When we are talking about recent challenges about storing Big Data in appropriate database, it’s tough to answer questions like: Which is better: SQL or No-SQL. Should we use RDS or NO RDS? Particularly, in our case: PostgreSQL or MongoDB? My problems is all about storing bank statements into the database, and after that, could run simple, but natural, necessary, queries for solving given business problems. After some structural and time complexity analysis, I decided relational model for storing my bank statements wit no doubt. Postgres outperforms MongoDB with the given task.
