# CD-ROM Structure

This CD-ROM is a hybrid disc in ISO 9660 format. The hybrid structure allows PC, Macintosh, and UNIX users to share the same directory structure and access common files.

The contents page provides links for chapters 3 through 12 (chapters 1, 2, and 13 do not have ancillary content on this CDROM). Note that some of the links point to the same page. For example, both chapter 3 and Chapter 4 link to datatype/index.htm, which provides information on instants, intervals, and periods. Similarly, Chapters 5-7 all point to a Web page on valid-time state tables.

Each chapter contains an index.htm file. This file contains generic information about each chapter and links to the DBMS-specific index.htm file.

Each DBMS implementation in each chapter has ONE .htm file containing all DBMS-specific information for that chapter. As these were developed in parallel with the writing of the book, the numbering of the code fragments on the CD-ROM may not always correspond to the numbering of the code fragments in the book itself.

This DBMS-Specific HTML file is divided into three sections:

Contents | Briefly lists the major headings in the page. Usually fits in one page.
Outline | Complete hierarchy of headings in the HTML page. This is useful for people who may not know what exactly they are looking for.
Body | Contains the DBMS-specific data, results and links for that chapter. Note that each major Chapter/Heading has links back to the outline, contents, and top of page.

The Language Directions page differs from the other chapter pages, in that rather than referencing code fragments, it references white papers, technical reports and proposals (SQL/Temporal, TSQL2, TimeCenter, and KPN links), prototypes you can transfer to your hard disk and run (TimeDB1 and TimeDB2 links), and information and web pages on systems (Tiger and Synchrony links).
