-
- SGML is a description language, while SQL is a query language. There's
- nothing to keep you from applying SQL to an SGML document treated as a
- relational data base. SGML certainly has the power to describe it,
- although you probably would build a more efficient system for your
- access needs. SGML has been used as the interchange format between
- dissimilar RDBMS's with great success, for instance.
-
- Tables pose great challenges in all descriptive languages, since people
- tend to be overly interested in table layout, and understanding how to
- separate the information in a table from its layout is not complete.
-
- Jim McCauley's definition is right on track, but tables get very hairy
- once you go beyond the clean, two-dimensional tables, and into three- or
- four-dimensional information structures mapped into two dimensions in a
- table with subheadings, categories, footnotes and cross-references. We
- know a lot about how these beasts should be formatted, but the "database
- for the eyes" approach could perhaps point us in the right direction for
- understanding the information structures involved that are now largely
- implicit in the table designer's mind.
