Spatiotemporal information and application have received considerable attention. Spatiotemporal information is often imprecise or uncertain; therefore, the establishment of a reasonable and effective fuzzy spatiotemporal data model is vital. The traditional tool-based modeling method cannot meet the needs of fuzzy spatiotemporal data modeling. XML has become the standard of Web data representation...
Although the database schemas are an integral part of information systems, the use of software product lines has been mainly studied for the production of executable code. The impact on data management and in particular the database schemas are poorly documented and little studied in the literature. The paper is an attempt to explore some of the issues of the modeling and implementation of the variability...
Advances in database technologies are moving the attention of data managers from well known structured relational databases (SQL-Like DBs) towards NoSQL approaches, especially to address big data issues. However, changing technologies in consolidated data management system is hard and requires great investments. Deploying hybrid SQL-NoSQL approaches could be a good solution to speed up the transition...
There has long been a challenge of making engineering tools from multiple disciplines interoperate. This problem extends to system modeling practices. This challenge has been confronted with a wide variety of techniques. These techniques include attempting to interface tools together into combined suites, attempting to find underlying commonalities in mathematics, supporting connections through semantic...
Distribution system operators will gather an increasing amount of electricity data from the lower level of the grid to be able to cope with several challenges, such as an increase of distributed, heterogeneous energy production, local storage, and electric vehicles. Most DSOs are not yet prepared for collecting, storing and processing these large amounts of data. This paper introduces a method for...
Many object-relational mapping (ORM) frameworks have been proposed for providing data persistence using relational databases. In general, an ORM framework needs to compromise two contradictory requirements, that is, (1) the support of persistent classes that are directly mapped to relational tables and (2) the support of complicated compositions of the base classes which are required by the complicated...
One of the main objectives of the software engineers is to provide software related solutions for social problems and to increase the availability of social welfare. In that sense, the quality of the software is directly related to address the users' needs and their level of satisfaction. To reflect user requirements to the software processes, the correct design of the database model provides a critical...
Due to the wide range of tasks of modern simulation systems in military context, most simulations take place in an isolated application with preprocessed simulation data. A first step towards running cross domain simulations is to bring together the simulation data schemas. The use of international standards on data modeling, data storage and visualization is prerequisite to achieve such a system...
Data warehouses are a major component of data-driven decision support systems. They rely on multidimensional models. The latter provide decision makers with a business-oriented view to data, thereby easing data navigation and analysis via On-Line Analytical Processing tools. They also determine how the data are stored in the data warehouse for subsequent use, not only by OLAP tools, but also by other...
This paper has proposed a Graph — semantic based conceptual data model for XML based Data Warehouse (DW) system called GXDW model, to conceptualize the different facets of multidimensional databases which may contain semi-structured data. The model is an extension of object oriented paradigm and defines a set of graph based formal constructs, variety of relationship types with participation constraints...
Unified Modeling Language is a kind of language which can be applied to describing, visualizing, framing software system and to business modeling. It contains analysis, design and realization of object-oriented technology, providing abundant, precise expression with strong extension ability for object oriented system development, software automation tools and environment. The paper introduces the...
The U.S. Department of Defense (DoD) Joint Staff, Force Structure Directorate (J-8), along with the Office of Under Secretary of Defense for Personnel and Readiness (OUSD(P&R)) put forth the Global Force Management Data Initiative (GFM DI) with the goal of developing a reliable and maintainable enterprise data source capturing Organizational and Force Structure Construct (OFSC) information. The...
This paper describes the basis and functionality of a semantic database system that supports building, analyzing, and comparing any models that can be described in English. The examples are from the domain of system development but the tool can be used for models in any domain.
In order to meet the complicated data connection between multi businesses, to meet the original business change on structure and application, to meet the multi-user management, we designed the unified database model of user-defined businesses based on those concepts of Business, ManageClass, Indice, Indice_Group, User, Instance and so on. This paper introduces the object-oriented database modeling...
In this paper, we propose an approach to integrate the domain ontology life cycle in database scheme process design. To this end, we lay down that: (i) the ANSI/X3/SPARC architecture is used as modeling framework, (ii) ontology and data semantics are both captured into external schema and propagated to lower level schema, and (iii) ontology-based knowledge is stored in database. As a result, our approach,...
In view of university multi-school district coexisting and many libraries distributed in the different school district, system hardware cost is high, the load of system maintenance is big, the extendibility of system is bad, so we develop library management system's modeling research based on the Web. In the modeling process, we use the UML standard modeling technology to construct system's structure...
Data management has become a critical challenge faced by a wide array of scientific disciplines in which the provision of sound data management is pivotal to the achievements and impact of research projects. Massive and rapidly expanding amounts of data combined with data models that evolve over time contribute to making data management an increasingly challenging task that warrants a rethinking of...
There have been several authors asserting that conceptual query languages (CQLs) perform better for querying purposes than logical query languages such as SQL. This paper proposes a query mapping algorithm for the FConQuer system. FConQuer is a framework based on object-role modeling (ORM) schemas, which allow the end-user to formulate conceptual queries through the FConQuer language. Our mapping...
Increasing market competitiveness has led entrepreneurs to require more and more information from Information Technology areas to allow for efficient decisionmaking. Two alternatives to solving this problem are allied in this work: use of Model Driven Architecture (MDA) and Data Warehousing (DW). This research developed and tested a MDA cartridge. It creates scripts for automatic generation and loads...
In tandem with the growing important roles of software in modern society is the increasing number of threats to software. Building software systems that are resistant to these threats is one of the greatest challenges in information technology. Threat identification methods for secure software development can be found in the literature. However, none of these methods has involved automatic threat...
