Data Indexing | Web Scraping Tool | ScrapeStorm

ScrapeStorm is a powerful, no-programming, easy-to-use artificial intelligence web scraping tool.

Introduction

Data indexing is a data structure used to accelerate data retrieval. It improves query efficiency by establishing a mapping relationship between keywords and data storage locations.

Applicable Scene

It is suitable for scenarios where frequent and fast query, sorting or grouping are required in large-scale data storage systems, such as database systems, search engines and data analysis platforms.

Pros: Quickly locate data through index structure, reduce the cost of full table scan, reduce the frequency of disk I/O operations, and improve overall data processing efficiency.

Cons: Indexes require additional storage space, and the index structure must be maintained synchronously when data is updated. Frequent data insertion, update, or deletion operations will cause index reconstruction, affecting system response speed.
