Reverse Engineering is an approach to extract requirement information application from XML at higher level of abstraction. In the present study XML to UML transformation methods has been explored and discussed along with some other related work in reverse engineering. A brief review of reverse engineering shows that the transformation results of XML to UML are beneficial for developer. However it does not show changes as per the requirements view. Generation of Natural Language specifications from UML class diagrams is also discussed where results were found encouraging and feasible. All related work of reverse engineering of XML and Natural language specification from UML is clear but a lot of work is to be done to solve real world problems satisfactorily. Capability of different reverse engineering tools is also discussed. Automatic code generation using UML to XML schema transformation is reviewed which shows that it can reduce the time and efforts of coding.

The costs of erroneous software can be as of the investment in software development. Yet, the potential to improve software quality and reduce project cost is enormous. Bug tracking and fixing can be an effective means to achieve quality i.e. error free at less cost. A System guides the maintenance activities of software developer's team who earlier, face the problem in fixing bugs. Non-availability of bug in a system in market makes fixing process difficult. Presently Bug fixing is timeconsuming and exacerbates the already high cost of software maintenance which affects scheduled performance. This paper discusses a system that evaluates bugs and assigns priority on the basis of severity to fix them efficiently. .

Measurement is an essential component of software engineering the aim of this paper to identify and analyze complexity of object oriented programming. In this we have applied Cohesion and Coupling metrics on programs of inheritance and interface and evaluate the metrics values. The cohesion and Coupling metrics presented identifies complexity between inheritance and interface programming. In this paper we want to show which concept is good to use and beneficial for software developer. This paper focuseson an empirical evaluation of object oriented metrics in C#. The resulting valueshave been analyzed to provide significant insight about theobject oriented characteristics of reusability programs.

We are living in the era of software and Information technology. Where Reverse engineering has a big role in the up-gradation and maintenance of old software. Precisely if it comes to the reverse engineering of legacy code; so many tools and software are available in the market but still market requirement for reverse engineering of existing codes is unfulfilled. Present paper focus on the various researches published in consecutive years on the same topic. In this study we have covered legacy code and their reverse engineering feasibility as per the cost and time perspective, generation of class diagrams, various problems faced by the different researchers and possible solutions suggested. Conclusion of the study is that we need to do some more experiments to show the class diagram and their relationship and extracting method level dependency while performing reverse engineering of a legacy code by using different language tools and techniques.
