With the growing popularity of mobile computing and the empowerment of mobile devices by high end-users and decision-makers, the development of architectures based on web services for the deployment of mobile Spatial OLAP (SOLAP) applications is being perceived as a powerful solution. This paper deals with geospatial (web) Services-Oriented Architectures (SOA) for mobile processing of geo-decisional information. The paper first reviews the underlying concepts of typical SOLAP applications as well as the general concepts of mobile computing. The existing SOLAP functionalities are presented and their viability/usefulness in a mobile environment are discussed. Different web services based on an extended geospatial SOA are then proposed in order to tackle the several issues related to mobile SOLAP. Finally, several research challenges and outlooks are discussed.

    • "Dans une architecture élargie pour applications SOLAP mobiles, d'autres services Web peuvent compléter les fonctionnalités du service de constitution de mini-cubes. Plusieurs de ces services sont décrits dans (Badard et al., 2008) ; en voici un aperçu : – Service d'authentification et de gestion des droits d'utilisation : ce service permet d'authentifier les utilisateurs et de donner accès aux cubes correspondant à leurs droits d'utilisation, afin de sécuriser l'accès aux données confidentielles. – Service d'entreposage de mini-cubes : sert à indexer et à stocker les mini-cubes générés par le service de constitution.

    ABSTRACT: Spatial OLAP (SOLAP) réalisées jusqu'à présent sont conçues pour les environnements informatiques de bureau. Dans le but de supporter l'aide à la décision géo-spatiale en situation de mobilité, certaines adaptations à SOLAP sont nécessaires. Cet article décrit une solution, basée sur les architectures orientées services et les technologies des services Web, pour adapter les cubes de données SOLAP afin de répondre aux exigences et contraintes reliées aux environnements informatiques mobiles et aux réseaux sans-fil. ABSTRACT. Existing Spatial OLAP (SOLAP) applications are targeted towards desktop computer environments. In order to enable geospatial decision support in mobility contexts, SOLAP re-quires some modifications. This paper describes a solution, based on service-oriented architec-tures and Web services technologies, designed to adapt SOLAP data cubes to the requirements and constraints encountered in mobile computing environments and wireless networks. MOTS-CLÉS : Spatial OLAP, SOLAP, entrepôt de données géospatiales décisionnelles, informa-tique mobile sans-fil, service Web, architecture orientée service.

    ABSTRACT: XML and Web Services technologies have revo- lutionized the way data are exchanged on the Internet. Meanwhile, Spatial OLAP (SOLAP) tools have emerged to bridge the gap between the Business Intelligence and Geo- graphic Information Systems domains. While Web Services specifications such as XML for Analysis enable the use of OLAP tools in Service Oriented Architecture (SOA) envi- ronments, no solution addresses the exchange of complete SOLAP data cubes (comprising both spatial and descriptive data and metadata) in an interoperable fashion. This paper proposes a new XML grammar for the ex- change of SOLAP data cubes, containing both spatial and de- scriptive data and metadata. It enables the delivery of the cube schema, dimension members (including the geometry of spatial members) and fact data. This XML format can be used in the development of Web Services to be deployed in various situations, not limited to traditional client-server plat- forms but also ubiquitous mobile computing environments.
