摘要：Public sector such as Govt. University composed of many physical as well logical threads, which are very beneficial for public to provide services. Over times due to repeated modification of software modules, the structure of the system deteriorates and it become very complex to understand for further modification whenever requirement need to provide services to public, because it is universal truth after specific time period there is need of modification to fulfill the requirement for public. And if we repeat to modify the software module, then it is very complicated just like noodles in chowmin plate and program structure is twisted and tangled. Due to this program structure greatly decrease the scalability, reliability, efficiency, robustness and increased the complexity of software module. And it also increased the maintenance cost of software module, therefore repeated modification is not a good choice. Reengineering is good choice for this. Therefore, in this paper we will introduced a new methodology that is known as pattern based reengineer methodology, that is not only focus on only logical thread, but also focus on physical entities - reduce overall complexity. It is proved that the transformation does not alter the semantic of restructured program.
