What is use of compress in terdata?Explain?..

Answer / oceanblue

Part of the answer by Sat!sh is correct.

However, we can store only one value per column and not 3
(air, sea, road). The compressed value is stored in column
header and is to be used as default of that column unless a
value is present.

e.g.
Dept of Taxes in Washington has a database that tracks all
people working in Washington. Around 99.9% of the tax payers
would have Washington as their state code on their address.
Instead of storing “Washington” in millions of records the
compress will store the value “Washington” in the table
header. Now, a value can be assumed in a row as a default
unless another value exists inside the column.
