Curated databases have become important sources of information across several scientific disciplines, and as the result of manual work of experts, often become important reference works. Features such as provenance tracking, archiving, and data citation are widely regarded as important features for the curated databases, but implementing such features is challenging, and small database projects often lack the resources to do so. A scientific database application is not just the relational database itself, but also an ecosystem of web applications to display the data, and applications which allow data curation. Supporting advanced curation features requires changing all of these components, and there is currently no way to provide such capabilities in a reusable way. Cross-tier programming languages allow developers to write a web application in a single, uniform language. Consequently, database queries and updates can be written in the same language as the rest of the program, and it should be possible to provide curation features via program transformations. As a step towards this goal, it is important to establish that realistic curated databases can be implemented in a cross-tier programming language. In this article, we describe such a case study: reimplementing the web frontend of a realworld scientific database, the IUPHAR/BPS Guide to PHARMACOLOGY (GtoPdb), in the Links cross-tier programming language. We show how programming language features such as language-integrated query simplify the development process, and rule out common errors. Through an automated functional correctness evaluation, we show that the Links implementation correctly implements the functionality of the official version. Through a comparative performance evaluation, we show that the Links implementation performs fewer database queries, while the time neededto handle the queries is comparable to the official Java version. Furthermore, while there is some overhead to using Links because of its comparative immaturity compared to Java, the Links version is usable as a proof-of-concept case study of cross-tier programming for curated databases.

Curated databases have become important sources of information across several scientific disciplines, and as the result of manual work of experts, often become important reference works. Features such as provenance tracking, archiving, and data citation are widely regarded as important features for the curated databases, but implementing such features is challenging, and small database projects often lack the resources to do so. A scientific database application is not just the relational database itself, but also an ecosystem of web applications to display the data, and applications which allow data curation. Supporting advanced curation features requires changing all of these components, and there is currently no way to provide such capabilities in a reusable way. Cross-tier programming languages have been proposed to simplify the creation of web applications, where developers can write an application in a single, uniform language. Consequently, database queries and updates can be written in the same language as the rest of the program, and at least in principle, it should be possible to provide curation features reusably via program transformations. As a first step towards this goal, it is important to establish that realistic curated databases can be implemented in a cross-tier programming language. In this paper, we describe such a case study: reimplementing the web front end of a real world scientific database, the IUPHAR/BPS Guide to Pharmacology (GtoPdb), in the Links cross-tier programming language. We show how programming language features such as language-integrated query simplify the development process, and rule out common errors. Through a comparative performance evaluation, we show that the Links implementation performs fewer database queries, while the time needed to handle the queries is comparable to the Java version.

Access Control Policies

The software security issue is being paid great attention from the software development community as security violations have emerged variously. Developers often use access control techniques to restrict some security breaches to software systems’ resources. The addition of authorization constraints to the role-based access control model increases the ability to express access rules in real-world problems. However, the complexity of combining components, libraries and programming languages during the implementation stage of web systems’ access control policies may arise potential flaws that make applications’ access control policies inconsistent with their specifications. In this paper, we introduce an approach to review the implementation of these models in web applications written by Java EE according to the MVC architecture under the support of the Spring Security framework. The approach can help developers in detecting flaws in the assignment implementation process of the models. First, the approach focuses on extracting the information about users and roles from the database of the web application. We then analyze policy configuration files to establish the access analysis tree of the application. Next, algorithms are introduced to validate the correctness of the implemented user-role and role-permission assignments in the application system. Lastly, we developed a tool called VeRA, to automatically support the verification process. The tool is also experimented with a number of access violation scenarios in the medical record management system.

Extract Information

JavaScript Object Notation is a text-based data exchange format for structuring data between a server and web application on the client-side. It is basically a data format, so it is not limited to Ajax-style web applications and can be used with API’s to exchange or store information. However, the whole data never to be used by the system or application, It needs some extract of a piece of requirement that may vary person to person and with the changing of time. The searching and filtration from the JSON string are very typical so most of the studies give only basics operation to query the data from the JSON object. The aim of this paper to find out all the methods with different technology to search and filter with JSON data. It explains the extensive results of previous research on the JSONiq Flwor expression and compares it with the json-query module of npm to extract information from JSON. This research has the intention of achieving the data from JSON with some advanced operators with the help of a prototype in json-query package of NodeJS. Thus, the data can be filtered out more efficiently and accurately without the need for any other programming language dependency. The main objective is to filter the JSON data the same as the SQL language query.

This chapter presents the WDP (Web Design Perspectives-based Usability Evaluation), an inspection technique specifically designed to assess the usability of Web applications. This technique combines Web design perspectives and the heuristic evaluation method proposed by Nielsen (1994b). In addition to describing the components of the WDP technique this chapter also illustrates its use in practice by means of an industrial case study where the technique is applied to inspect a real Web application. In this case study, developers and requirement assessment staff applied the WDP technique to evaluate the usability of modules developed from scratch for a Web application. The results of this case study indicate the feasibility of performing usability inspections with the participation of a software project’s stakeholders, even when stakeholders are not usability experts.

The Web

Undeniably the most favored web scripting language is PHP. Almost 80% of the internet’s server-side web applications are written in PHP which includes big giants like WordPress, Wikipedia, and Facebook. In present-day, at an accelerating pace, the quantity of digital content is burgeoning. A heterogeneous set of users' devices is being amassed by these contents and administering these contents manually is an infeasible solution engendering an increasing set of problems. A solution to this problem would be to switch to a web programming language, which can be compiled. We are describing an easy to deploy and a continuous conversion mechanism for converting existing Web 2.0 PHP application systems into Facebook’s HHVM supported Hack server-side application systems. We are trying to use the power of Hack language and amplify the performance of existing PHP server-side applications. Instead of interpreting all of your code Hack translates it to assembly and runs that instead, which can lead to an immense amount of increase in performance. We are using Hacktificator, a tool developed by Facebook Developers and our demo web application running on HHVM to test and convert user’s existing PHP codebase to Hack language. With this proposed methodology we do not have to make any change to existing codebase manually or hire new engineers for the conversion, nor do we have to take down our live systems. Conversion can be done on the fly and will result in approximately 2x to 20x better performance. The availability of this tool can save costs for manual conversion, save time as well as improve the user experience of websites with better performance

From the physical book store to the online bookstore, business owners find a way to meet the demands of their prospective customers. The daily advancement in technology has brought about a huge change the operation of e-commerce. The development of the Progressive Web Applications (PWA) by Google has caused a revolution in mobile development. Using an online bookstore as a case study, this research work presents a PWA architectural framework that can be adopted by any e-commerce applications. This was achieved after a systematic review of existing online bookstore models was carried out – identifying the gaps which will serve as strengths for the proposed model. Also, the emerging technology of PWA was critically reviewed to solidify the proposed model. Adoption of the model will avoid current issues faced the world of mobile development especially code fragmentation. However, exploring the payment gateways and modules will help solidify the model.

In the previous chapter, we created an m-business application using ColdFusion. Besides ColdFusion, many other development tools can be used to develop m-business applications. Visual Studio .NET, an integrated development environment by Microsoft, has become an increasingly popular corporate applicationdevelopment tool due to its ease of use and support for a wide range of programming languages. Besides traditional Windows and Web applications, Visual Studio .NET also allows developers to build mobile and wireless applications with relative ease. The focus of this chapter is to discuss the tools and techniques for developing wireless applications using Visual Studio .NET. Wireless applications are developed using the ASP .NET Mobile Web Application template. The template provides developers with WYSIWYG tools for creating user interfaces for various mobile devices. These tools work seamlessly with ASP.NET, which uses a form-based approach to build server-side applications for processing user requests and interacting with databases. In this chapter, we will develop a business-to-consumter wireless application using Visual Studio .NET.

Tag software is included in web applications to facilitate categorization and classification of information. Generally, freely available tag software is adapted or new code written to incorporate tagging. However, there is an absence of requirement and design document for tagging, even academically. It becomes difficult to know the features that can be included in tag software; also, not all features may be required. This chapter presents a framework for integration of tag software in web applications. The framework has four components corresponding to phases of the software development lifecycle. For requirement, a weighted requirement checklist is presented to ease requirement selection. A metric, software estimation, is defined for quantifying selected requirement. A logical design defined for design phase displays interaction of entities with users. For development, best mechanisms are suggested to web applications. Software engineering artefacts are provided to help during testing. A case study is presented where estimation and design is applied to freely available tag software.

In order to set up well-structured multitasking robot application programs careful planning is required. Robot programming languages (e.g. Karel, RAPID, Melfa, SimPro, etc.) vary from robot to robot constructor. General planning tools used in software development (e.g. UML, IDEF, etc.) require adequate professional skills and a special way of thinking such that robot programmers to apply and adapt them to the specificity of each robot programming language. Customized and intuitive planning tools of robot applications with regard to each particular programming language seem to be preferred by ordinary robot programmers and operators when facing with the development of complex robot tasks. This paper introduces such a tool in relation to the RAPIDTM programming language, specific to ABB robot models. Its effectiveness is revealed in a case study.

AbstractThe sources of information on the Web relating to Fine Art and in particular to Fine Artists are numerous, heterogeneous and distributed. Data relating to the biographies of an artist, images of their artworks, location of the artworks and exhibition reviews invariably reside in distinct and seemingly unrelated, or at least unlinked, sources. While communication and exchange exists, there is a great deal of independence between major repositories, such as museum, often owing to their ownership or heritage. This increases the individuality in the repository’s own processes and dissemination. It is currently necessary to browse through numerous different websites to obtain information about any one artist, and at this time there is little aggregation of Fine Art Information. This is in contrast to the domain of books and music, where the aggregation and re-grouping of information (usually by author or artist/band name) has become the norm. A Museum API (Application Programming Interface), however, is a tool that can facilitate a similar information service for the domain of Fine Art, by allowing the retrieval and aggregation of Web-based Fine Art Information, whilst at the same time increasing public access to the content of a museum’s collection. In this paper, we present the case for a pragmatic solution to the problems of heterogeneity and distribution of Fine Art Data and this is the first step towards the comprehensive re-presentation of Fine Art Information in a more ‘artist-centric’ way, via accessible Web applications. This paper examines the domain of Fine Art Information on the Web, putting forward the case for more Web services such as generic Museum APIs, highlighting this via a prototype Web application known as the ArtBridge. The generic Museum API is the standardisation mechanism to enable interfacing with specific Museum APIs.
