INTRODUCTION TO ZEND FRAMEWORK

A software framework provides the skeleton of an application that can be customized by an application developer. Like software libraries, software frameworks aid the software developer by containing source code that solves problems for a given domain and provides a simple API. However, while a code library acts like a servant to other programs, software frameworks reverse the master/servant relationship. This reversal, called inversion of control, expresses the essence of software frameworks. A web application framework is a software framework that is designed to support the development of dynamic websites, Web applications and Web services. The framework aims to alleviate the overhead associated with common activities used in Web development. For example, many frameworks provide libraries for database access, templating frameworks and session management, and often promote code reuse.Zend Framework

Cyberaide JavaScript: A Web Application Development Framework for Cyberinfrastructure

This thesis work introduces a service oriented architecture based Grid abstraction framework that allows users to access Grid infrastructure through JavaScript. Such a framework integrates well with other Web 2.0 technologies since it provides JavaScript toolkit to build web applications. The framework consists of two essential parts. A client Application Programming lnterface (API) to access the Grid via JavaScript and a full service stack in server side through which the Grid access is channeled. The framework uses commodity Web service standards and provides extended functionality such as asynchronous task management, file transfer, etc. The availability of this framework simplifies not only the development of new services, but also the development of advanced client side Grid applications that can be accessed through Web browsers. The effectiveness of the framework is demonstrated by providing an Grid portal example that integrates a variety of useful services to be accessed through a JavaScript enabled client desktop via a Web browser, as well as the opensocial gadgets for Grid task management and file transfer. Overall, Grid developers will have another tool at their disposal that projects a simpler way to distribute and maintain cyberinfrastructure related software, while simultaneously delivering advanced interfaces and integrating social services for the scientific community

A framework for deriving semantic web services

Web service-based development represents an emerging approach for the development of distributed information systems. Web services have been mainly applied by software practitioners as a means to modularize system functionality that can be offered across a network (e.g., intranet and/or the Internet). Although web services have been predominantly developed as a technical solution for integrating software systems, there is a more business-oriented aspect that developers and enterprises need to deal with in order to benefit from the full potential of web services in an electronic market. This ‘ignored’ aspect is the representation of the semantics underlying the services themselves as well as the ‘things’ that the services manage. Currently languages like the Web Services Description Language (WSDL) provide the syntactic means to describe web services, but lack in providing a semantic underpinning. In order to harvest all the benefits of web services technology, a framework has been developed for deriving business semantics from syntactic descriptions of web services. The benefits of such a framework are two-fold. Firstly, the framework provides a way to gradually construct domain ontologies from previously defined technical services. Secondly, the framework enables the migration of syntactically defined web services toward semantic web services. The study follows a design research approach which (1) identifies the problem area and its relevance from an industrial case study and previous research, (2) develops the framework as a design artifact and (3) evaluates the application of the framework through a relevant scenario

AMP: A Science-driven Web-based Application for the TeraGrid

The Asteroseismic Modeling Portal (AMP) provides a web-based interface for astronomers to run and view simulations that derive the properties of Sun-like stars from observations of their pulsation frequencies. In this paper, we describe the architecture and implementation of AMP, highlighting the lightweight design principles and tools used to produce a functional fully-custom web-based science application in less than a year. Targeted as a TeraGrid science gateway, AMP's architecture and implementation are intended to simplify its orchestration of TeraGrid computational resources. AMP's web-based interface was developed as a traditional standalone database-backed web application using the Python-based Django web development framework, allowing us to leverage the Django framework's capabilities while cleanly separating the user interface development from the grid interface development. We have found this combination of tools flexible and effective for rapid gateway development and deployment.Comment: 7 pages, 2 figures, in Proceedings of the 5th Grid Computing Environments Worksho

Cross Platform Web Application Development Using ASP.NET Core

Cross platform software development is a practice of developing an application which can be run on more than one OS platform such as Windows, Linux, MacOS, etc. Today’s web application development trend is moving towards cross platform frameworks as we can see that the types of web application we build today are very different from the ones we used to build a decade ago. With the rise of cloud-based systems, mobile technologies, and extensive web interactive environments, web applications today are becoming more dynamic and consequently the web application development process have made tremendous advances. Web applications are expected to be highly performant and scalable. To address the rapidly changing web development landscape and performance scalability requirements there is a need of a powerful framework. ASP.NET Core is one such framework which incorporates modern approach for building web applications. It provides cross-platform capabilities i.e. having a single code base for the application and running it on different platforms. It also provides high performance and modular infrastructure. This report presents a software development process of cross platform web application in which it explains design, development and deployment of ASP.NET Core web application. A timesheet management system which is developed as a part of this project, helps to manage timesheet operations of an organization and provides efficient way to track time used by employees in various projects and their time offs. The application is called MyTime. It is built utilizing ASP.NET Core MVC Framework and Entity Framework Core which is deployed on two platforms; Windows and Linux. This report describes the detail steps of deployment for both platforms. It provides an overall idea of how ASP.NET Core framework can be utilized to build a web application with cross platform capabilities

Semantic Transformation of Web Services

Web services have become the predominant paradigm for the development of distributed software systems. Web services provide the means to modularize software in a way that functionality can be described, discovered and deployed in a platform independent manner over a network (e.g., intranets, extranets and the Internet). The representation of web services by current industrial practice is predominantly syntactic in nature lacking the fundamental semantic underpinnings required to fulfill the goals of the emerging Semantic Web. This paper proposes a framework aimed at (1) modeling the semantics of syntactically defined web services through a process of interpretation, (2) scop-ing the derived concepts within domain ontologies, and (3) harmonizing the semantic web services with the domain ontologies. The framework was vali-dated through its application to web services developed for a large financial system. The worked example presented in this paper is extracted from the se-mantic modeling of these financial web services

Knowledge infrastructures for software service architectures

Software development has become a distributed, collaborative process based on the assembly of off-the-shelf and purpose-built components or services. The selection of software services from service repositories and their integration into software system architectures, but also the development of services for these repositories requires an accessible information infrastructure that allows the description and comparison of these services. General knowledge relating to software development is equally important in this context as knowledge concerning the application domain of the software. Both form two pillars on which the structural and behavioural properties of software services can be addressed. We investigate how this information space for software services can be organized. Focal point are ontologies that, in addition to the usual static view on knowledge, also intrinsically addresses the dynamics, i.e. the behaviour of software. We relate our discussion to the Web context, looking at the Web Services Framework and the Semantic Web as the knowledge representation framework

USPOREDBA FRONT END FRAMEWORKA ZA IZRADU WEB-APLIKACIJA

Modern web applications, due to the functionalities they provide in their user interfaces, have a complex program structure. Manually writing a program code, due to the complexity of the entire application, can result in uneven quality and content of individual application parts. Maintaining such developed applications is more difficult. Because of this, web applications are often developed by using different frameworks. A framework allows structuring, simpler and more uniform program script writing, and thus easier web application maintenance. There are various frameworks that can be used in the development of web applications, for different parts of the application. Those analyzed in this paper are used in the development of front end parts of web applications. According to their design, a web application can be developed as the Multi Page (MPA) or the Single Page (SPA). This paper explains the difference between MPA and SPA web applications. The advantages and disadvantages of MPA are demonstrated in relation to SPA web applications. Required characteristics that the framework should have in order to be optimized for creating MPA and SPA web applications are set. The hypothesis has been tested: There is a framework that is optimized for the development of both MPA and SPA applications. Possibilities, architecture and development techniques of a web application using front end frameworks, as well as the suitability of such frameworks for the development of MPA and SPA web applications have been analysed. Choosing a framework for the hypothesis testing has been performed based on the popularity of available frameworks. The required characteristics have been analyzed on the three most popular frameworks: Angular, Vue.js and React-js. It has been shown that the Vue.js framework is the most optimized framework for the development of both MPA and SPA applications.Moderne web-aplikacije, zbog funkcionalnosti koje omogućuju u korisničkom sučelju, imaju složenu programsku strukturu. Ručno pisanje programskog koda zbog složenosti cijele aplikacije može rezultirati neujednačenom kvalitetom i sadržajem pojedinih aplikacijskih djelova. Održavanje tako razvijanih aplikacija otežano je. Zbog toga se web-aplikacije često razvijaju korištenjem različitih frameworka. Framework omogućuje strukturiranje, jednostavnije i ujednačenije pisanje programskog koda, te time olakšava održavanje web-aplikacije. Postoji puno frameworka koji se mogu koristiti u razvoju web-aplikacija, i to za različite dijelove aplikacije, a oni analizirani u ovom radu koriste se u razvoju front end dijela web-aplikacije. Prema načinu izvođenja webaplikacije mogu biti Multi Page (MPA) ili Single Page (SPA). U radu je objašnjena različitost između MPA i SPA web-aplikacija. Pokazane su prednosti i nedostatci MPA u odnosu na SPA web-aplikacije. Postavljene su zahtijevane karakteristike frameworka koji je optimiziran za izradu MPA i SPA web-aplikacija. Testirana je hipoteza: Postoji framework koji je prilagođen za izradu i MPA i SPA aplikacija. Analizirane su mogućnosti, arhitektura i načini razvoja web-aplikacija pomoću front end frameworka te prilagođenost takvih frameworka za razvoj MPA i SPA web-aplikacija. Izvršen je odabir frameworka za testiranje hipoteze prema popularnosti na tržištu. Zahtijevane karakteristike analizirane su na 3 najpopularnija frameworka: Angular, Vue.js i React-js. Pokazano je da je Vue.js framework najoptimiziraniji framework za izradu i MPA i SPA aplikacija
