Web scraping is a computer software technique of extracting information from websites. Such software programs, usually, simulates human exploration of the Web by either implementing low-level Hypertext Transfer Protocol (HTTP), or embedding certain full-fledged web browsers, such as IE and Firefox.
Web scraping is closely related to -
- Web indexing - a universal technique adopted by most search engines which indexes Web content using a bot.
- Web automation - a technique which simulates human Web browsing using computer software.
Web scraping focuses more on the transformation of unstructured Web content, typically in HTML format, into structured data that can be stored and analyzed in a central local database or spreadsheet.
Uses of Web scraping - online price comparison, weather data monitoring, website change detection, Web research, Web content mashup and Web data integration.

Re: Web Scraper
I would suggest the Djuggler web scraper software.
You must understand HTML to use it, but it never has failed me on extracting data from a web site. Even the web page included AJAX or had other complex issues like JavaScript redirects, etc.
