Answer / siddharth samal

We can also divide up internal table types into three kinds
by their access type:

Standard tables. In a standard table, you can access data
using either the table index or the key. Since the key of a
standard table always has to be non-unique for
compatibility reasons, the system searches the whole table
each time you access it using the key. Consequently, you
should always use the index to access a standard table
whenever possible.

Sorted tables. In a sorted table, the system
automatically stores the entries and inserts new entries
sorted by the table key. The system uses a binary search on
the table when you access it using the key. You can specify
the key of a sorted table as unique. You will often use the
key to access a sorted table, but it is also possible to
use the index. Standard tables and sorted tables are
generically known as index tables.

Hashed tables. You can only access a hashed table using
the key. There are certain conditions under which you can
considerably reduce the access times to large tables by
using a hashed table. The key of a hashed table must always
be unique.
