Applying MVC data model on hadoop for delivering the business intelligence

With the development and popularization of Internet, distance education has already entered the stage based on Web. Due to the shortcomings of traditional methods in developing Web application, the MVC (model-view-controller) pattern is introduced. The separation of logic programming from interface design is effectively archived by the three kinds of technology correlated with Java: JSP, Servlet and JavaBeans. This paper analyses MVC pattern. On the purpose of the unanimous solution of distance education and commercialization, an improved MVC pattern based on the conventional one is introduced. The practice of developing the distance education system proved the improved pattern is feasible.

Dance appreciation is a creative and complex spiritual activity process of the unity of feeling and understanding, affection and understanding. Development of information technology and mobile terminals provide a new way to dance appreciation. In order to develop dance appreciation video system, this paper designed it based on the MVC mode and provided technical support for software development. Firstly, studied the MVC mode, using graph represented the relationship among modes, views and controllers; and then designed layered system architecture consisting of user layer, service layer and management layer; finally, with the live video of one of the core program designed the program flow and illustrated the implementation process. The results shown that forcibly defining controller, model, view and other modules of application improved the readability of application and the reusability of code.

In recent years, the foremost of the progress area unit having issue to adapt the advanced policies and most of the approaches required customized workflow engines. This research work focuses on projecting a new changed Model-View-Controller (MVC) framework for imposing the advanced policies to dynamic workflows. The framework Model-Operations-View-Events (MOVE) is especially supported Model-View-Controller pattern that is employed to feature the dynamic sites. The controller element in MVC framework is spitted into 2 blocks namely Operations and Events owing to artifact too several codes into the controller in MVC pattern we tend to area unit going for improved MVC framework. The main aim is to style a progress processes as a template in abstract level. The progress language is employed to implement the logic and imposing any kind of policies. Additionally to the present we tend to area unit attending to value by suggests that of learning the confidentiality and it's used permits the application-specific adaptation work running instance.

Client-Server (C/S) application is always used in the existing Human Resource Management System (HRMS) as the system architecture, which has the problems of complex maintenance and poor compatibility; and cannot use professional database and development system, making the system development difficult and the data security low. To solve the above problems, the overall demand is analyzed, as well as feasibility and key technologies of the enterprise HRMS system. Then a HRMS is designed and developed, based on the user’s key functional requirements and related technologies, which is reasonable and easy to maintain. The system is supported by Browser-Server (B/S) structure, with the current popular Java 2 Platform Enterprise Edition (J2EE) multi-level structure as the overall architecture. The mature Microsoft SQL Server 2008 introduced by Microsoft is used as the database platform. Combined with Model View Controller (MVC) design pattern, this system can be used by users without geographical restrictions and system maintenance. In this system, performance logic and business logic are separated, which makes it convenient for the development and maintenance of the system. The system mainly includes six modules: personnel management, organizational management, recruitment management, training management, salary management and system management, which integrates enterprise information and realizes the functions of easy access and easy query of information database. Its interface is simple, easy to understand, and easy to operate, with low investment, low cost, high safety, good performance and easy maintenance, which help to improve the work efficiency and modern management level of enterprises. In the end, the operation performance of the system is tested. The results show that the throughput of the main functional modules in the system is greater than 100 times/s when dealing with the business, and the success rate of event processing is greater than 99%. The average response time of the business end is less than 0.4 s, and the average response time of the terminal side is less than 0.5 s, which all meet the standards. System CPU occupancy rate can be basically controlled below 30%, and memory usage rate is below 30%. In summary, the system designed here has the basic functions but also to ensure good performance, suitable for enterprise personnel management, organizational management, recruitment management, training management and salary management. The design and development of this system aims to provide technical support for the service quality of enterprise human resource management business, to improve the overall efficiency, promote the pace of enterprise strategic development, and enhance the market competitiveness of enterprises.

According to some reasons, such as multifarious, low efficiency status of scientific research management work by artificial way, furthermore, big workload and poor adaptability of requirement change exists in traditional software development method. In this paper, a typical model of scientific research project management process was build based on workflow technology. The business logic and specific function of project management were designed separately, so a unified and orderly management of scientific research project was realized, and flexibility and system adaptability were enhanced too. Rapid development platform technology was chosen in the business system development. This technology affords a develop mode of parameter customization and it could manage intelligence report, data maintenance, Model View Controller (MVC) service control and other parameters. Compared to the traditional programming development mode, a complex and high quality business system can be developed conveniently and fast.

This paper proposed a model editor that can create graphically multiagent models, and a simulator development method using the editor to build multiagent simulators. Development and management of the models became very easy. In addition, reusability of the models also became very high, and simulator platforms could be changed flexibly. The proposed method was applied to some multiagent simulators and the results show that our method is effective in developing multiagent models and simulators. As future problems, we must improve the model diagrams to increase automatic code generation rates, and prepare other templates for various frameworks.

Real-time monitoring microblog data can find sensitive information in time and provide help for public sentiment management and control. However, it needs processing large-scale data stream. MapReduce is a framework of processing large-scale data in batch mode, its purpose is to increase throughput, but its real-time performance is limited. Aiming at the real-time performance limitation of MapReduce, RT-SSP Real-Time Staged Stream Processing, a hybrid staged real-time stream processing scheme both for batch and real-time processing was proposed. By this method large-scale high-speed data stream is locally processed in stages, the communication cost is reduced by storing intermediate results to local node, and key technologies such as cache optimization are used to realize high concurrent read and write. Experiments show that RT-SSP scheme can improve the real-time performance of processing large-scale microblog data stream and achieve speed-up ratio of about 2.3.

This paper presents a formal development approach for designing interactive applications using a correct-by-construction approach. In this work, we propose a refinement strategy using model-view-controller (MVC) to structure and design Event-B formal models of the interactive application. The proposed MVC-based refinement strategy facilitates the development of an abstract model and a series of refined models by introducing the possible modes, controller’s behaviour and visual components of the interactive application while preserving the required interaction-related safety properties. To demonstrate the effectiveness, scalability, reliability and feasibility of our approach, we use a small example (from automotive domain) and real-life industrial case studies (from aviation). The entire development is realized in Event-B and the associated Rodin tool is used to analyse and verify the correctness of the formalized model. Finally, the developed Event-B models are used to generate source code using EB2ALL tool for going from the specification to the implementation of the interactive application.

Due to the rising demand for large-scale data processing, there is a growing interest in both batch processing, where large volumes of data are processed offline, and stream processing, where large quantities of streaming data are processed online. The dichotomy between these vastly different computing paradigms has led to the development of substantially different methodologies and systems. As there is an increasing number of applications requiring stream and batch processing, there is a need to bridge this gap and offer support for both paradigms. We introduce a new direction for the unification of stream and batch processing, which, contrary to other proposed approaches, uses a stream processing platform as its foundation and supports batch processing on top. Our proof-of-concept implementation of such a middleware layer, called Cyclone, offers the widely popular MapReduce programming model and translates MapReduce jobs for execution on the underlying streaming platform. Cyclone not only achieves a tight integration of batch and stream processing, our evaluation further shows significant performance gains, in particular for sequential and iterative jobs, which naturally arise in many applications.

The rapid development of information technology has provided significant opportunities to improve the efficiency of academic administration in schools. One of the common problems faced by educational institutions is the manual process of subject scheduling, which is time-consuming and prone to schedule conflicts among teachers, classes, and learning time. This problem is also experienced by SMPK Flos Carmeli, where the preparation of subject schedules has not yet been supported by an integrated computerized system. This study aims to design and develop a web-based subject scheduling application at SMPK Flos Carmeli using the Model–View–Controller (MVC) architecture. The research method employed is Research and Development (R&D) with the Waterfall software development model, which includes the stages of requirements analysis, system design, and application implementation. Data were collected through interviews, observations, and literature review to obtain system requirements that align with the school’s conditions. The application was developed using native PHP with the implementation of the MVC pattern to produce a structured, maintainable, and flexible system. The results show that the developed application is able to support the subject scheduling process in a faster, more accurate, and well-organized manner. The system provides features for managing teacher data, class data, time slots, schedule arrangement, and schedule printing, thereby minimizing schedule conflicts and improving the efficiency of school administrative work. Therefore, this subject scheduling application is expected to support the digitalization of academic administration and enhance the effectiveness of the teaching and learning process at SMPK Flos Carmeli.

In modern complex enterprise applications re-usability and interoperability of software components are of vital importance due to the increasing heterogeneous development platforms and variety of end user devices in which computational services need to be exposed. The need of code solutions re-usability led to the development of Design Patterns, which are means to encapsulate proven solutions to recurrent problems and they provide developers with a common language to abstract the logic encrypted under source code implementation structures. In this article we focus on the Model-View-Controller (MVC) design pattern. Although it represented a step forward for components re-usability, the model and view are still coupled compromising the business logic and introducing a degree of complexity for the applications development. We discuss two main variations of the MVC pattern that are aiming to complete decoupling of Model from View, as well as platforms supporting the development of MVC based applications. Our research is based on the original Virtual-MVC design pattern, in which we model the controller as middleware to achieve full decoupling of the model from view. Our main contribution is to demonstrate the development process of re-usable components in the framework of the V-MVC pattern, through a development platform that supports Virtual-MVC based applications.KeywordsDesign PatternsModel-View-ControllerService Oriented ArchitectureWeb ServicesE-Learning

There is a lot of routine work in any organization, including in recruitment agencies. Effective management organization and automation of activities of employees of recruiting agencies is not an easy task. The system should automate the routine actions of workers of recruiting agencies and be convenient for their clients. This paper proposes an approach to automating the selection of necessary medical staff. Not all information systems used by recruiting agencies can compare candidates and generate results that include several of the best candidates. Based on the analysis of the subject area, groups of parameters that significantly affect the choice of medical personnel were determined. The proposed approach is to analyze the request from the client, and then in the system find requests of other clients similar to it in terms of parameters, for which a candidate has already been found. The next step is to take the profiles of healthcare professionals that have been suggested for these requests (they act as benchmarks) to further compare them with existing candidates. Each employee profile parameter has its own similarity function. Available candidates will receive scores and will be ranked. We also additionally adjust the assessment by comparing candidates with the current request. Software was developed to automate the selection of medical personnel. For its implementation, a three-level client-server architecture is proposed. MVC (Model View Controller) architecture was chosen for the server part. The Single Page Application architectural template is used for the client part. The server part is divided into three layers, which further demarcate and structure the responsibilities of the system components. .NET technologies are used to implement business logic. SQL Server is used for the server and database provider. The use of the software implementation of the developed system demonstrated quite good results. The average time for selecting the 10 best candidates out of 500 is 0.4 seconds, and the processing of only 1 resume by a person takes several minutes.
