Abstract
Statistical analysis becomes to undertake an important role in the business systems of company, then such systems may build in statistical functions. In this case, it is possible to develop software of statistical functions. But I recommend to apply existing software such as SAS or S-PLUS etc. as considering efficiency of development and reliability of the software. In this paper some systems which incorporate existing statistical software are introduced, the advantages and disadvantages are discussed, and desirable new functions to statistical software are suggested.
