- Readly - Books Rating Low-Code PlatformPublication . Nascimento, Bruno; Santos, Rui; Abrantes, Steven Lopes; Quental, CarlosThis article addresses the development of a digital platform within the OutSystems ecosystem, embracing the principles of Low-Code and No-Code application development. The platform facilitates users in sharing their ideas, opinions, and reviews with a community of fellow book enthusiasts. Users can discover new titles, engage in debates, and foster connections by offering a space for meaningful conversations and suggestions. The platform empowers users to contribute to a shared knowledge base by providing book ratings and reviews, thereby assisting others in their book selection process. The emphasis lies in delivering a seamless, user-friendly experience through a modern and clean interface, further enhanced by personalized book recommendations tailored to individual user preferences. In the context of the rapidly evolving landscape of application development, Low-Code and No-Code approaches have gained significant traction due to their efficiency and accessibility. This article aims to highlight the integration of these approaches within the development of the digital platform. Utilizing the capabilities of the OutSystems ecosystem, which inherently embraces these concepts, the platform’s creation becomes a testament to the versatility and benefits of such methodologies. In conclusion, this digital platform not only caters to the needs of book lovers by equipping them with a range of tools, but it also stands as a prime example of the successful implementation of LowCode and No-Code development strategies. These tools encompass organizing reading lists, active community participation, and receiving customized literary suggestions. The application achieves a fluid and intuitive user experience, further facilitated by incorporating low-code principles. It enables users to manage their reading materials effectively, set goals, track progress, rate and review books, and engage with fellow bibliophiles. This comprehensive solution empowers book aficionados, enriching their digital reading journeys while showcasing the prowess of Low-Code and No-Code application development in creating impactful solutions.
- Scalability and Performance Evaluation of NewSQL and Relational Databases: A Comparative Benchmark StudyPublication . Nascimento, Bruno; Santos, Rui; Abbasi, Maryam; Martins, Pedro; Silva, José; ANTUNES VAZ, PAULO JOAQUIMThe purpose of this article is to test and compare the scalability and performance of NewSQL databases (CockroachDB and SingleStoreDB) versus standard relational databases (MySQL and PostgreSQL). The dataset chosen for this benchmark was an TPC-H generated database, making it a suitable dataset for testing database scalability and efficiency in handling complex queries and big amounts of data. To execute the benchmarking, we will construct assessment criteria based on 3 main categories: Process, Performance and Strategy. In this way, it will be possible to evaluate the behavior of each solution, in different contexts and how they use the respective functionalities to obtain the best result. A Benchmarking tool is essential for obtaining sustainable, reliable, and communityaccepted indicators, as it uses standard metrics to assess and classify behavior and performance. Based on these paradigms and the mechanism used for data generation, the benchmark tool chosen for this paper is the TPC-H Benchmark, which explores the data organization and complexity. The results of this benchmarking will give significant insights into the strengths and drawbacks of NewSQL and RDBMS databases, as well as whether the database is better suited for certain use cases. Furthermore, using a dataset like TPC-H will deliver more accurate and useful results, allowing developers and database administrators to make more educated database selection selections. Another point to check is the behavior of technologies in the face of a large volume of data, which is something natural and increasingly common nowadays.
