if a person stand in row then (off course he looks decent ) but he has to wait much.

In simple words this is the point

but the problem is  that we will have to discuss in tough style.then get marks.

Idea Solution:

Search engine indexing collects, parses, and stores data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, physics, and computer science. An alternate name for the process in the context of search engines designed to find web pages on the Internet is Web indexing. So doing all this operation indexes have to be updated which causes slow manipulation.

Another idea solution

It's because the database server has to do calculations each and every time you insert a new row. Basically, you end up re-indexing the table each time. It doesn't seem like a very expensive operation, and it's not, but when you do that many of them together, you start to see the impact. That's why you usually want to index after you've populated your rows, since it will just be a one-time cost. So, while selecting the column for indexes we should we very care full... its better to create the index on the read only col's.

When data is manipulated, the indexes have to be updated. This slows down data manipulation.

2nd:

Because this operation causes the index to be modified and requires additional updating of each index on that table, 

SQ L has to internally maintain the “pointers” to the inserted rows in the actual data file, Each index potentially adds

 an alternative access path for a query for the optimizer to consider, which increases the compilation time.

Note: don't copy its just for idea.
