In this paper, we propose a spatial ETL toolkit model, regardless of collectible data format, to replace traditional ETL (Extract, Transform, Load) to process public or individual system server with fast data creation. Recently various web servers, and the need of analyzing structured/unstructured Big-Data log information generated by independent high-speed servers are increasing. In addition, the...
In this system oriented paper we describe the architectural framework and information flow model of a stochastic discrete event simulator for evaluating military operational plans. The simulator is tailored for Effect-based Planning where the outcome of a plan is compared with a desired end state. The simulator evaluates several alternative plans and identifies those that are closest to the desired...
With the rapid growth of data in various domains, models for data processing become more and more complicated and require higher and higher computing power of local machines. In our opinion, it is a good solution to put models into the "cloud". Integrating and categorizing these models in different domains is convenient for users. They don't have to establish similar systems for different...
XML (extensible markup language) has become the standard of data representation and data exchange in the Internet. A highly efficient management on XML documents has become an urgent problem. In this paper, we introduce the development of a native XML database management system, called dasiaXSQSpsila (XML storage and query system), which provides the ability of the storage and query for XML documents...
The most fundamental ingredients of computer simulations are the analytical or experimental models and their visual representations (views). This paper presents AVRA, a framework that receives the simulation models and the description of the view as XML files and dynamically generates a VR (Virtual Reality) application that corresponds to those specifications. The result consists of a 3D scene with...
This paper describes a benchmarking workload model for business process execution language (BPEL) engines for Web services. The proposed model is based on simulation of real world traffic conditions by defining a set of requirements which best characterize the end-users. The performance characteristics are evaluated on top of collected measurements such as success/fail rate, response times or round-trip...
