Mask–Mediator–Wrapper: A Revised Mediator–Wrapper Architecture for Heterogeneous Data Source Integration

Abstract

This paper deals with the mediator–wrapper architecture and observes it in more modern aspects by relating it to architectural quanta. It is an important architectural pattern that enables a more flexible and modular architecture in opposition to monolithic architectures for data source integration systems. This paper identifies certain realistic and concrete scenarios where the mediator–wrapper architecture underperforms. These issues are addressed with the extension of the architecture via the mask component type. The mask component is detailed so it can be reasoned about without prescribing a concrete programming language or paradigm but still providing a working principle. The benefits of the new mask–mediator–wrapper architecture are analytically proven in relevant scenarios. The proof includes a software shift–cost analysis whose results quantitatively show the improvement of the mask–mediator–wrapper architecture over other mediator–wrapper architecture settings. One of the applications of the new architecture is envisioned for modern data sources integration systems backing big data processing.

System Architecture for Geospatial Virtual Data Integration in Web-Based Applications

“…This architecture is based on the mediator-wrapper design pattern. In particular, it is an extension of the Mask-Mediator-Wrapper architecture previously proposed by Dončević (Dončević et al, 2023). The core data integration strategy is realized by the mediator-wrapper pattern, while the presentation is handled by the mask.…”

“…This component constitutes a centralized interface and entry point to the system that provides predefined functions to externalize only certain internal functionalities of the system. This component is adapted from the architecture described by Dončević (Dončević et al, 2023) as an extension of the mediator-wrapper architecture. The rationale behind this component is to provide a unified interface to access the different underlying data sources that the system integrates and the functionalities that the system chooses to externalize (e.g., data processing or analysis, visualization, catalogue).…”

“…Para realizar la adquisición de los datos, en la literatura se encuentran los elementos conocidos como wrappers [57,218], éstos, tienen dos funciones principales [55], las cuáles, se estudian con detalle a continuación.…”
