CACTUS is a compact and reliable object storage system based an peer-to-peer architecture with distributed transaction processing capability. The kernel is implemented with the multi-thread mechanisms to provide a high performance multi-transaction environment. All sites, installed with CACTUS, of the networked workstations are on an equal footing. The system can handle local and remote transactions including accessing remote objects or processing remote accesses. In this paper. we give an architectural overview of CACTUS and discuss some implementation issues. It mentions the special contributions such as transient large objects, the coarser lack granularity and its associated protocol. A cost model is developed to demonstrate that the new scheme yields performances which are superior in most common cases and inferior under certain situations.

Software reuse is an effective way to improve software productivity and quality. Software libraries are getting bigger, while most of them, such as those of object-oriented languages, use a simple but somewhat ineffective classification method. These libraries usually provide search aids for novices but experts. They are not flexible enough to serve users at different levels of familiarity with libraries. In this paper, we propose a Software Reuse Framework (SRF) for overcoming the above drawbacks. Based on a built-in hierarchical thesaurus, its classification process may be made semi-automatic. SRF is a domain-independent framework that can be adapted to various libraries and also provides four search levels to serve users with different levels of familiarity with libraries.
