What may be a limitation of WolframAlpha?

Some limitations include:
• it only provides you with one result (answer) for your search (question)

• less variety of sources

• difficult to find specific things such as websites, articles, etc.

• because it is fairly new, it most likely covers less subjects/topics

How is WolframAlpha different?

WolframAlpha is different to the examples of databases listed because it is an answer-engine. It is different to search engines like Google because it provides one answer to the question/search, as opposed to search engines which provide you with a broader range of results. The difference with the rest of the examples is that it can only be accessed online.

examples of databases;

• search engines: Google, Yahoo, Bing
• phone books
• newspaper
• contacts (on the phone)
• library

What is a database?

A database is a collection of related data, organised for convenient access. It is organised in a way that it is easier to find and select a desired piece of data. It is somewhat of an electronic filing system.

In order to access a database, a Database Management System (DBMS) is required. This enables you to select, organise and edit/enter data in the database.
