Back-end development of mobile application for the collection of dietary data

Bäck, Fredrik January 2012 (has links)
Smartphones are used by incredibly many people, and in 2011 there where a total of 491.4million units soled worldwide. Smartphones are known as advanced phones, or personal digital assistants (PDAs). This makes a relevant technique for performing dietary studies when the test patients are on the move. This thesis shows how to create a back end environment for an Android application with existing techniques linked together, using MSSQL database, Visual Studio Web Service, web pages and C# classes and ASP.NET security.The back end development is used in a dietary study on Gothenburg University, but could be applied on many similar back end projects using databases and server development.Techniques used in this thesis are: REST (Representational State Transfer) -clientimplementation and development inside the Android application, using HTTP methods toset and get information from the server and database, and JSON-format to read and transfer information in an easy and understandable way, both from the Android application and from the database. FileMaker is also used in this project as a third part programme to visualise the information in the database.

Entretanto, nem sempre os dados são dispostos em arquivos tabulares de maneira adequada, o que pode causar dificuldades no momento do processamento dos dados. Dessa forma, o consórcio W3C tem trabalhado em uma proposta de especificação padrão para representação de dados em formatos tabulares. Neste contexto, este trabalho tem como objetivo geral propor uma solução para o problema de validação de arquivos de Dados Tabulares. Estes arquivos, são representados no formato CSV e descritos por metadados, os quais são representados em JSON e definidos de acordo com a especificação proposta pelo W3C. A principal contribuição deste trabalho foi a definição do processo de validação de arquivos de dados tabulares e dos algoritmos necessários para a execução desse processo, além da implementação de um protótipo que tem por objetivo realizar a validação dos dados tabulares, conforme especificado pelo W3C. Outra importante contribuição foi a realização de experimentos com fontes de dados disponíveis na Web, com o objetivo de avaliar a abordagem proposta neste trabalho. / Tabular data models have been used a lot for publishing data on the Web because of its simplicity of representation and easy manipulation. However, in some cases the data are not disposed in tabular files appropriately, which can cause data processing problems. Thus, the W3C proposed a standard specification for representing data in tabular format. In this context this work has as main objective to propose a solution to the problem of validating tabular data files, represented in CSV, files and described by metadata represented as JSON files and described, according to the specification proposed by the W3C. The main contribution of this work is the definition of a tabular data file validation process and algorithms necessary for the implementation of this process as well as the implementation of a prototype that aimed to validate tabular data as specified by the W3C. Other important contribution is the execution of experiments with data sources available on the Web with the objective to evaluate the approach proposed in this work.

Scala Web Application Toolkit / Scala Web Application Toolkit

Široký, Jan January 2013 (has links)
The thesis describes disadvantages of JavaScript in the context of big web applications and presents how they can be eliminated by compilation from a different language to JavaScript. With Scala as the source language, the thesis shows what it takes to implement such a compiler and how to solve issues that arise with the compilation process (interoperability, library distribution). On top of the compiler with a simple runtime a remote metod invocation (RPC) infrastructue is built. It also involves a dynamic client side script loader and an object graph (de)serializer. Finally the work compares the implemented toolkit to similar projects and proposes several interesting directions the toolkit can evolve into. Powered by TCPDF (www.tcpdf.org)

En prestandastudie på JSON-och XML-formaterad API-data / A performance study on JSON- and XML-formatted API-data

Larsson, Andreas January 2017 (has links)
Den här rapporten avser undersöka effekterna olika representationsmetoder av samma data har på det API som genererar datan, samt klienten som tar emot och bearbetar den. För syftet har formaten JSON och XML valts. För att analysera påverkan på API:et och klienten utvecklades ett API för att testerna skulle ge realistiska resultat. En enkel klien-themsida i JavaScript utvecklades vars uppgift var att begära data från API:et som sedan bearbetades till JSON- eller XML-objekt beroende på vilket test som kördes. Testerna sep-arerades i två scenarion, där datamängden för de två scenarierna var stor respektive liten, representerat som JSON eller XML. Klienten loggade den tid det tog från att programmet startades till att samtliga svar hade bearbetats. API-servern mätte den tid det tog från att servern mottog klientens förfrågan till att ett svar var redo att returneras. Servern mätte också systemets CPU- och minnesanvändning. Studien visade att JSON-formaterad data överlag resulterade i en mer effektiv operation. I samtliga testfall var bearbetningstiden för både klient och API-server lägre för JSON-formaterad data. Däremot visade testerna också att XML-formaterad data förbrukade en marginellt mindre andel av systemets resurser vid bearbetning av små datamängder. För samma testfall var dock bearbetningstiden av den JSON-formaterade datan fortfarande lägre. / This paper aims to analyze the effects different data representation techniques have on the API generating the data, and the client receiving and processing it. For this purpose, the formats JSON and XML was chosen. In order to analyze the effects, an API was developed in order to generate realistic results. A simple client JavaScript website was created which requested the API for data in which it processed its response to a JSON- or XML-object depending on which test was conducted. The tests were separated in two sce-narios, where the used dataset was large or small respectively, represented in either JSON orXML. The client logged the time it took from the test’s beginning until all responses had been processed. The API-server measured the time it took from receiving the request until it was returned, as well as the system’s CPU- and virtual-memory usage. The study found that JSON-formatted data overall resulted in a more efficient opera-tion. In all test cases the processing time for both the client and server were smaller for the JSON-formatted data. However, for small datasets, the study showed that the XML-formatted data used a marginally smaller portion of the system’s resources, although the JSON-formatted data was still processed quicker.

Fog Protocol and FogKit: A JSON-Based Protocol and Framework for Communication Between Bluetooth-Enabled Wearable Internet of Things Devices

Lewson, Spencer 01 June 2015 (has links)
Advancements in technology have brought about a wide variety of devices, such as embedded devices with sensors and actuators, personal computers, smart devices, and health devices. Many of these devices are categorized as “wearables,” meaning that they are intended to be carried and used on one’s body. As this category increases in popularity and functionality, developers will need a convenient way for these devices to communicate with each other and store information in a standardized and ecient manner. The Fog protocol and FogKit framework developed and demonstrated for this thesis address these issues by providing a set of powerful features, including data posting, data querying, event notifications, and network status requests. These features are defined as convenient JSON formatted messages which can be communicated between Bluetooth peripherals using an iOS device running FogKit as router and server.

Développement d'applications Web avec des composants tiers / Web application development with third-party components

Cao, Hanyang 05 February 2019 (has links)
Les applications Web sont très populaires et l'utilisation de certaines d'entre elles (p. ex. Facebook, Google) fait de plus en plus partie de nos vies. Les développeurs sont impatients de créer diverses applications Web pour répondre à la demande croissante des gens. Pour construire une application Web, les développeurs doivent connaître quelques technologies de programmation de base. De plus, ils préfèrent utiliser certains composants tiers (tels que les bibliothèques côté serveur, côté client, services REST) dans les applications web. En incluant ces composants, ils pourraient bénéficier de la maintenabilité, de la réutilisabilité, de la lisibilité et de l'efficacité. Dans cette thèse, nous proposons d'aider les développeurs à utiliser des composants tiers lorsqu'ils créent des applications web. Nous présentons trois obstacles lorsque les développeurs utilisent les composants tiers: Quelles sont les meilleures bibliothèques JavaScript à utiliser? Comment obtenir les spécifications standard des services REST? Comment s'adapter aux changements de données des services REST? C'est pourquoi nous présentons trois approches pour résoudre ces problèmes. Ces approches ont été validées par plusieurs études de cas et données industrielles. Nous décrivons certains travaux futurs visant à améliorer nos solutions et certains problèmes de recherche que nos approches peuvent cibler. / Web applications are highly popular and using some of them (e.g., Facebook, Google) is becoming part of our lives. Developers are eager to create various web applications to meet people's increasing demands. To build a web application, developers need to know some basic programming technologies. Moreover, they prefer to use some third-party components (such as server-side libraries, client-side libraries, REST services) in the web applications. By including those components, they could benefit from maintainability, reusability, readability, and efficiency. In this thesis, we propose to help developers to use third-party components when they create web applications. We present three impediments when developers using the third-party components: What are the best JavaScript libraries to use? How to get the standard specifications of REST services? How to adapt to the data changes of REST services? As such, we present three approaches to solve these problems. Those approaches have been validated through several case studies and industrial data. We describe some future work to improve our solutions, and some research problems that our approaches can target.

Partnerių vieša API ir jos panaudojimas WHMCS modulyje / Partners' public API and its usage from WHMCS module

Valinskis, Mindaugas 16 July 2014 (has links)
Įmonė UAB „Duomenų Centras“ nuomoja serverius jau 13 metų. Atlikus tyrimus paaiškėjo, kad įmonė eksportuoja apie 75% savo paslaugų į daugiau nei 130 pasaulio šalių. Prie šio rezultato labai prisidėjo Duomenų Centro partneriai iš Lietuvos ir kitų šalių. Partneris – tai svarbiausias klientas, kuris pritraukia kitus naujus klientus. Per įmonės gyvavimo metus visas perpardavinėjimo ir partnerių klientų paslaugų valdymo procesas buvo per elektorinį paštą - tai užtrunka, tokios paslaugos nėra itin patrauklios šiuolaikinėje interneto rinkoje. Todėl dokumente atskleidžiama „partnerių programa“, bei API posistemė, kuri leidžia įmonės partneriams vykdyti su paslaugomis susijusias funkcijas. / The modern data center of Balticservers have been selling their services now for 13 years. The research revealed that the company exports 75% of its services to more than 130 countries worldwide. Moreover, the company has partners from Lithuania and many other countries. The product has been designed for partners that optimizes the process of reselling Balticservers services. It offers a WHMCS module which allows an easy creation and customization of services that are desired to be resold from Balticservers. Also, this includes an API communication between two separated systems that are WHMCS and Korys which Balticservers are currently developing and using in their daily work. API has been developed by using PHP scripting language, cURL and JSON technologies. The document exposes a few similar API systems’ comparison, product requirement specification, architecture’s specification, testing protocol and partners API documentation.

Visualisering av storadatamängder i en webbläsare / Visualization of big data in a webbrowser

Amri, Abdurrahman, Hashosh, Wameedh January 2016 (has links)
Scania AB äger komplicerade testsystem som genererar stora och invecklade mängder av data. Ett av dessa testsystem är Hardware-In-the-Loop riggar (HIL) som testar elektriska system och genererar elektriska signaler samt resultat av de utförande testerna. Datat från dessa elektriska signaler skall sedan sparas i JSON-filer. För att dra nytta av Datat måste de sparas i en lämplig databas som kan be-handla denna data på ett bra sätt.Data från elektriska signaler beskriver olika fordonsegenskaper över tiden, vilket kan betraktas som en multivariat tidsserie.I det nuvarande systemet lagras och visualiseras data på ett ineffektivt sätt. Syftet med den första delen av studien är att undersöka 4 relevanta databaser som kan hantera JSON-filer. Den andra delen av detta arbete handlar om metoder för visua-lisering av signaler, det vill säga hur signaler kan representeras i form av grafer.Undersökningsresultat visade att två databaser är mer kvalificerade att ersätta den nuvarande databasen. CouchDB och PostgreSQL testades för att mäta deras pre-standa när det gäller lagring och hämtning av data.Testresultatet visade att CouchDB har högre prestanda för datahämtning än Post-greSQL. Därefter utvecklades en prototyp vars uppdrag var att visualisera signaler i webbläsare. / Scania AB owns the complex test systems that generate complex and large amounts of data. To take advantage of this data, it must be stored in a suitable database, de-pending on the data type. One of these test systems is Hardware-In-the-Loop which tests electrical system and produces large amounts of electrical signals. The data of these electrical signals will be saved in the form of JSON files.In the current system, these data are stored and visualized in an inefficient manner. The purpose of this study was to investigate 4 relevant databases that can handle JSON files. The second part of this work was to visualize signals in the web brow-ser.Results of investigations show that two databases were more qualified to replace the current database. CouchDB and PostgreSQL was a test-item to measure their performance in terms of response time in relation to file size and the number of signals.Results of the tests show that CouchDB has higher performance for retrieving data than PostgreSQL. Then, a prototype was developed in order to visualize the signals in the web browser.
