Comments on Oracle XSQL, by M.Thomas

On the bright side, the text is well written, in American English, with a few spelling errors. It provides an introduction to PL/SQL, database design, Oracle Text for Oracle 9i, XML, including XSL, XPath and xsql, which is now considered obsolete(?). Its source code works and could be reused. On the dark side, the book is not an introductory level one, the chapters from the beginning to 14 are more reference like, until the true tutorial building of the web application begins. A javascript or java, introduction is missing, and the paragraphs about XPath are difficult to understand.
All in all, the book can be well used as a reference, provided that several corrections need to be made by the reader, in both its source code and text.
