Chapter 1. Getting Started
Faster and efficient information retrieval is the primary objective of most computer programs. Data structures and algorithms help us in achieving the objective by processing and retrieving data faster. Information retrieval can easily be integrated with algorithms to answer inferential questions from data such as:
- How are sales increasing over time?
- What is customer's arrival distribution over time?
- Out of all the customers who visit between 3:00 and 6:00 PM, how many order Asian versus Chinese?
- Of all the customers visiting, how many are from the same city?
In the efficient processing of the preceding queries, especially in big data scenarios, data structures and algorithms utilized for data retrieval play a significant ...
