Customizing the database layout

5.2.2 The tbl file

The description file that is called using the -toption, the so-called tbl file, contains the customizing functions:

–name mapping of database tables and definition of the concrete storage space required by tables (section 1 on page 35),

–fragmentation of a database table (section 2 on page 37),

–name mapping of views (section 3 on page 37),

–versioning of the database (section 4 on page 38) and

–access privileges for tables and views (section 5 on page 38).

The specification of this file, and of all entries in it, is optional.

The structure of the tbl files follows the general structure of the intermediate format files (see the chapter entitled Tools in the Reference Manuals [14]). The following line types are supported:

#for identifying a comment line

# comment text

tfor identifying a definition line for the mapping of database table names or for defin- ing the concrete storage space required by tables

fr for identifying a definition line for fragmenting a database table

vfor identifying the version control

sfor identifying a definition line for access privileges

vw for identifying a definition line for the mapping of database view names

The meaning of the individual lines as well as the necessary columns are now described for each customizing function.

1.Name mapping of database tables and definition of the concrete storage space required by tables

A table line contains the following fields:

t ident name resource firstExtent nextExtent Only one definition line of this type is permitted per class. Note that all “” separators must be set.

ident Name of the class in the specialist model.
