For lesson 6 we were asked to do research using the invisible web database. The invisible web databases were basically search engines which are not open to the general public like Google, they are more for students from temasek polytechnic.
It wouldn't be good to take the invisible web database as a Google search engine. However using the invisible website would be as ineffective as the subject directories which would provide very little resources using my search query and list out a list of irrelevant sources. Hence it won't be as good as search engine such as Google. Moreover using Google would saves us the trouble of logging in and out unlike private website.
Sharing information on wiki would enhance the spirit of sharing. It has also given me a lot of detailed knowledge on the topic.
