Integrated Data Processing System using MathML as Formula Representation

摘要

The field of statistics aims to study statistical measures to explain collection of objects with census or survey method. In practice, the more objects studied, the more complex the calculations for the statistical measure. Therefore, statisticians need help from computer program to calculate the statistical measure. Statistician not only needs to study statistics, but also needs to learn about programming as well. Most statisticians do not use to write computer programs and choose to use GUI-based applications. However, GUI-based applications give users limited freedom to apply custom formulas. Therefore, this study aims to develop statistical software which enables users whithout or limited knowledge of writing codes to use derived or custom formulas in their original or textbooks-based form within calculations. The application was built using the incremental method, which is one of software development methodology with several iterations. The most important part of application module was built in the initial iteration, followed by next modules, until all application modules have been built. Application can be connected to several data sources such as databases or files provided by users and store formulas that have been made for reuse.
