Conceptual Graphs (CGs) are a knowledge representation language based on the existential graphs of Ch. S. Peirce and the semantic networks of Artificial Intelligence. CGs are also a modeling and design language, which is human readable and computer tractable. This makes CGs suitable for a large variety of applications. The novelty of this paper, is a new approach to XML data modeling based on Conceptual...
Models are the cornerstone of Model-Driven Engineering (MDE). Their size is constantly growing, becoming one of the main problems when it comes to manipulating them, via model-to-model transformations, model-to-text transformations or simply parsing them. In this paper we propose a way of distributing Ecore models representing them as JSON and URLs as identifiers, since HTTP is one of the most successful...
In recent years, millions of people are connected on social networks. Social networks have become an excellent platform for sharing information and communication that reflects real world relationships. This global use of social networks has made them to be an excellent candidate for using cloud. As a result, numerous access control methods have been proposed to maximize available resources. In addition,...
In object-oriented software modeling using the Unified Modeling Language, different aspects of a system are represented by various types of diagrams. UML diagrams represent two different views of a system model. They are static and dynamic views. In this paper we study the dynamic view of Class Diagrams and static view of Sequence Diagrams for checking consistency among them. We assume that the system...
Now-a-days with the enormous synthesize and increasing use in the arena of cloud computing, smart devices, and business intelligence, Big Data also has become a growing area of research. Yet in literature existing approaches regarding logical level designing of Big Data is very rare. Most are about representation of both semi-structured and structured data and from the perspective of schema-base....
In a Cloud environment, an independent service or model referred to as object storage is used for the management of persistent data. This model provides a virtualized pool of storage resources and can be accessed via Application Programming Interface (API) and/or simply a browser. Object storage is used to store the persistent data from various users through put/get methods and it also store the virtual...
Technical evolution has been improved day-by-day in web services. Service provider has provided several monumental changes to fulfill the requirement of service requester. Generally these services are provided through functional and non-functional Quality of Service (QoS). Most of these models lack unique factors like selection, ranking and other QoS parameters. The proposed system describes the Web...
Methods used to gain executable architecture are all based on transforming view models to executable models, which can not take the advantage of “data-centric” approach adopted by DoDAF2.0. A novel executable architecting approach transforming DoDAF Meta-model (DM2) to executable model directly is proposed, which can overcame the limitation of traditional approaches that information consistency and...
In this paper, we provide a comprehensive survey of the methods available to (semi-)automatically generate an Ontology model from a data model. Although there are several different instantiations of database management systems in use today, the transformation methods to date have generally focused on relational data models as the prime source of the information; we therefore concentrated on this when...
In order to solve the sharing problem of heterogeneous data, provide a standard, unified, feature-rich interface, the traditional SDO data integration has been improved and the P2P added server support . It has improved the level of mutltiplexing module reduced the complexity of communication. users can access it from the peer,but cdn,or other servers.
Trust-based access is an established technique in many fields, such as networks and distributed systems, but has not previously been used for XML (Extensible Markup Language) databases. In trust-based access control, user privileges are calculated dynamically depending on the user's trust value. Applying the technique to XML databases should have many advantages over current techniques, such as role-based...
In modern enterprises, each enterprise's data content and data structures are very different. With the development of enterprises, their business models and data models are constantly changing. The dynamic data modeling tool which was discussed in this paper is mainly to solve the dynamic of business needs. The tool includes data modeling tool and page layout tool. Data modeling tools which serialized...
This paper presents a system for automatic annotation of handwritten historical documents based on Markov models. The proposed system first extracts XML schema which describes a specific domain and than a Mapping algorithm is used for the generation of the new XML schemes. Mapping algorithm has as inputs two schemes reference schema and a specific schema. XML schemes are generated using Markov models,...
This paper made an in-depth research on information resources and personalized service and research status of system implementation techniques, combined with the practical work of graduate design, the use of Ajax, database, network communication and ASP.NET and other technologies on information resources and personalized service system's overall architecture was design. The system uses a hierarchical...
Entity Data Model (EDM) is a new conceptual model developed by Microsoft; it is a Platform-Independent and executable conceptual model. At present, EDM is mainly used for information integration, so Microsoft has developed the tools for transforming Platform Specific Models, such as Relational Data Model (RDM), to EDM. On other hand, EDM as a conceptual model can also be used for designing database,...
Provenance, a record of the derivation history of scientific results, is critical for scientific workflows to support reproducibility, result interpretation, and problem diagnosis. Both prospective provenance, which captures an abstract workflow specification as a recipe for future data derivation, and retrospective provenance, which captures past workflow execution and data derivation information,...
Because such lots of information as data, personnel, model etc., which are involved during the course of virtual designing and co-simulation, need be managed integratedly, according to the overall system structure of webifying virtual designing and co-simulation, the multidisciplinary integrated management technology is studied, and the system structure of integrated management platform is put forwards;...
Applications like stock markets, embedded systems and telecommunications are becoming more demanding real-time database management systems. Research in the area of real-time databases leads to the development of sophisticated control algorithms and for testing these in different configurations we need a simulator framework that allows us to see how they behave for different transaction workloads....
Knowledge processing of instructional intelligent expert system is discussed in this paper. The study is based on the theories of Knowledge Engineering. The design method and model is also presented, which is based on the frame, production rule and XML.
It originated in the use of ROSE tools, based on MDA development system method, when the model conversion was found that the model can not be automatically converted, for example, the length of type need be completed manually in the Relational Database. The paper advanced through XMI standard, XML had self-descriptive and platform-independent, in the XMI/XML platform technology support, platform independent...
