数据分析or商业分析应用分析 你弄清楚了吗？

数据分析是指 用适当的统计分析方法对收集来的大量数据进行分析，提取有用信息和形成结论而对数据加以详细研究和概括总结的过程，这一过程也是质量管理体系的支持过程。 在实用中，数据分析可帮助人们作出判断，以便采取适当行动。

数据分析的数学基础在20世纪早期就已确立，但直到计算机的出现才使得实际操作成为可能，并使得数据分析得以推广。可以说，数据分析是数学与计算机科学相结合的产物。

如今世界进入了大数据时代，几乎每个企业都有巨量数据需要分析。因此不论国内外，数据分析专业都非常受到学生的欢迎。就读于该专业将会学习到的课程包括计算机、计算机编程、应用统计学、应用数学、运筹学、优化选择、决策理论等等。
