Codasyl vs. CODASYL
From the lede:
the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language
I find that hard to believe given the NoSQL trend/hype of the last decade. CouchDB, MongoDB, Apache Cassandra, etc., all qualify as DBMSs as defined in this article, but don't support the relational model or SQL.
More generally, the lede seems rather slanted towards SQL. Does anyone have a reliable source that quantifies the popularity of SQL/NoSQL? On NoSQL, I found this web page that purports to show that at least in terms of number of major systems, RDBMSs are now in the minority. QVVERTYVS (hm?) 18:53, 23 June 2015 (UTC)
- But, has an invividual NoSQL system actually made it into the ranks of "the most puplar databases systems"? —SamB (talk) 18:38, 3 July 2015 (UTC)
- The article you cite says nothing of the kind. It says that its figures "show that relational systems currently totally dominate the database market, but NoSQL systems have a strong upcoming trend" Its figures show 6 of the top 7 being relational, together accounting for about 95% of the market.

(see Implementation section below)
- That section was removed 2½ years ago; it was a summary of the separate article Database management system that was merged into this article. I've removed the references as the treatment of DBMSs no longer has any separate section or article. QVVERTYVS (hm?) 12:22, 26 November 2015 (UTC)
How is it possible that the word databank is not even mentioned in this article? The difference between the two or the lack of one is badly explained in that article. --Espoo (talk) 05:56, 4 August 2016 (UTC)
