Implementing crosscutting concerns for transactions is difficult, even using Aspect-Oriented Programming Languages (AOPLs) such as AspectJ. Many of these challenges arise because the context of a transaction-related crosscutting concern consists of loosely-coupled abstractions like dynamically-generated identifiers, timestamps, and tentative value sets of distributed resources. Current AOPLs do not provide joinpoints and pointcuts for weaving advice into high-level abstractions or contexts, like transaction contexts. Other challenges stem from the essential complexity in the nature of the data, operations on the data, or the volume of data, and accidental complexity comes from the way that the problem is being solved, even using common transaction frameworks. This dissertation describes an extension to AspectJ, called TransJ, with which developers can implement transaction-related crosscutting concerns in cohesive and loosely-coupled aspects. It also presents a preliminary experiment that provides evidence of improvement in reusability without sacrificing the performance of applications requiring essential transactions. This empirical study is conducted using the extended-quality model for transactional application to define measurements on the transaction software systems. This quality model defines three goals: the first relates to code quality (in terms of its reusability); the second to software performance; and the third concerns software development efficiency. Results from this study show that TransJ can improve the reusability while maintaining performance of TransJ applications requiring transaction for all eight areas addressed by the hypotheses: better encapsulation and separation of concern; loose Coupling, higher-cohesion and less tangling; improving obliviousness; preserving the software efficiency; improving extensibility; and hasten the development process.

One of the main goals of Open-Source Web Server (OSWS) is to abstract away the complexity that can be faced when creating a web application, allowing developers not to worry about needed infrastructure early in the process. Each OSWS is built independently with specific qualities that give it unique structure and possibly impact its out-of-the-box performance. This paper presents a controlled study that examines three OSWSs, evaluating their out-of-the-box performance. Most OSWSs allow configuration that can help extract all of its potential performance. However, applying such configuration might be difficult to new developers, therefore, this study focuses on evaluating the OSWSs performance without applying further configuration. The result of the study shows that Tomcat OSWS is the most ideal WS for our test case, compared to its opponents, as it was able to serve 500 HTTP requests received over 10 and 3 seconds with the smallest average ST and the least LTC.

Tibco OnlineTraining : TIBCO iProcess Suite could be a tested and comprehensive beats per minute suite that allows enterprises to model, automate, and optimize any kind of business method – from routine tasks to mission vital, long processes that involve individuals, info, and applications across structure and geographical boundaries. Suite provides a whole end-to-end method management resolution for all components of the business method life cycle from method modeling through implementation, execution and monitoring, and optimization. Suite is easy enough training that you simply will begin with one division method And powerful enough to scale to many processes across an enterprise. TIBCO was created by team lead James goose of Sun Microsystems .It is completely object aligning program (OOP). TIBCO was written as an alienable language, that does not care, concerning any OS or the hardware of the system. This code designed associate degreed written just the once for associate degree excellent " practical machine " to run on different types of systems, in conjunction with Windows Microsoft pc's, Linux, and operating system computers. Fundamentals of TIBCO came from C++. TIBCO training built with improved ideas of c++, to provide a linguistic communication that was powerful and clear-cut to use. TIBCO is in 2 types, core TIBCO and advanced TIBCO. Core TIBCO is also a whole application and advanced TIBCO suggests that applications will run on servers. is the best and excellent Tibco Online Training Institute In Hyderabad, India.

This thesis concerns the topic of mixed, digitally augmented reality. It is increasingly difficult for one to navigate the field of augmented reality and wearable computing terms and technologies where many established scientific definitions are being clouded by a fuzzy pseudo taxonomy of media and marketing labels. We set ourselves to elaborate on currently available platforms for augmented reality while keeping tight bonds to definitions established by Ronald Azuma, Paul Milgram, Steve Mann and others. Furthermore, we offer motivations for bringing augmented reality into user space, thus moving from the realm of technical demonstrations to a real world application prototype. INSANIA, an Android application written in C/C++ and Java, leveraging Qualcomm Vuforia SDK and OpenGL ES 2.0, explores difficulties in an ordinary user interaction with audio-visually augmented reality. PinBoy, a former Java Micro Edition MIDlet with a simple Python backend offering audio augmented reality was brought forward to an Android implementation with a Java EE backend comprising of EJB 3 and MyBatis, taking advantage of Google Cloud Messaging, Cloud Connection Server (XMPP) and OpenShift deployed WildFly application server.
