How effective was the tutorial, who might find the tutorial useful, and any other aspect of the tutorial that you think a reader might find useful
After going through the tutorial, I have found it interesting informative, and comprehensive. The approach used by the writer is straightforward and builds on issues slowly but sue. Beginners need such tutorials as they can simply explain database management and capture the attention of users. To test understanding after every segment the tutorial is offering an example followed by a task that users can use to test their understanding of the matter taught in the previous lesson. The writers of the tutorial seem to be fully conversant with the area and are willing to share their skills and experience with users.
The command languages that are used in the tutorial are similar to the command language that users are likely to get in real situations case; this helps in creating the right picture for users right from the start.
When tutoring, the system assumes that the user is ignorant about database management thus it starts from the simplest elements of database management and retrieval of information then builds on the understanding to offer the training. For users who have used tutorials again, the system offers a good refresher to sharpen one’s skills and expertise.
