Table extension functionality allows

for inheriting fields from a parent table.

Tables are extended by administrators and developers

while creating tables

.

Table extension is used for a set of records

to share information with each other.

In the use case listed below, the Task table has multiple extensions:

An extended table

is called a child table, and

the original table

is called a parent table. A child table in its turn can

also be extended, i.e., a child table can have child tables itself.

Table extending causes the following:

• Cross-table linking between

• the new table

• and the extending one

• System fields are created in the new table (like the sys_id field)

• .
