Introduction
Database:
A database is a collection of information stored on a computer. The database is made up of records
– each product record might include a name, a price, a description and a picture. Databases are structured
– they contain the same sorts of information for a collection of similar items. Databases are an essential element of most computer systems, including large websites, e-shops, etc.
Internet

Link
A link, or hyperlink, is a part of a web page that, if clicked with a mouse, opens a different web page. Links are usually shown in blue and underlined on a webpage.
Online

Search
Searching is the process of finding a particular word or topic within a website or on the Internet. When you search, you type in one or more words which describe what you are searching for, and a search engine program looks up a database and shows a list of links to pages that may match what you are looking for. When you search, it is up to you to have some idea of what you are looking for – you have to type in the words to search for. Searches vary in scope – many websites allow you to search the site and all its pages; bigger search engines such as Google allow you to search the whole Internet. Typing CTRL-F lets you search the web page you are looking at.
