We can also announce a contest for the customers to buy the product and win a chance to get himself broadcasted for the product advertisement. We can ask them to send in their photo along with the contest application form which they get alongwith the product they buy. So we don’t have to pay them as we would otherwise have to pay to a celebrity.

These days channel members are being accepted by companies as their partners. The intermediaries are even being asked to integrate their business with the companies which results in lesser costs, greater efficiency and improved customer service.

Bitmap indexes make use of bit arrays (bitmaps) to answer queries by performing bitwise logical operations.

Bitmap indexes are useful in the data warehousing applications.

Bitmap indexes have a significant space and performance advantage over other structures for such data.

Tables that have less number of insert or update operations can be good candidates.

The advantages of Bitmap indexes are:

   - They have a highly compressed structure, making them fast to read.

   - Their structure makes it possible for the system to combine multiple indexes together so that they can      access the underlying table faster.

The Disadvantage of Bitmap indexes is:

  - The overhead on maintaining them is enormous.
