A Comparative Study Of MVC Architecture Model Of Open Source Server Side Scripting Language Jsp And Php For Client-Server Architecture Based Applications Development

The Model-View-Controller (MVC) architecture pattern has become a popular way to structure web applications, separating the data, presentation, and application logic into modular components. This review paper provides a comparative analysis of implementing MVC architecture using two major open-source server-side scripting languages - JavaServer Pages (JSP) and PHP. Over 10,000 open source projects utilizing JSP/Java and PHP are analyzed to compare how the languages lend themselves to the MVC pattern. The challenges and advantages of both platforms for real-world development of thin-client applications are assessed. Quantitative metrics on performance, scalability, code reuse and integration with MVC frameworks like Spring and Laravel are provided. The findings indicate strengths and weaknesses unique to both languages, with outcome being that PHP+Laravel offers faster initial development time, while JSP+Spring provides more enterprise-grade scalability. The insights can guide developers to make an informed choice between the two platforms for MVC-based, client-server application development.

The Archaeology of Qumran and the Dead Sea Scrolls by Jodi Magness

Reviewed by: The Archaeology of Qumran and the Dead Sea Scrollsby Jodi Magness Dennis Mizzi jodi magness, The Archaeology of Qumran and the Dead Sea Scrolls( 2nded.; Grand Rapids: Eerdmans, 2021). Pp. xiii + 326. Paper $29.99. This is a second edition of one of the most influential books in the field of Qumran studies. First published in 2002, Jodi Magness's The Archaeology of Qumran and the Dead Sea Scrollsbecame an instant landmark work on the subject (see the review by James R. Davila in CBQ66 [2004] 293–95). It not only made this celebrated, and often controversial(!), [End Page 340]site accessible to a general readership, but also became a must-read for academics seeking an introduction to Qumran. To this day, it remains a standard work and is widely cited by scholars across different fields. Nonetheless, scholarship on Qumran and the Dead Sea Scrolls has developed tremendously in the past two decades. In the intervening years, many new books and countless articles dealing with the archaeology of Qumran and the Scrolls have been published, and three final reports—one on Roland de Vaux's 1951–1956 excavations at Qumran (Jean-Baptiste Humbert, Alain Chambon, and Jolanta Młynarczyk, Khirbet Qumrân et Aïn Feshkha, Vol. 3a: L'archéologie de Qumrân: Reconsidération de l'interprétation; Les installations périphériques de Khirbet Qumrân; Qumran Terracotta Oil Lamps[NTOA Series archaeologica 5a; Göttingen: Vandenhoeck & Ruprecht, 2016]), another on Cave 11Q (Jean-Baptiste Humbert and Marcello Fidanzio, eds., Khirbet Qumrân et Aïn Feshkha, Vol. 4a: Qumrân Cave 11Q: Archaeology and New Scroll Fragments[NTOA Series archaeologica 8a; Göttingen: Vandenhoeck & Ruprecht, 2019]), and the other on Yitzhak Magen and Yuval Peleg's 1994–2004 investigations of the site (Yitzhak Magen and Yuval Peleg, Back to Qumran: Final Report (1993–2004)[JavaServer Pages 18; Jerusalem: Israel Antiquities Authority; Civil Administration of Judea and Samaria, 2018])—have also appeared in print. M. herself has since updated or revised some of her previous conclusions. A second edition of this most important work, therefore, was not only inevitable but highly anticipated. The book's format and structure follow the template of the original. It has the same number of chapters (ten), all of which retain the same title, and bibliographic notes are appended at the end of each one. This keeps the text clean but requires additional work from readers, who have to hunt down certain bibliographic items. The chapters are organized thematically, starting with an introduction on archaeology as a field of study (chap. 1); a summary of early explorations of Qumran, the discovery of the Dead Sea Scrolls, and the early history of research (chap. 2); and an overview of the Scrolls, the sectarian communities they depict, and their relation to Qumran (chap. 3). These are followed by chapters on the site's building(s) and occupation phases (chap. 4); the pottery and architecture (chap. 5); the remains of communal meals, a toilet, and notions of sacred space at Qumran (chap. 6); miqwāʾôt(Jewish ritual baths) (chap. 7); the cemetery and the question of women at the site (chap. 8); and the inhabitants' clothing, their views on the temple tax, and their anti-Hellenizing attitudes (chap. 9). The final chapter goes beyond the site to explore the nearby settlements of ʿEin Feshkha and ʿEin el-Ghuweir and their possible connection to Qumran (chap. 10). Revisions and updates are scattered throughout the book and integrated into the individual chapters. The basic thesis of the first edition remains unchanged. M. mounts a strong and convincing case in favor of seeing Qumran as a sectarian/Essene settlement related to the large collection of scrolls found in the surrounding caves. The corollary is that Qumran presents us with a unique opportunity to bring texts and archaeology into conversation, allowing us to illumine the daily life of the Qumran sectarians in a holistic manner and gain insights that would not otherwise be possible. This is exactly what M. does, and the result is a vivid account of the site's history and its inhabitants' practices, beliefs, and worldview. Apart from updating the...

Real-Time Office Seat Allocation System using Spring MVC framework

Real-time Seat Allocation System is a web application that assists employees and employers in handling modern-day seating issues at work. Currently, seats are assigned to employees manually, which is a time-consuming process. This might cause issues if seats were not assigned or if none were available for some employees. Furthermore, during pandemics, social distance rules must be followed, making it difficult to manage the workforce. The proportion of individuals allowed in the workplace must adhere properly. As the firm grows, so does the number of employees, which necessitates the expansion of infrastructure, which costs money and time. These issues can be addressed to some extent by a shared office concept, in which employees have access to a desk and can work as needed. This article presents a responsive web application through which company employees can registerusingtheircompanyIDandreserveaseatifoneisavailableonaspecified day and time. Admins can add or remove offices, floors, and seats with certain permissions. To implement the business logic, the application uses Java, Spring MVC web framework with Tomcat server, renders the views using Java Server Pages, and uses front-end technologies like HTML, CSS, and JavaScript for the front-end design of the User Interface. The web application built promotes the concept of using a shared workspace to maximize resource use. It also aids in increasing employee productivity by providing them with workplace seating and schedule flexibility.

Computer Assisted Instruction System under Artificial Intelligence Technology

In order to promote the development of intelligent teaching system, artificial intelligence technology is combined with computer assisted instruction (CAI) system to produce intelligent CAI (ICAI), and the design of ICAI is studied in order to facilitate the application and implementation of intelligent teaching system. First, there is an introduction of the basic concepts, related theories, and implementation principles of ICAI. Then, the requirements of ICAI are analyzed in detail on the basis of studying the relevant technologies required by ICAI, including the functional and non-functional requirements. The subsystem is set based on the different needs of the target users (administrator, teacher, and student users). Finally, the general and functional structure of ICAI are designed, and there are tests for the system functions. The results show that the system takes Java Server Pages (JSP) as the development language, Struts2 as the technical framework, and SQL Server 2008 as the back-end database, which realizes a teaching platform mainly for teachers, students, and administrators. After testing, the overall operation of the system is good, and the functional test results of the login module, homework release, and learning resource upload meet the software design requirements. The response time of the system prolongs, the number of users who can’t successfully log in grows, and the utilization of server central procession unit (CPU) and memory utilization both increase, which are caused by the increasing number of concurrent users. The results indicate that the combination of CAI and artificial intelligence (AI) technology can meet students’ online teaching demands, break the time-space limitation of traditional teaching, and provide important reference value for the reform of teaching mode and the improvement of teaching quality

An Improved Methodology for Collaborative Construction of Reusable, Localized, and Shareable Ontology

Interlocking Institutional Worlds (IWs) is a concept explaining the need to interoperate between institutions (or players), to solve problems of common interest in a given domain. Managing knowledge in the IWs domain is complex; however, promoting knowledge sharing based on standards and common terms agreeable to all players is essential and is something that must be established. In this context, ontologies, as a conceptual tool and a key component of knowledge-based systems, have been used by organizations for effective knowledge management, better decision-making, and interoperability among diverse institutions of an IWs domain. The development of ontology involves structural and logical complexity, and requires a well-designed, mature, and widely accepted methodology, to ensure its reliability. Many methodologies for ontology development have been proposed by several researchers; however, most of the developed methodologies have not included several important phases. Furthermore, several methodologies have not provided the complete details of the techniques and activities involved in the ontology construction process. Fewer details make it difficult to follow a methodology for designing ontologies. This study aims to compare existing methodologies based on sixteen important criteria and proposes an improved methodology for ontology development for IWs domains. The proposed methodology has included several important phases such as the Estimation of Human Resources, Re-engineering and Re-using of Resources, Collaborative Ontology Construction, the Conceptualization of both Endurants and Perdurants, Localization of an Ontology, Ontology Integration and Merging, Support for Interoperability, Versioning of an Ontology, and Ontology Population. The proposed methodology has been applied to design an OntoWM domain ontology for the Waste Management (WM) domain. The evaluation of the proposed methodology has been made by utilizing the designed OntoWM domain ontology in an ontology-based web application called SmartBinAnalytics. SmartBinAnalytics has been built using OntoWM, Java Server Pages (JSP), Jena Application Programming Interface (API), and MySQL. The proposed methodology can be used for the construction of domain ontologies in any IWs domain.

Extending Abstract Interpretation to Dependency Analysis of Database Applications

Dependency information (data- and/or control-dependencies) among program variables and program statements is playing crucial roles in a wide range of software-engineering activities, e.g., program slicing, information flow security analysis, debugging, code-optimization, code-reuse, code-understanding. Most existing dependency analyzers focus on mainstream languages and they do not support database applications embedding queries and data-manipulation commands. The first extension to the languages for relational database management systems, proposed by Willmor et al. in 2004, suffers from the lack of precision in the analysis primarily due to its syntax-based computation and flow insensitivity. Since then no significant contribution is found in this research direction. This paper extends the Abstract Interpretation framework for static dependency analysis of database applications, providing a semantics-based computation tunable with respect to precision. More specifically, we instantiate dependency computation by using various relational and non-relational abstract domains, yielding to a detailed comparative analysis with respect to precision and efficiency. Finally, we present a prototype $\sf{ semDDA}$ semDDA , a sem antics-based D atabase D ependency A nalyzer integrated with various abstract domains, and we present experimental evaluation results to establish the effectiveness of our approach. We show an improvement of the precision on an average of 6 percent in the interval, 11 percent in the octagon, 21 percent in the polyhedra and 7 percent in the powerset of intervals abstract domains, as compared to their syntax-based counterpart, for the chosen set of Java Server Page (JSP)-based open-source database-driven web applications as part of the GotoCode project.

LEPStr: A database for Mycobacterium leprae short tandem repeats

Abstract Short tandem repeats are short arrays of nucleotide sequences, and they have vital roles in many biological processes, including modulation of transcription, enhancement of gene expression, adaptation to a particular environment, and link to autosomal recessive diseases. Short tandem repeats are also used to study DNA fingerprinting for conservation genetics, taxon specific identification of species, infectious disease transmission dynamics, and marker assisted selection. In the present study we developed an online database viz., LEPStr, for short tandem repeat of Mycobacterium leprae, along with copy number variation, gene of occurrence, and primers to amplify the tandem repeat regions. The whole genome sequence of M. leprae, MRHRU-235, accession no CP029543, was used as the template for screening of STRs with the tandem repeat finder. A layout of the database of LEPStr was developed using JavaScript (JS) and Java Server Pages (JSP) and implemented in MySQL database. A user-friendly interactive and free-to-use web interface was developed to browse Minisatellites and Microsatellites of M. leprae, along with primers to amplify the repeat regions. The LEPStr is an online database which is embedded with all short tandem repeats of M. leprae. LEPStr would be helpful in the typing of M. leprae strains, tracing the transmission dynamics of leprosy.
