Tentando corrigir um livro
Eſtou tentando já há meſes corrigir o (em outros aſpectos excelente) Oracle Essentials, 3ª edição, da O’Reilly:
Dr. Edgar F Codd first described the relational database concept in an IBM Research Report named Derivability, Redundancy, and Consistency of Relations Stored in Large Data Banks. His 1970 paper was published in Communications of the ACM, and was called A Relational Model of Data for Large Shared Data Banks. The inexistent System R4 Relational name seems to be a mishearing of IBM’s System R subproject of the Future System project, which was thus named in 1974: probably an author overheard someone mentioning it as something like the IBM System R, (where R stands) for Relational. Also, Oracle was not the first relational database. It was the first SQL DBMS: it is neither a database, but a DBMS, nor relational, but based on SQL, which is not relational. Actually the first relational DBMS seems to have been the original University Ingres, before it became the current PostgreSQL.O texto original, errôneo, que tem ſido amplamente copiado e divulgado na Teia (ſegundo o Google), aparentemente porque eſtá diſponível como uma amoſtra copiável em Adobe PDF:
The Evolution of the Relational Database
The relational database concept was described first by Dr. Edgar F. Codd in an IBM research publication entitled “System R4 Relational” appearing in 1970. Initially, it was unclear whether any system based on this concept could achieve commercial success. Nevertheless, Relational Software, Incorporated (RSI) began in 1977 and released Oracle V.2 as the world’s first relational database within a couple of years. By 1985, Oracle could claim more than 1,000 relational database customer sites. By comparison, IBM would not embrace relational technology in a commercial product until the Query Management Facility in 1983.
Hoje deve ſer a terceira vez que envio o comentário acima à editora, através de ſua página de comentários. E até agora, ſe recuſaram a publicar, ſeja o meu comentário ſeja uma verſão ſanitizada dele. Se alguém tiver uma maneira mais política de dizer ißo, ou meſmo parte dißo, por favor, comente… e aguarde a publicação de seus comentários na página de errata ou, pelo menos, na de relatos ainda não confirmados. O meu comentário tem ſido ignorado.
Atualização: Há outros erros no mesmo parágrafo, também enviados à O’Reilly:
The first IBM commercial SQL product was actually 1982’s SQL/DS for DOS/VSE, announced in 1981. 1983 saw also the launch of DB2.
E:
Actually the first IBM relational product was BS12.
