Need for Data Structure

 As applications are getting complex and data rich, there are three common problems that applications

face now-a-days.

 Data Search − Consider an inventory of 1 million(10⁶) items of a store. If the application is to

search an item, it has to search an item in 1 million(10⁶ ) items every time slowing down the

search. As data grows, search will become slower.

 Processor speed − Processor speed although being very high, falls limited if the data grows to

billion records.

 Multiple requests − As thousands of users can search data simultaneously on a web server, even

the fast server fails while searching the data.

To solve the above-mentioned problems, data structures come to rescue. Data can be organized in a

data structure in such a way that all items may not be required to be searched, and the required data

can be searched almost instantly.
