Interorganisational Networks

Businesses use many portals and for a variety of reasons. Some portals are used for inter-organisational collaboration between suppliers, buyers, and customers or as electronic marketplaces for users to browse and search for genuine savings in the purchase of goods or services. Portals support interorganisational networks by defining function and content on the basis of the customer process, and provides availability to the user via role-based and personalised interface while e-markets offer to the user a restricted or open view of the products and services on offer. Each profile is determined by the participant or its administrator. Today’s portal technology, paired tightly with tools and services, support user activity in an integrated way. The use of portals is still in its infancy among a number of organisations while early adopters are at the point of experiencing some genuine rewards. Portal technology provides a modular service-oriented architecture for integrating content and services and for managing user profiles and security settings from other systems. Portal technology provides customers the basis for constructing, building, and deploying a variety of Web applications designed to meet the changing business requirements.

Quality Of Service Assurance

The realisation of Service-Oriented Architecture (SOA) to communicate data between systems running on different platforms lack an organised framework to capture the essential elements required for successful interoperability between web applications and their services. In this work, a SOA for Data Interoperability in Web Applications (SOADIWA) was designed. The architecture of SOADIWA was based on five layers, namely Web Application Layer (WAL), Quality of Service Assurance Certifier Layer (QoSACL), Web Service Layer (WSL), Visualization Input Layer (VIL) and Visualization Output Layer (VOL). In WAL, the Service Requester (SR) initiates a request for data from the Service Provider (SP) through the QoSACL to provide appropriate website via WSL for rendering of services which must be accepted, processed and returned for a particular need in VIL. The requested data is filtered in VIL for data exploration and analysis in VOL using context-sensitive visualization techniques. The purpose of QoSACL is to check and verify the claims made by the SP about its quality of service. This enabled the SR to choose the service that satisfied its needs. The implementation comprised of Java Script, Microsoft Visual Studio 2017 and NuGet packages; while the experiment was simulated on LoadUI pro application. Standard metrics such as Optimal Performance (OP) and Phased Effort Distribution (PED) were developed to test SOADIWA. These results conformed to basic web service interoperability. The work led to the integration of a host of techniques towards the creation of a novel tool that is useful in web domain using SOA approach.

Oriented System

Web Service Composition is one of the technologies in Service Oriented Architecture which significantly increases the flexibility and reusability of developing service-oriented system. One of the major problems which occurs in web service composition is the difficulties of maintaining the existing running web service composition solutions due to the changes of business requirements, deployment environment, and other dynamic factors. In this proposed work, an automated system had been built to autonomously execute the web service composition. To achieve this objective, the authors had embedded semantic engine and Prolog in C# program to automatically and dynamically discover, compose and execute web service composition, i.e. a web service composition could be self-configured to automatically recover from execution failure and automatically re-generate composition solution due to business protocol changes.

A maximum-meet user’s individual needs integration model was presented in this paper, which integrated information integration thinking, Web3.0 with open platform. The model embedded Service-Oriented Architecture (SOA) framework realized the information integration. Then combined the OpenID ,OAuth, and role-based access control (RBAC) achieved single sign-on and authorization system; finally, based on Maps API Mashup applications realized the interaction between the LAN Web information and maps. The model has the advantage of friendly interface, strong replicability, and high security.

Role Based

Service-Oriented Architecture (SOA) has introduced a phenomena of system's interaction with maximum users. With the development of high speed Internet services, the use of remote devices and software has rapidly increased. It has opened new gateways for renting out resources. The Cloud Service Chain is a process of ownership transfer of a service at different levels by different service providers. The concept of service chain poses novel challenges related to security, trust and privacy of data. In this chapter, we are introducing a mechanism of access control for Cloud service chains. We have discussed the realization of Role-Based Access Control (RBAC) to services of Federated-Cloud. When services are purchased in bundle, separate SLA is signed for each. We are also going to introduce a dynamic Role-Level Agreement (RLA) for such type of access control to services. The RLA will be an aggregated SLA for different services in a role. This will be helpful for service providers and the customers to sign a single document for a bundle rather than having separate one for every service.

Enterprise Integration enables the sharing of information and business processes among the various applications and data sources within and beyond an organization. Over the years, due to changes in business requirements and availability of sophisticated technology, the architectures for integrating applications and data sources have evolved from simple point-to-point integration technique to more comprehensive architectures leveraging Service Oriented Architecture (SOA) and Event Driven Architecture (EDA). In this chapter, the authors trace this evolution, and examine the architectures in terms of complexity versus business benefit. The architectures are presented in a logical progression starting with the simplest form.
