The need to identify source code that exhibits particular characteristics is essential to program comprehension. In this paper we introduce ARABICA, a tool for querying Java code using UML class and sequence diagrams. Our use of UML diagrams avoids the need for developers to familiarize themselves with yet another language. In contrast to tools that rely on dedicated query languages, ARABICA encodes querying semantics in a dedicated, minimal UML profile. Stereotyped class and sequence diagrams, characterizing structural and behavioral properties respectively, are translated into logic program queries. Using examples from the JHotDraw framework, we illustrate the utility of ARABICA in validating design invariants, finding design pattern implementations and exploring extension points. We present a pre/post-test quasi experiment as a preliminary assessment of our approach.

Multi-tenant systems represent a class of software-as-a-service (SaaS) applications in which several groups of users, i.e. the tenants, share the same resources. This resource sharing results in multiple business organizations using the same base application, yet, requiring specific adaptations or extensions for their specific business models. Each configuration must be tended to during evolution of a multi-tenant system, because the existing application is mended, or because new tenants request additional features. In order to facilitate the understanding of multi-tenant systems, we propose to use a runtime topology augmented with user and version information, to help understand usage patterns exhibited by tenants of the different components in the system.We introduce Serviz, our implementation of the augmented runtime topology, and evaluate it through a field user study to see to which extent Serviz aids in the analysis and understanding of a multi-tenant system.

Abstract-Green Ajax as a new approach in the web development has an aim to create interactive communication between server and client but avoiding the useless redundant requests. Some researches have been conducted to prove the benefit of Green Ajax, compared to Classic Ajax. The results of experiment show that the performance of Green Ajax is better than Classic Ajax in almost of all conditions. These results strengthen the conclusion that Green Ajax is a good approach in the web-based application development.However, some further researches have to be conducted in different environments to prove that the conclusion is also valid for a wider variety of conditions. One of those conditions is the wireless Local Area Network which is now very commonly available in schools, hotels, offices and business centers. Thus, the implementation of Green Ajax for the applications that support business, not just an experiment, can be realized immediately by using Randomized Cue Applications. This paper will focus on the analysis of Green Ajax performance on the wireless Local Area Network. The program discussed will demonstrate the ability of Green Ajax in providing a good interaction between users and the web server. The results of the experiment confirm that the Green Ajax is suitable for the applications on the wireless Local Area Network. Network traffic reduction is obtained as the final result in the use of Green Ajax.Index Terms-Green Ajax, network traffic, web-based application, wireless LAN. I. INTRODUCTIONGreen Ajax is an enhancement of Classic Ajax which has been recognized in the web application. Inheriting from the origin, Green Ajax also has the ability to decrease the bandwidth consumption by delivering data only in the specific part of web page [8]. The user interfaces will display any information without any interruption on screen because the communication between web application and server is done in the background.The improvement is located in the ability of web application to receive notification from the server whenever an update or a change of data occurs. When the application receives the server's cue, the application will then send out a request [7]. The applications will display the latest information without any involvement from the user. This method reduces required bandwidth below than necessary for data updating.In the previous experiments done in the wired Local Area Network, Green Ajax has been proven as a suitable approach for web-based application in variety conditions. When the server updates the data in unpredictable time, Green Ajax applications are always able to be a better approach in displaying the latest data. Green Ajax sends fewer requests to the server compared to Classic Ajax. The less bandwidth consumption of Green Ajax reduces the network traffic [7].Furthermore, Green Ajax is still able to display the latest data using smaller amount of requests than Classic Ajax even though the server updates the data at the scheduled time and Classic Ajax uses the same interval time of data up...
