下学期有两门data mining 选哪一门好？

下学期统计系开了一个data mining and predictive analysis, 然后cs系开了一个data mining and database programming. 我必须从这两门课里选一门。 统计系的是关于各种数据挖掘模型 Dimensionality Reduction, Regression and Classification, Data Clustering, Text Mining , Parallel Computing, Frequent Pattern Mining, Sequential Pattern Mining，关注于怎么用这些做决策。 cs系的就是 "Theory and practice of information management including PL/SQL; object and object-relational databases; data warehousing; data mining" 问问大家哪门以后会更有用？

学过ML选第二门，学过Database选第一门

读PhD第一门，otherwise第二门
