Introduction to data tables

The translations database contains many data tables. Each table has a
purpose and contains a specified type of data. When you enter datafill, you
enter specified data in a table. The following section describes the structure
of data tables.
Data associated with hardware and software systems of the Digital Multiplex
System (DMS) switch are stored in tables.
A table contains rows and columns. A row is a tuple. Columns represent
fields in a tuple. Refer to the following figure for examples of a table,
subtable and sub-subtable.
Each field has a different field name that contains a maximum of eight
characters. The field name is a prompt for data input.
A field is a single-element field or a multiple-element field with subfields.
A field or subfield contains data in the form of numbers or alphanumeric
strings.

Tuple properties

A different key identifies each tuple.
A key contains the first field. For most tables, the key forms one field. In
other tables, the key requires a minimum of one field of data to make the key
different. In this occurrence, the first field and one or more following fields
in the tuple form the key.
The key or the table editor (TE) cursor reference tuples. The cursor is an
internal pointer to a tuple of a table. Use TE commands like POSITION,
LIST, BOTTOM, and TOP to move the cursor. Refer to the Table editor
commands table in this section for a description of TE commands.
The tuple the cursor points to is the current tuple.
