This thesis deals with design and implementation of a web application to support interactive tuition in programming within the IZP - Course of Programming Essentials. It enables students submit their own solutions to a specific task and allows them to review some tasks completed by other students. Web pages are created with respect to maximum accessibility of their content and functionality. Their layout and controls are designed in such manner to make them accessible both by alternative browsers as well as by people with specific needs. The application design is created using the UML modelling language. The very application is implemented using the PHP script language together with theXHTML, cascade style sheets (CCS) and the MySQL database system. This thesis also focuses on implementation of the system on FIT websites and its utilisation by students.

A latency comparison in a sharded database environment : A study between Vitess-MySQL and CockroachDBLundh, Filip, Mohlin, Mikael January 2022 (has links)
The world is becoming more and more digitized which in turn puts pressure on existing applications and systems to be able to handle large quantities of data. And in some cases, that data also needs to be operated in secure and isolated environments. To address these needs, a new category of databases has emerged, by the name of NewSQL. The downside of this new category is that it still remains unexplored in some areas, such as how each database under that category performs towards each other, or even towards databases belonging to other categories. One major aspect, in terms of performance is latency, since it affects the overall user-experience. In order to clear up some of the unexplored areas within NewSQL, two databases were studied in the context of their latency performance: CockroachDB and Vitess. The study was divided into two main parts. The first one, was a quantitative study, which was about gathering data on how each database performed in terms of latency when serving the create, read, update, and delete-operations. No clear differences in latency were found for the create- and read-operations. While the results for update- and delete-operations showed significant differences where Vitess had lower latency than CockroachDB. The second part of this study was a qualitative study, dedicated to analyze and inspect each database architecture and source code. The intention was to identify potential factors that may affect latency performance. The outcome from the analysis was that three main factors could be identified. The first identified factor is that CockroachDB had a layered architecture and that it needed to translate SQL queries into a set of key-value operations. The second one is that the databases makes use of different storage engines, which in turn can have differences in performance. The third and final identified factor is that MySQL, which was integrated with Vitess, had existed for a longer period of time compared to CockroachDB. Which indicates that the database probably has been more optimized over the years.

En jämförande studie av JDBC och Hibernate med avseende på användbarhetPersson, Henrik, Nilsson, Andreas January 2010 (has links)
Två grundläggande paradigm inom datavetenskap är objektorienterad programmering och relationsdatabasteknik. En kombinering av applikationer gjorda i ett objektorienterat programmeringsspråk med den beständighet och funktionalitet som ges av relationsdatabaser är en möjlig vidareutveckling av ens kunskaper inom dessa områden. Kombinationen av dessa båda förutnämnda paradigm innebär åtminstone ett problem som uppkommer då en relationsdatabas lagrar data i tabeller och en objektorienterad applikation lagrar data i objekt. Detta problem kallas objekt/relations paradigmens missanpassning. På grund av detta problem så måste kopplingen mellan paradigmen skötas av ett ramverk av något slag. I vår rapport så undersöker vi två av de ramverk som behandlar kopplingen mellan paradigmen. Specifikt i våran studie kommer vi att fokusera på kvalitetsattributet användbarhet. De ramverk som vi undersöker heter Java Database Connectivity (JDBC) och Hibernate. Båda dessa verktyg är skapade för det objektorienterade programmeringsspråket Java. / Two of the fundamental paradigms within computer science are object oriented programming and relational databases. A combination of an object oriented application with the persistence and functionality provided by relational databases is a further development of one’s knowledge within these areas. The combination of the two aforementioned paradigms will yield at least one problem, which occurs because in a database data is stored in tables whereas an object oriented application stores data in objects. This problem is called the object/relational paradigm mismatch. Because of this problem the connection between the paradigms must be handled by some kind of framework. In our report we investigate two of the frameworks which handle the connection between the paradigms. Specifically in our study we will focus on the quality attribute usability of the two frameworks and conduct a comparison between these two. The frameworks we investigate are called Java Database Connectivity (JDBC) and Hibernate. Both of these tools are created for the object oriented programming language Java.

Um modelo de hipertexto para apoio ao ensino mediado pela Web / A hypertext model to support Web-mediated teachingLeiva, Willie Dresler 12 September 2003 (has links)
Atualmente há uma demanda crescente por aplicações hipermídia baseadas na WWW (World Wide Web), conhecidas como WIS (Web Information Systems). Esse novo tipo de aplicação apresenta requisitos adicionais aos sistemas de software clássicos, o que resulta na necessidade de investigar modelos mais adequados para apoiar o seu desenvolvimento. Em especial, os sistemas para apoio ao EaD (Ensino a Distância) baseados na Web apresentam características e requisitos ainda mais específicos. Os modelos atuais para modelagem e especificação de hiperdocumentos não são completamente adequados para representar características deste domínio, como a necessidade de acompanhamento dos aprendizes e a realização de avaliações diagnósticas e formativas. Isso motivou a proposta de um modelo para apoiar WISs voltados especificamente para EaD, denominado MDE (Modelo para Documentos Educacionais), que estende o modelo HMBS (Hyperdocument Model Based on Statecharts) para a descrição de conteúdo nesse domínio. O MDE adota como modelo formal subjacente uma variante da técnica Statecharts, cuja estrutura e semântica operacional possibilitam especificar a estrutura organizacional e a semântica navegacional de hiperdocumentos complexos. Adicionalmente, foi integrada ao MDE a técnica de mapeamento conceitual, que acrescenta um significado educacional aos grafos hierárquicos. Dessa forma, o modelo apresenta como pontos fortes a possibilidade de captar várias informações relevantes do comportamento do usuário no estudo do material disponível on-line e a disponibilização desses dados ao instrutor, como importante apoio à avaliação formativa. Como prova de conceito, foi desenvolvido o protótipo de um ambiente para autoria e oferecimento de cursos denominado ATEnA (Ambiente para Treinamento, Ensino e Aprendizagem). Esta tese apresenta também avaliações conceituais e práticas do modelo e do protótipo desenvolvidos. / There is an increasing demand for hypermedia applications based on the WWW (World Wide Web), known as Web Information Systems (WIS). These applications present specific requirements in addition to those of traditional software systems, thus fostering the need for investigating suitable models to support their development. In particular, systems for Distance Education based on the Web present very specific characteristics and requirements. Current models for hyperdocument modeling and specification are not completely suitable for representing domain specific characteristics such as the need of tracking student progress and evaluating their learning process through diagnostic and formative assessments. This scenario motivated the proposal of a model to support WISs targeted at distance education, called MDE (Model for Distance Education). MDE extends the HMBS (Hyperdocument Model Based on Statecharts) hyperdocument model to describe hypertext content in the educational domain. It adopts as its underlying model a variant of the Statecharts formal specification technique, whose organizational structure and operational semantics allows defining the organizational structure and navigational semantics of complex hyperdocuments. MDE also incorporates the technique of conceptual mapping, that adds educational meaning to hierarchical graphs. MDEs major strengths are thus the ability to capture relevant information about user behavior when studying on-line educational material and make such information available to the teacher / instructor in order to support formative assessment of students. As a proof of concept, the prototype of an environment for authoring and offering distance courses based on MDE has been developed, called ATEnA (Adaptive Training Environment with Support for Assessment). The results of practical and conceptual evaluations of the model and system developed are also presented in this thesis.

Controle eletrônico das etapas do processo de planejamento de pacientes em radioterapia / Electronic control of the steps of the planning process of patients in radiotherapyBrito, Carlos de 20 October 2017 (has links)
Em diversos serviços de radioterapia brasileiros há a premente necessidade de sistematização de processos que ainda hoje, mesmo com acesso à tecnologia da informação, é realizada manualmente. Este fato acontece com o controle dos pacientes em planejamento radioterápico onde os dados de todas as etapas do processo são inseridos em um quadro físico conforme executadas. Esses dados consistem desde o agendamento da tomografia de planejamento até a liberação do mesmo para o tratamento. O objetivo deste estudo é o desenvolvimento de um software para controle eletrônico de pacientes em processo de planejamento radioterápico, substituindo o quadro físico utilizado atualmente. Foi utilizado para este estudo a técnica de elicitação de requisitos, que resulta em um documento de requisitos que serve de base para a modelagem do sistema através de diagramas UML e modelagem conceitual do banco de dados MySql e posteriormente a utilização da técnica de mapeamento objeto relacional (MOR). A consistência nos dados permite acesso seguro e confiável à esses dados, facilita a obtenção de dados estatísticos e agiliza o processo de planejamento, já que de posse de estatísticas consistentes é possível a identificação de gargalos no processo e sua resolução com maior rapidez. O resultado deste estudo é um software e banco de dados que integra todas as informações do processo de planejamento radioterápico. / In Brazilian radiotherapy departments there is a pressing need for systematization of processes, that even today with the access of information technology is performed manually. The control of the patients in radiotherapy planning with the data of all the steps of the process are inserted in a physical board as they are executed. These data consist of scheduling since the planning tomography until the release of the patient for the treatment. The objective of this study is the development of a software for electronic control of patients in radiotherapy planning process, replacing the physical board currently used. The requirements for the elicitation technique was used for this study, which results in a requirements document that serves as the basis for modeling the system through UML diagrams and conceptual modeling of the MySql database and after using the relational object mapping technique (MOR). The data consistency allows secure and reliable access to these data, facilitates the collection of statistical data and streamlines the planning process, this consistent statistics allow the identification of limitation in the process and faster resolution. The result of this study is a software and database that integrates all the information of the radiotherapy planning process.
