This paper proposes multi-query unification, a technique for generating unified components from a DFD aimed at reducing the total cost of data transmission between components that are deployed to a computing fabric that includes processing nodes and interconnection services. The method focuses on generating components of the two primary data processing(More)
We propose a runtime composition method for creating various applications that comprise elaborate big data processing. Cloud platforms are required to be more capable at applying elaborate big data processing to various services for real businesses. Therefore, the platforms should be extensible to compound emerging runtimes. However, there are two major(More)
Business matching and collaboration support systems are useful, in particular for small-and-medium companies. Most of them developed so far are based on the server-client architecture and provide their services on Web servers. They require special administrative facilities, ask users to upload their data for matching between business needs and seeds, and(More)
This paper describes practices for multi-level modeling by only using existing modeling frameworks that comply Meta-Object Facility (MOF). We design modeling patterns for achieving the multi-level modeling methodologies on Eclipse Modeling Framework, and implement the dataflow model by applying the patterns. Moreover, we attempt to compare the patterns(More)

Web API is a modern approach for exposing service data to use for applications, however, decision on Uniform Resource Identifiers (URIs) from an existing web application is still a manual and very time consuming task. Depending on the existing web application, thousands of lines of code has to be read and discussed to decide on what data can be exposed as(More)
We need to have comprehensive knowledge about when, where and how we should use multi-level modeling methodologies and frameworks. There are previous work that introduce patterns and confirm the applicability of the methodologies. However, it is still difficult to select frameworks for various kinds of applications. In this paper, we focus on graphical(More)
This paper discusses two ways to establish the connection between two levels in a multi-level model. The first approach uses normal associations and generalizations under the assumption that the multi levels are represented in one UML and OCL model. The second approach views a middle level model both as a type model and as an instance model and introduces(More)
