An Event Monitor and Response Framework Based on the WSLogA Architecture

Web services provide organizations with a powerful infrastructure by which information and products may be distributed, but the task of supporting Web service systems can be difficult due to the complex nature of environment configuration and operation. Tools are needed to monitor and analyze such Enterprise environments so that appropriate engineering, quality control, or business activities can be pursued. This investigation resulted in the development of a software development kit, the WSLogA Framework, which is inspired by the vision of Cruz et al. (2003, 2004). The WSLogA Framework provides distributed Enterprise systems with a platform for comprehensive information capture and environment management. Five component groups are intended for employment to enable integrated workflows addressing monitoring and response activities, but these components may also be used individually to facilitate the phased integration of the WSLogA Framework into existing environments. The WSLogA Framework\u27s design is portable across technology platforms (e.g., Java and .NET) and a variety of technologies may be substituted for the provided implementations to address unique system architectures. The WSLogA Framework supersedes existing logging and monitoring solutions in terms of both capability and intent. Applications based on the WSLogA Framework have an internal, real-time view of their operation and may adjust their environment based on the information provided by events related to their or system activities. The WSLogA Framework is intended as a software development kit around which system functionality may be organized and implemented, which makes the WSLogA Framework an architectural peer or complement to traditional application frameworks such as Spring\u27s Web module. WSLogA Framework based systems should be envisioned as information appliance elements rather than traditionally scoped applications or services

Automated Text Translation

The paper analyzed the problem of accessibility of content in other languages, it was found that many content may not be translated into the native language of users who want to access it, but at the same time there are many who want to help other users with this problem. The solution is a special information system that allows you to easily register and create your own translation, in which other users can participate, or join another already created one and help. As a result, the interested user can easily download the translation result and use it at his own discretion. The analysis of business processes for the creation and translation of the text was carried out. Based on this analysis, requirements for a future solution were developed. Business requirements were also identified. Among other things, a system use case model was developed and use case specifications were described. Lists with functional and non-functional requirements have also been developed. The functional model of the system was shown - algorithms: authorization, registration, password recovery, creating a new translation, generating a file with a new translation, generating a list of translations, managing users, viewing a translation, editing a translation text, checking the correctness of a translation, and moderating translations. A class diagram was developed, where you can see the main entities of the system and their relationships. A sequence diagram was also developed. The architecture of the information system was described. The system was implemented using the React.JS library and the Spring framework. The main processes of the system users were also described

Web Based Candidate Assessment System

Devplex Technologies Limited is a privately owned company based in Galway Ireland. They have been operating for over two years and currently undertake contract projects for the travel and financial industries. The projects are varied and a wide range of skills are necessary. Devplex Technologies are currently undergoing expansion and intend to hire a number of new employees with varying levels of experience. Devplex Technologies also employ a high number of contractors, with varying skills and contract periods range from one month to twenty four months. The current technical leaders are all very busy with project work. The human resource manager actively advertises positions on both the internet and local newspapers which results in a large number of responses. It is difficult to sort through all the applicants as a high level of technical knowledge is required to vet them. When the human resource (HR) manager selects a number of potential candidates from the vetted curriculum vitas, phone interviews are conducted. The HR manger pools questions which have been submitted from employees who have experience in the relevant technologies. The HR manager has to decide if the candidate\u27s answers are satisfactory for the questions. The most successful candidates are then requested to attend a formal interview. Once a candidate presents for interview they are requested to take a short 10 minute written exam where they are asked to answer five questions relevant to the position they are applying for. Regardless of the outcome of the exam the candidate then proceeds to a formal interview where two or more employees from Devplex Technology interview the candidate and take note of their findings. Once the candidate has left the interview, the HR manager and interviewers meet to discuss the exam and interview and decide if the candidate should be brought for a second interview. If the candidate\u27s second interview is successful the candidate is hired. Devplex Technology interviews a high number of unsuccessful candidates resulting in wasted time and effort. Sometimes employees who are not technically strong enough can be erroneously hired. Devplex Technology wishes to reduce this workload and hire more suitable people by implementing an enterprise based candidate assessment system. The system should allow the remote assessment of potential candidates. It should also allow the HR manager to easily retrieve questions and answers on a selected topic. The system should test the candidates only on subjects which apply to the role they are hired for, the questions should progressively get harder as the candidate gets more questions correct, this will allow for a truly strong candidate achieve the highest score. The overall aim of the system is to reduce workload and help find the best possible candidate for Devplex Technologies

Sales Management Portal

Sales Management Portal is a client information tracking portal. Which client’s info contains contacts and activities, opportunities and proposals, and eventually projects. This portal has ability to add clients and search clients based on the name and prospects and can update information of contacts and activities, opportunities and proposals to the respective client. This portal has ability to display announcements message on manager\u27s screen. This portal should have a responsive design so it will adjust to diverse resolutions, making it easy for users to navigate the portal on their own devices. There are not any existing systems for client side. So all the work are handle manually and have to be noted down in some register and also taking care of that documentation. They are arranged meeting by call and if any update occurred then again the client and update meeting schedule. its wasting time and money as well and also the disturb the valuable clients

Combined PIM-PSM

The Model Driven Architecture (MDA) defines an alternative approach to software development. It allows to separate the system functionality specification from its implementation on any specific technology platform. Following the MDA approach, the first step of a software development project is the creation of a Platform Independent Model (PIM). Such PIM can then be mapped to one or more Platform Specific Models (PSMs). Keeping a PIM and its PSMs separate has many advantages, but it also leads to some problems. One of them is the synchronization of several models. Whenever a PIM is updated, all corresponding PSMs must also be updated to reflect the changes. A solution could be to combine a PIM and all its PSM in one and the same model. How this can be done is the main question of this thesis

Abstraction over non-local object information in aspect-oriented programming using path expression pointcuts

Aspect-oriented software development (AOSD) consists of a number of technologies that promise a better level of modularization of concerns that cannot be separated in individual modules by using conventional techniques. Aspect-oriented programming (AOP) is one of these technologies. It allows the modularization at the level of software application code. It provides programmers with means to quantify over specific points in the base application code, called join points, at which the crosscutting concern code must be triggered. The quantification is achieved by special selection constructs called pointcuts, while the triggered code that is responsible for adapting the selected join point is provided by special construct called advice. The selection and adaptation mechanisms in aspect-oriented programming depend heavily on the distinguishing properties of the join points. These properties can either be derived from the local execution context at the join point or they are considered to be non-local to the join point. Aspect-oriented systems provide a plenty of pointcut constructs that support accessing the local join point properties, while they rarely support the non-local properties. A large research effort has been achieved to extend current aspectoriented systems in order to solve the problem of non-locality. However, none of these proposals support the non-local object relationships. There are many situations where a good abstraction over nonlocal object information is needed, otherwise, the developers will be obliged to provide complex and error-prone workarounds inside advice body that conceptually do not reflect the semantics of join point selection and mix it with the semantics of join point daptation. Such recurrent situations occur when trying to modularize the object persistence concern. Object persistence, the process of storing and retrieving objects to and from the datastore, is a classical example of crosscutting concern. Orthogonal object persistence meets the obliviousness property of AOP: The base code should not be prepared upfront for persistence. This thesis addresses the shortcomings in current aspect-oriented persistence systems. It shows that the reason for such shortcomings is due to the lack of supporting non-local object information by the used aspect-oriented languages. To overcome this problem, this thesis proposes a new extension to the current pointcut languages called path expression pointcuts that operate on object graphs and make relevant object information available to the aspects. As an explicit and complete construct, a formal semantics and type system have provided. Moreover, an implementation of path expression pointcuts is discussed in the thesis along with its usage to show how the aforementioned problems are resolved

Automatic performance optimisation of component-based enterprise systems via redundancy

Component technologies, such as J2EE and .NET have been extensively adopted for building complex enterprise applications. These technologies help address complex functionality and flexibility problems and reduce development and maintenance costs. Nonetheless, current component technologies provide little support for predicting and controlling the emerging performance of software systems that are assembled from distinct components. Static component testing and tuning procedures provide insufficient performance guarantees for components deployed and run in diverse assemblies, under unpredictable workloads and on different platforms. Often, there is no single component implementation or deployment configuration that can yield optimal performance in all possible conditions under which a component may run. Manually optimising and adapting complex applications to changes in their running environment is a costly and error-prone management task. The thesis presents a solution for automatically optimising the performance of component-based enterprise systems. The proposed approach is based on the alternate usage of multiple component variants with equivalent functional characteristics, each one optimized for a different execution environment. A management framework automatically administers the available redundant variants and adapts the system to external changes. The framework uses runtime monitoring data to detect performance anomalies and significant variations in the application's execution environment. It automatically adapts the application so as to use the optimal component configuration under the current running conditions. An automatic clustering mechanism analyses monitoring data and infers information on the components' performance characteristics. System administrators use decision policies to state high-level performance goals and configure system management processes. A framework prototype has been implemented and tested for automatically managing a J2EE application. Obtained results prove the framework's capability to successfully manage a software system without human intervention. The management overhead induced during normal system execution and through management operations indicate the framework's feasibility
