Web-based Editor for Entity-Relationship Modeling with SQL Transformation Algorithm
<p>With the daily growth of data in all kinds of sectors, such as <span>Information Technolo</span><span>gies (IT)</span>, healthcare, education, commerce or telecommunication, it becomes important to use a high-performance system to manage all this data in the best possible way. Indeed, in the absence of good data management, it can be difficult for these sectors to prevent data loss, ensure safe maintenance or guarantee data security. For this reason, an effective data management system is the Entity-Relationship model. Indeed, thanks to this model, all kinds of sectors have the possibility of designing and organizing their data in relational databases, thus improving data security and better internal communication. Furthermore, it is interesting to modernize the classic approach of the Entity-Relationship model and its visual representations of data in the present day. The technologies of Augmented and Virtual Reality respond precisely to this challenge of innovation in the Entity-Relationship model. Therefore, the first objective of this thesis is to implement the Entity-Relationship model in a Meta-Modeling Platform for Augmented and Virtual Reality. The second objective is to implement an algorithm that transforms an Entity-Relationship model into SQL statements to create database tables. The Entity-Relationship model is used to design the logic of a database, and the implementation of the algorithm is used to create the database.</p>
Multivocal Literature Mapping on DSLs and Tools for Entity-Relationship Modeling
<p><strong>[ERES 2021 - Fórum de Pós-Graduação]</strong></p> <p><strong>Abstract:</strong> The variety of database system technologies that became available in recent years makes difficult the selection of tools for modeling entity-relationship (ER). In this sense, we contribute with an overview of the recent innovations through a systematic literature mapping complemented by research in the gray literature. This paper scopes ten (10) primary studies focused on Domain-Specific Languages (DSL) and identifies fifty-five (55) tools already applied in industry and academia for ER modeling at the conceptual, logical, and physical level. Hence, as a significant increment to existing mapping studies, this presents the state of the art and practice for ER modeling, including its characterization and research gaps.</p>
