Automatic localization of services at the time of logical modeling is a difficult task. This is because of the complexity of models and the scattered nature of enterprise architecture information in organizations, systems as well as actors and applications. However, all information about logical services is described in the eLEL and in the aspects of the business architecture of the Praxeme methodology...
System specifications can be modeled using various types of notations and diagrams regarding applications of the particular model. In this paper, we present an overview of the existing solutions, focusing on UML, BPMN and DMN models and the diagrams provided by these notations. We perform a comparison of these approaches and provide examples of representing system requirements in these notations.
Tight coupling of business and the software implementation is the biggest difficulty of designing software system architecture. The business change will inevitably lead to software restructuring, which is the necessary result of business-driven development, and it greatly restrict the development of software productivity. Metadata driven design, as an architecture pattern, can effectively reduce the...
In order to achieve the expected benefits provided by network function virtualization and software defined networks, the key role is placed on management and orchestration functionality with goal to automate services provider business processes. Network function virtualization and software defined networks establish new requirements upon network management systems which demand a change of existing...
Service-Oriented Architecture (SOA) has become one of the most important concepts in designing complex information system. Compared with traditional architectures, SOA can be used to improve fast-respond abilities and to satisfy frequent changing of business requirements. A dispatch method of complex information system that is based on SOA is proposed in this paper. The function framework and procedure...
Our experience with email-based marketing campaigns (or short: “Microservices”) showed that they are an intersecting set of a) projects and processes and b) technology and creativity. Their properties of fixed due date, fixed scope and at the same time fixed duration render classical management methodologies unfeasible. The same applies to the supporting enterprise infrastructure architecture, where...
Analysis and planning of Enterprise Architectures (EA) is a complex task for stakeholders. The change of one architecture element has impact on multiple other elements because of manifold relationships and interactions between them. The interactive cockpit approach presented in this paper supports stakeholders planning and analyzing EAs and to tackle the intrinsic complexity. This approach supplies...
The integration between enterprise architectures and Business Process Management Systems (BPMS) is currently based on low-level programming interfaces that expose accidental complexities typical of process implementations. This paper describes an approach for integrating software architectures and BPMSs, based on mapping frameworks. Our inspiration are the Object-Relational Mapping (ORM) frameworks...
This paper presents ES-SQL, an embedded tool for visually constructing queries over spreadsheets. This tool provides an expressive query environment which has knowledge on the business logic of spreadsheets, and by this knowledge it assists the user in defining the intended queries.
One of the problems we face today for software development is how we can comply with the speed of change in the business environment. To address the issue, we present a new paradigm called Progressive Development Model that gradually releases the software components according to the current business needs. In this paper, we also present a design pattern of software architecture optimized for Progress...
with the spread of a large number of web application, more and more software requirements are proposed. Especially in management information system, it is necessary to maintain the scalability of the database and the flexibility of the software architecture. To meet the development of the software, a lot of novel technologies are presented. The framework based on Struts, Spring and Hibernate is one...
In enterprises using service-oriented architecture (SOA) architectural information is used for various activities including analysis, design, governance, and quality assurance. Architectural information is created, stored and maintained in various locations like enterprise architecture management tools, design tools, text documents, and service registries/repositories. Capturing and maintaining this...
Development of service-oriented architecture has become more and more maturated. It provides a good solution for integrated design of complex system in effected. provides a better framework for simulation of complex system. This paper introduces concept, principle, essential characteristic and technique advantages of SOA, design integration of independent functions on heterogeneous platforms and reuse...
This paper presents an approach to implement distributed simulation software to test, validate and improve information exchange between enterprises. The approach assumes some of the recently released HLA Evolved standard web service requirements. The implementation is based on improving the open source poRTIco HLA RTI tool. The paper mainly focuses on the presentation of the HLA web-enabled federate...
SaaS (software as a service) is becoming an increasingly prevalent software delivery model. Customization is a prominent characteristic of SaaS applications, but traditional SaaS applications lack of the customizability, or only achieve selective configuration on functional modules. Based on the MOF (Meta Object Facility) theory, this paper designs component-oriented meta-model which provides automatic...
The Service Oriented Analysis and Design is a new paradigm into the Software development model. This is a meet-in the - middle architecture which enables the complete process of application building simple and flexible. This paper is comparing the SOAD model with OOAD model and highlights the advantages of SOAD model in the case of Educational Information System.
With the new trend of shifting from traditional architectures towards Service-Oriented Architectures (SOAs) today, the need to model integration becomes increasingly apparent. This study analyzes two main approaches for SOA integration modeling: using Unified Modeling Language (UML) and Service-oriented architecture Modeling Language(SoaML), having as a fundament a literature study, an evaluation...
In the Distributed System design, a .NET based N-layer Architecture pattern is proposed. It separates the Business Logic Layer, Data Access Layer and Presentation Layer; effectively reduces the redundancy in coding, thus promotes an improved expandability for the entire system. A specific implementation method is presented regarding the Data Service Layer and Business Service Layer, thereby better...
Many organizations perceive the importance of linking business architecture to application architecture. It is difficult to manage the changes needed by the business and maximize the benefits from the information technology (IT) investments without this linkage. Linking the two domains require that we define the two architectures using a "common language". The architecture domain has tools...
This paper propsed design and implementation solution of rights management system based on RBAC model, and introduced the multi-layer structure design using J2EE architecture, described role-based access control (RBAC) model design, and discussed the core object-oriented design models of rights management system, and permission access, access control and permissions storage mechanism and other key...
