VDER is a web 3.0 crawling software that uses the Website Parse Template to extract data from websites and outputs them into XML format. It is compatible with various databases such as MS SQL Server, MySQL, Oracle, and Postgres.
The web crawler is a program that automatically traverses the web by downloading the pages and following the links from page to page. This software is designed to achieve the general purpose of downloading any web page that can be accessed through links. The process of downloading and indexing web pages is known as web crawling or spidering.
Web crawlers are widely used by many websites, especially search engines, to provide up-to-date data. The downloaded web pages can be indexed to provide fast searches. However, web crawlers are not limited to indexing web pages. They can also be used to automate maintenance tasks on a website, such as checking links or validating HTML code.
Crawlers can be configured to gather specific types of information from web pages, including harvesting email addresses (usually for spam). A web crawler is a type of bot or software agent that typically starts with a list of URLs to visit. These URLs are called seeds. As the crawler visits these URLs, it identifies all the hyperlinks in the page and adds them to the list of URLs to visit, called the crawl frontier.
The URLs from the frontier are recursively visited according to a set of policies. Overall, the web crawler is a useful tool for indexing and gathering data from web pages, automating website maintenance tasks, and harvesting specific types of information.
