provided non-explicit service description semantics that match a particular service request. We propose a system that involves semantic-based service categorization which is performed at the UDDI with a key for achieving the service categorization at functional level based on an ontology skeleton. Also, clustering is used for literally systemizing the web services based on functionality which is achieved by using analytic algorithm. An efficient matching for the relevant services is achieved by the enhancing the service request semantically and involves expanding the additional functionality (obtained from ontology) that are related for the requested service. The pattern recognition algorithm is used to select appropriate service from the cluster formation of related (grouped) web services.

With the increasing usage of smartphones and other devices, digitization of banking sector is expected to catch up the increasing expectations of the customer. Banks have a significant role in our lives. Every one of us will execute at least a single financial transaction in a day. Hence, it becomes necessary for banks to enrich customer experience. Digitization becomes mandate feature for banks since it is being adopted in all industries in day to day life. Banks love mainframes because only mainframes can provide a single, unified, efficient solution to a host of different problems. Most of the banks uses Mainframe because of it robust, reliable and secured processing power. It also supports the new technologies like mobile, cloud etc., A business case is presented in this paper to explain Micro service and API framework for existing legacy system. Existing architecture is tightly coupled services with less standardization and fair performance. The aim of this paper is to provide solutions to convert the existing architecture to flexible service to support business for time-to-market, increase in performance and operational efficiency and improve customer experience.
Enhancement in Web Service ArchitectureIJERA Editor
Web services provide a standard means of interoperating between different software applications, running on a
variety of platforms and/or frameworks. Web services are increasingly used to integrate and build business
application on the internet. Failure of web services is not acceptable in many situations such as online banking,
so fault tolerance is a key challenge of web services. This paper elaborates the concept of web service

To better cope with the fundamental issues of the traditional client-server based web service architecture, peer to
peer web service architecture have been introduced. The purpose of this paper is to elaborate the architecture,
construction methods and steps of web services and possible weaknesses in scalability and fault tolerance in
traditional client server architecture and a solution for that, peer to peer web service technology has evolved.
METRIC-BASED FRAMEWORK FOR TESTING & EVALUATION OF SERVICE-ORIENTED SYSTEMijseajournal
The increase in the significance of service orientation in system development is accelerating with an increase in demand for qualitative and cost-effective systems. Service-Oriented Architecture (SOA) is one of the established structural designs used for developing and implementing flexible, reusable, rapid and low-cost service-oriented systems. The established testing and evaluation methods don’t work well for systems that are made-up of services (service-oriented system). As a result, several testing and evaluation metrics for service-oriented systems were proposed. However, these metrics were created based on preceding software development approaches that offer insufficient focus to service-oriented systems thereby lacking the efficiency to evaluate these systems. Furthermore, Lack of access to source code also frustrates classical mutation-testing approaches, which require seeding the code with errors. This paper discusses different testing and evaluation metrics available for SOS and proposed a theory-grounded framework for testing and evaluation of service-oriented systems with the aim of decreasing cost and increasing the quality of the SOS. Then, the proposed framework is validated theoretically to check its usability and applicability for testing and evaluation of SOS. The results show that the proposed framework is able to decrease cost and increasing the quality of the SOS.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Abstract- The recent trends in the computer industry are the one
and only thing i.e., web services. Because of the common
availability and open technologies web services are relevant to
all. Service-oriented architecture (SOA) helps organizations to
transform their business processes for high performance by
simplifying the underlying information systems. The most
challenging aspect of building successful software applications is
clearly understanding and specifying the requirements that an
application must satisfy. Use case modeling is an increasingly
popular approach for identifying and defining requirements for
software applications of all types. Use cases describe the
behavior of the system as its users interact with it. This approach
helps to place the software requirements in the framework of a
user doing some useful work with the system. This type of
approach helps to map software requirements to the relevant end-
user business processes, a very powerful concept. This paper
presents how the relationship between use case model and
Service oriented architecture.

I. INTRODUCTION TO SOA
Companies are inneed to integrate existing systems in order to
implement information technology (IT) support for their business
processes which cover all present and prospective systems
requirements needed to run the business end-to-end. A variety of
designs serve this kind of service ranging from rigid point-to-
point electronic data interchange (EDI) interactions to web
auctions. This will be donr by updating older technologies, for
example by Internet-enabling EDI-based systems, companies can
make their IT systems available to internal or external customers;
but the resulting systems have not proven flexible enough to
meet business demands, which require a flexible, standardized
architecture to better support the connection of various
applications and the sharing of data.SOA offers one such
prospective architecture. It unifies business processes by
structuring large applications as an ad hoc collection of smaller
modules called "services".
Service Oriented Architecture (SOA) can be defined as an
evolution of the Component Based Architecture, Interface Based
Design (Object Oriented) and Distributed Systems. A
Component Based Architecture is an architecture where the
functionality of the whole is divided into smaller functions, each
encapsulated in a component. A Distributed System is an
extension of components-based architecture and refers to
components that may exist in different physical locations.This
paper is organized as follows: Section 2 describes about the SOA
entities and its description.It also talks about the guiding
principles for the development, maintenance, and usage of the
SOA. Section 3 describes the necessity for software employees
to adopt SOA and the benefits which they can gain .Section 4
demonstrates about the use cases and its benefits of use cases.
Section 5 describes two different examples to talk about the
relationships between the use cases and SOA. Conclusions are
presented in Section 7.
II. SOA ENTITIES
SOA consists of the following six entities configured together to
support the find, bind, and execute paradigm The “find, bind, and
execute” paradigm as shown in Figure1 allows the consumer of a
service to ask a third-party registry for the service that matches
its criteria. If the registry has such a service, it gives the
consumer a contract and an endpoint address for the service
Figure 1:
Find
Bind and Execute
Register
Service Consumer
The service consumer is an application, service, or some other
type of software module that requires a service. It is the entity
that initiates the locating of the service in the registry, binding to
the service over a transport, and executing the service function.
The service consumer executes the service by sending it a
request formatted according to the contract.
Service Provider
The service provider is the service, that the network-addressable
entity that accepts and executes requests from consumers. It can
be a mainframe system, a component, or some other type of
software system that executes the service request. The service

provider publishes its contract in the registry for access by
service consumers.
Service Registry
A service registry is a network-based directory that contains
available services. It is an entity that accepts and stores contracts
from service providers and provides those contracts to interested
service consumers.
Service Contract
A contract is a specification of the way a consumer of a service
will interact with the provider of the service. It specifies the
format of the request and response from the service. A service
contract may require a set of preconditions and postconditions.
The preconditions and postconditions specify the state that the
service must be in to execute a particular function. The contract
may also specify quality of service (QoS) levels. QoS levels are
specifications for the nonfunctional aspects of the service. For
instance, a quality of service attribute is the amount of time it
takes to execute a service method.
Service Proxy
The service provider supplies a service proxy to the service
consumer. The service consumer executes the request by calling
an API function on the proxy. It then formats the request
message and executes the request on behalf of the consumer. The
service proxy is a convenience entity for the service
consumer.The service proxy can enhance performance by
caching remote references and data.When a proxy caches a
remote reference, subsequent service calls will not require
additional registry calls. By storing service contracts locally, the
consumer reduces the number of network hops required to
execute the service.
Service Lease
The service lease, which the registry grants the service
consumer, specifies the amount of time the contract is valid: only
from the time the consumer requests it from the registry to the
time specified by the lease (Sun Microsystems, Jini Technology
Core Specification, 2001). When the lease runs out, the
consumer must request a new lease from the registry.The lease is
necessary for services that need to maintain state information
about the binding between the consumer and provider. The lease
defines the time for which the state may be maintained
2.1 Principles
The following guiding principles define the ground rules for
development, maintenance, and usage of the SOA:
Reuse, granularity, modularity, composability,
componentization, portability, and interoperability
Standards compliance (both common and industry-
specific)
Services identification and categorization, provisioning
and delivery, and monitoring and tracking
III. ESSENTIAL NEED FOR THE ADOPTION OF
SOA
In general the Information Technology (IT) workers face many
challenges like,
Limited budgets for the modeling system.
Constantly changing technologies.
Evolving technologies for the same business function.
Business requirements that demand applications and
technology silos that need to be integrated with each
other.
Application functionality that must be extended to
reach outside an enterprise firewall
By these factors we can come for the conclusion that the system
require integration. For example, when a core banking system
must be accessed and used by customers through the Internet, a
demand is placed on the system to expose some of its
functionality to the application that drives the Internet access.If
the integration is always in native format (specific to an
application’s programming language or environment), then
integration projects will require a lot of custom integration work.
In addition, the ability to connect multiple systems together
quickly will require highly specialized programming capabilities
and knowledge of the nuances of the individual systems.
Because each enterprise application may be implemented on a
single server that provides the same functionality to many
clients, it makes sense to use common protocols to access the
functionality. IT staff can lower costs dramatically by using
common protocols and standards, and common methodologies
such as SOA.
Figure 2 shows the distinct philosophies of each step that
business has taken to adapt to requirements integration:
1. Vertical silos of integration – keeping all applications and
systems with similar functionality integrated with each other, but
not accounting for applications that may wish to use their core
functionality in the future.
2. Horizontal integration – integration of some but not all similar
functionality across vertical systems; for example using a
common purchasing system for raw materials, shipping needs
and office supplies.
3. The SOA – an environment of ubiquitous service providers
and service consumers interoperating with each other in a secure
and consistent manner.

Many IT workers are placing requirements for this type of
integration on their software vendors. Most of the large and
medium-sized software vendors have either announced or
incorporated SOA methodology in their software.While the basic
patterns of integration remain the same, the specific technology
to implement it does vary, depending largely on the software
vendor.While the technical barriers to integration are easy to
overcome, there are vastly differing business policies and legal
aspects to be enforced at runtime, but no widely accepted
standards exist for them yet. Many software vendors continue to
pursue different methodologies and individual solutions for these
components of the SOA.
IV. USE CASES
Use cases are a powerful technique for capturing and
communicating functional requirements for software
development. A use case describes a set of possible executions of
the system. It describes a complete flow through the system until
the resulting value is achieved for some actor. I can be described
as follows:
• “Sequence of actions”: Atomic activities, decisions, and
requests. Each action is performed fully or not at all.
• “Performed by a system”: The actions performed by the
system are the functional requirements.
• “Observable result of value”: Make sure that the use case
results in an observable value. Why would anybody use the
system if it does not achieve a result of value? If nobody receives
value from the use case, then the use case is probably too small.
It needs to be combined with other use cases to provide a
complete set of steps for achieving some goal for an actor.
• “To an actor”: Decide which particular actor receives the
value and helps avoid use from declarative statements in two
primary ways. They describe functional requirements from the
user perspective rather than the system perspective, and they
provide a coherent goal focused flow of events rather than a set
of discrete declarative statements.
V. RELATIONSHIP BETWEEN SOA AND
USECASE MODEL
In formulating an SOA, we can start with operation. Here the
focus is how end users, systems, or applications use services.
Use cases in Unified Modeling Language (UML) [5] describe the
external behavior of a service as seen or utilized by an actor
(user, system, or application). The boundary of the service in a
use case is clearly delineated. The interaction of the actor with
the service is described without revealing the internal details of
the service. Use case is, therefore, a natural tool for describing
operational activities in an SOA.Based on the operational
concept, the scope of services, and the high-level requirements,
one may identify a set of high-level critical use cases. These are
the use cases that the architecture must support to meet the
minimal requirements. Use cases are not requirements.
Nevertheless, they illustrate what functions architecture provides
and highlight the requirements. Therefore, use cases are the first
step in formulating an SOA (see Figure 3).
Figure 3: Formulating an SOA
In each use case, typically two or more nodes interact with each
other by exchanging information. If a node is a service
consumer, then it is an actor in the use case for that service. If it
is a provider, then it is a component providing that service.
Traditionally, a node in the C4ISR framework represents a role,
an organization, an operational facility, etc. For an SOA, its
scope is expanded to include shared resources and services.
Hence a service node interacts with consumer nodes to provide
services. Use case and node are, therefore, the primary objects in
describing the operational aspects of an SOA, as shown in Figure
3.
Once the operational aspects are identified, the next action is to
find the solution that satisfies the operational requirements. In an
SOA, each service provides a set of well-defined functions useful
to its users, or consumers.
5.1 Operational View
let us consider an enterprise messaging system, in Command,
Control, Communications, Computers, Intelligence,
Surveillance, and Reconnaissance (C4ISR), which encompasses
e-mail, instant messaging (IM), chat, and presence services. The
critical use cases are send and receive emails and instant
messages, participate in a chat session, subscribe to and receive
presence notifications, etc. They are shown in the use case
diagram in Figure 4. In addition, the administrator configures
and administers the services
Figure 4: Use Cases as Part of the Activity Model for the
Enterprise Messaging System

Volume: 01 Issue: 01 June 2012 Page No.1-4
ISSN: 2278-2389

For each use case, you may describe a sequence of events or
activities. These activities may be presented in a hierarchy, as in
the standard activity model operational view .Here, however, the
use cases provide a natural grouping of those related activities.
Additionally, a use case highlights the actors and system/service
boundary, allowing you to delineate roles and nodes easily.
Hence, include use case as part of OV and consider it an
essential product for an SOA.
For an SOA, the use-case diagrams (such as Figure 4) often
identify the nodes. These nodes are roles, organizations, shared
resources, or service nodes. You can further draw the
connections (i.e., the need lines) between the nodes, thereby
forming the operational node connectivity description (OV). An
example is given in Figure 5.
Figure 5: Operational Node Connectivity Description for the
Enterprise Messaging System
Using UML techniques to supplement the traditional C4ISR
framework, I have elucidated an approach for formulating an
SOA. On the operational side, it starts with use cases, which
involve the interaction of two or more operational or service
nodes. Mission functions are provided through applications,
which are implemented by a set of services. The high-level
operational concept graphics still applies to an SOA. This,
operational views together encompasses the concepts of
operation, the use cases from user's viewpoint, the connectivity
between operational nodes, and their information exchanges.
They therefore characterize the essential operational aspects of
an SOA. Furthermore, since operational nodes include shared
resources and services, dynamic and collaborative operational
activities are properly captured
VI. CONCLUSIONS
By this paper I can also conclude that well-written use case
descriptions are a powerful technique for capturing and
communicating functional requirements in many software
development paradigms. In fact, many software development
organizations have adopted use case techniques for their
requirements management efforts on projects that are not object
oriented or using any other UML constructs. SOA is based on
the use of distributed objects and components and is the next
evolutionary step in computing environments. An SOA may also
implement optional concepts that include a service consumer, a
service client, acceptance of the service contract and invoking
the service.There are many business drivers affecting the
development of a standardized SOA reference model. Once this
is achieved, SOA will likely be part of the solution for many
business and world issues. They are by no means a silver bullet
for requirements and UI design, and they certainly have their
pitfalls, but overall they can be a powerful tool for most projects.
The secret is to keep it simple, and to involve the users right the
way along in the identification and design of use cases.
Remember that our aim is to eliminate rework due to
requirements misunderstandings, and so we should be aiming to
reach a point where there are no surprises for the users. Use
cases, in conjunction with SOA techniques help to build an
explicit shared understanding that everyone can take away with
them . users, developers, testers, technical authors, and others.
