Deletion of ERROL

Comment: Preceding discussion pretty much nails it.  To establish notability under , you need reliable independent secondary sources.  There aren't any.  Notability here means other people not connected with the product thought it was worth writing about, not just the author thinks it's pretty cool and wrote a lot about it

Comment: This article gives  coverage of one specific entity-relationship language. What would be more appropriate would be a Wikipedia article on such languages more generally, giving appropriate coverage to the http://scholar.google.co.il/scholar?hl=en&q=%22entity+relationship%22+intitle%3Alanguage&btnG=Search&as_sdt=0%2C5&as_ylo=&as_vis=0 several other ones that are more notable than ERROL. As for the 29 hits in an early comment from ERfan (whose name does not exactly convey an image of neutrality): most of them appear to be primarily about other e-r languages and tools and only cite ERROL as part of their competition, rather than having nontrivial coverage of ERROL specifically. For instance, the first one, "A graphical data manipulation language", does not even mention ERROL in the main text of the paper, only includes a reference to it at the end in a collection of "nongraphical ER languages". The second one, on SQL/EER, only has one sentence citing ERROL and four other languages. The third one (skipping the ones by the ERROL authors themselves) is the one on QBD*, again includes it in passing as one of five citations for the phrase "fourth generation languages". So I'm also not convinced that there's really adequate depth of third-party coverage

Comment: Borderline notable academic work. Does not pass  ("topic has received significant coverage in reliable sources that are independent of the subject"). A complete lack of inline references, peacock language and excessive zealotry surrounding these article does not help either
