 == Twin articles == 

 I noticed you have created two articles with identical content, Data Lineage, and Data Lineage for Big Data Systems. So as to not cause confusion, can you please indicate which article you wish to be deleted, since deletions of one (or both) article(s) have been rejected. If you do not comment, I will put a speedy deletion tag on the smaller article, which has less content than the other.   ⋠⋡ "
