This paper analyses five basic features of product data management and combines them with real industrial examples. Then, an object oriented product data management model is presented. To carry out the model, the paper presents the architecture of the Cax information management and integration system (Cax IMIS), and focuses on its core technology, implementation of an object management framework, and discusses the process of realizing the inherent attributes, relations, and messages between objects using the object dictionary and storing detail information about the persistent objects in relation database management system (RDBMS). The method provides an effective object management framework for Cax IMIS.展开更多

This paper is based on the examination of project management achievement. A system analysis of accomplishment examination has been made from the implication, content, style, method, aim, principle, procedure, kind to restriction, psychology effect of accomplishment examination. The purpose of aforementioned all is for the establishment of whole system and thought in the study, foundation and implement of project accomplishment assessment.展开更多

Server applications usually run for years and spawn many threads, so they create and discard thousands of objects. Therefore, efficient garbage collection is especially important for those applications. This paper presents a class-based garbage collector for object-oriented programming environments that classifies objects by their types to achieve better gradualness. Grouping objects of the same type into a group, with a limited type-lock, a mutator cache and the lease protocol will reduce memory fragmentation, which is especially important for the efficiency of long-running server applications. This class-based collector partitions the heap space by type, which provides better concurrency than the traditional mark-sweep collector, and its reusable garbaged object pool also reduces the object allocation overhead. This paper also discusses the implementation details, such as the mutator cache and the lease protocol, and techniques to achieve better accuracy.展开更多
