- 6+!1 for mentioning the elephant in the room: the false assumption that one application uses just one DB and that one DB is used by just one appTulains Córdova– Tulains Córdova2016-11-30 10:02:36 +00:00Commented Nov 30, 2016 at 10:02
- 6@TulainsCórdova, I thought the elephant in the room here was Google's payroll system. :)Machado– Machado2016-11-30 12:22:32 +00:00Commented Nov 30, 2016 at 12:22
- 9@Machado This is genius: "I'm willing to bet their payroll system runs on a relational database with lots of constraints."Tulains Córdova– Tulains Córdova2016-11-30 12:27:20 +00:00Commented Nov 30, 2016 at 12:27
- 4It is also handy to have properly constrained databases as your application code is not ACID.Matthew Whited– Matthew Whited2016-11-30 15:46:36 +00:00Commented Nov 30, 2016 at 15:46
- 4Just to emphasise the comment made by @MatthewWhited, it is not possible for applications to enforce some kinds of inter-row/inter-table constraints without performing locking and running extra queries. An RDBMS can do so at much lower cost.David Aldridge– David Aldridge2016-12-06 09:35:25 +00:00Commented Dec 6, 2016 at 9:35

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. design-patterns), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
