Smart and Sustainable City Experience on Smart Campus: A Case Study from Hassan Ist University

Asian Journal of Research in Computer Science, Mar 1, 2024

In this sense, the trend at the global level is to use smart city standards by investing in the digital transformation of various public services in cities. In recent years, many efforts have been made in many Moroccan cities to improve their attractiveness by being part of the process of upgrading and enhancing their territories through the implementation of major infrastructure projects and the digitalization of urban administrations. This study was conducted to examine the feasibility of a smart campus as a discounted smart city, and it relies on the dissemination of a quantitative survey, via a questionnaire (live and online), supplemented by a qualitative survey based on focus group methodology. We have gained a broader perspective that allowed us to understand the reality of things on campus. The study also showed that there are many efforts that the university must take in conjunction with developing its plan to advance Hassan I University to the ranks of smart universities. This article is part of a study proposing a strategy for developing the campus of Hassan I University of Settat to be a smart one.

Data Integration System for RDF Data Sources

The Semantic Web (SW) is full of data sources serialized in various formats and extensions (e.g. RDF, OWL, XML, etc) and they are created from scratch or by the transformation of other existing sources (e.g. relational database), and so it became one of the most major data sources that can be used to fulfill the analysis’ needs in a decisionmaking system. The OWL 2 ontology language as a W3C recommendation is built on the RDF data model and used to provide the means for defining and creating structured web ontologies. The purpose of this paper is to propose a new architectural system to perform a data integration process to populate an existing data warehouse using linked data (i.e. data from semantic web) as sources.

Semantic Enrichment of XML Schema to Transform Association Relationships in ODL Schema

It is possible to realize the concepts of ODL in a model of XML schema, we propose to introduce an enrichment concretizing these concepts in the XML Schema models. We chose oriented object database as a target database because there are many common characteristics between XML and object-oriented model, thus the mapping from XML data into objectoriented databases is more interesting. Also the object-oriented data bases have become very widespread and acceptable and they offer an evolutionary approach, so we agree that it is time to develop a translation between XML and OO databases. The purpose of this article is to automate transformation process of an XML schema to an ODL database. Our work focuses on preserving semantics transformation of association relationships and we describe set of rules to create ODL classes from an enriched XML schema. The experimental study shows that the approach is feasible, and results are the same, the source database is transformed into target one without loss of data.

The result of the transformation is presented in a variety of diagrams. This work maps XML Schema into a generic object oriented database schema and store related XML document into the database. This process preserves the structure of XML document. The purpose of this article is to automate transformation process of an XML schema to an ODL database. Our work focuses on preserving semantic transformation of Non-monotonic inheritance relationships with constraints and we describe set of rules to create ODL classes from a XML schema. The experimental study shows that the approach is feasible, and results are the same, the source database is transformed into target one without loss of data.

Conversion of an XML Schema to Object Relational Databases Using a Canonical Data Model

This last is the most recommended, however it lacks the object-oriented aspect. And also all the XML data flowing in the web are badly managed. So our paper came to resolve this problem by converting automatically XML Schemas to an Object-Relational Databases (ORDBs), which will allow us to manage XML data easily through SQL query. To do that we’re going to use the CDM (canonical data modeling) by giving an algorithm that’s going to conserve all type of relationships such as association, composition, aggregation and inheritance..., our prototype algorithm will be able to extract the schema metadata from the XML file and convert them into information represented as classes and relationships that are mentioned before. Simplicity and efficiency, those are the strength of our approach to come up with a system that generates a set of User-Defined-Types (UDTs...

We treat the UML profile for XML schema which represents the XML Schema data structures in the form of a UML profile, a UML profile and transformation rules are defined.
