This presentation is from 2010. Although SOA was an 8 year old technology at the time, many enterprise IT organizations were still struggling with the basic question of “what is a (web) service?” While the question sounds basic, initially services were focused on ‘whatever application functions could be exposed’ – a programmer oriented paradigm. How to tie services to business and enterprise value, or what to focus upon to get practical value out of integration, was a major concern.

Use of SOA and Web Services Technologies for EA Migration - Lessons Learned o...

Nathaniel Palmer

SOA and Web Services technologies can provide powerful tools and capabilities to effect migration towards an Enterprise Architecture (EA), but what are the challenges to such an exercise, and how can they be overcome? Based on a case study at the Department of Housing and Urban Development (HUD), the first effort in HUD to analyze and design the replacement of several legacy systems with an integrated and services-based system, this presentation will provide a technical overview of SOA and Web Services, and lessons learned from the project. These lessons will cover methodologies and modeling artifacts that were developed for the effort, the use of BPM based on the Business Process Execution Language (BPEL) and system adapters to provide an abstraction layer for system integration, an example of how Web Services can directly support EA migration, and final considerations to pass onto similar projects.

Core vocabularies and Metadata Sets for Governments

Yannis Charalabidis

Public Sector Information management frameworks, usually in the form of ontologies and taxonomies containing controlled vocabularies and relevant metadata sets, appear as a key enabler that assists the classification and sharing of resources related to the provision of open data and efficient digital services towards citizen and enterprises. As different authorities typically use different terms to describe their resources and publish them in various data and service registries that may enhance the access to and delivery of governmental knowledge, but also need to communicate seamlessly at a national and pan-European level, the need for unifying and inclusive digital public service metadata standards emerges. This paper presents the creation of an ontology-based extended metadata set that embraces public sectors services, documents, XML Schemas, codelists, public bodies and information systems. Furthermore, the paper presents experiences of application within the Greek Public Sector, as part of the National Interoperability Framework specification. Such a metadata framework is an attempt to formalize the automated exchange of information between various portals and registries and further assist the service transformation and simplification efforts, while it can be further taken into consideration when applying Web 2.0 techniques in governance.

XML Schema Design and Management for e-Government Data Interoperability

Thomas Lee

One-stop public services and single window systems are primary goals of many e-government initiatives. How to facilitate the technical and data interoperability among the systems in different government agencies is a key of meeting these goals. While many software standards, such as Web Services and ebXML, have been formulated to address the interoperability between different technical platforms, the data interoperability problem remains to be a big challenge. The data interoperability concerns how different parties agree on what information to exchange, and the definition and representation of such information. To address this problem, the Hong Kong government has released the XML Schema Design and Management Guide as well as the Registry of Data Standards under its e-Government Interoperability Framework initiative. This paper introduces how the data modelling methodology provided by the Guide can be used to develop data interfaces and standards for e-government systems. We also discuss how the Macao government has formulated their data interoperability policy and has applied the Guide in their situation.

METRIC-BASED FRAMEWORK FOR TESTING & EVALUATION OF SERVICE-ORIENTED SYSTEM

ijseajournal

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.

IJECEIAES

The lack of identify services mechanism which is related to the development of information systems could be impact in wasting time, over budget and can not adapt to the changing environment. This phenomenon is happened by the belief that lack of capturing user requirement. This is due to consider the business environment is always running normally. In fact, the development of the system needs a way to anticipate the business environment that unpredictable changes.Therefore, the phenomenon on the need for modeling services can able to respond to the changing needs of users still have a chancein this study. It explores modeling services to synergize SOA and BPM.Several previous studies generally use a business driven approach, technical partially driven to develop the service modeling. This leads to the question of how a service should be modeled so that it can be applied in different contexts and business processes also. It is support user needs in diversity and heterogeneous system environments. This Conditions occurs in corporate university. The case studies in this research is a Learning Management System (LMS) in Academic Enterprise System (EAS). The research stages are: (1) Analysis of Synergy in SOA and BPM, (2) Analysis of User Experience in LMS Academic Enterprise System (L-EAS), (3) Analysis of Modeling Framework, (4) Proposed Framework that aligning SOA and BPM. The result of this study is proposed system framework based on services to increase the flexibility of information systems at LMS Academic Enterprise System (L-EAS).

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Elevating Tactical DDD Patterns Through Object Calisthenics

Dorra BARTAGUIZ

After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
