When you traverse the link, this object is dynamically extracted from the Sybase database there and formatted as html. As you can see, the a1 entry contains many links to other objects.
Genera provides very simple mechanisms for creating such cross-database links.
Sybase is a relational DBMS, and does not have an inherent notion of an object . In order to know how to format objects, sybfmt needs to have them defined. This is done using schemas written in a simple notation. Schema files mainly state what the fields to be displayed are, what type of data they contain, and what Sybase table column they are stored in, plus additional annotations to invoke various Genera special features. Here is a sample schema file.
