23) An e-mail databases is a database that stores a large number of electronic mail messages. It can be viewed as a semi structured database consisting mainly of text data. Discuss the following

 a) How can such an e-mail database be structured so as to facilitate multidimensional search. Such as by sender, by   receiver, by subject, by time, and so on.

b) What can be mined from such an email databases?

c) Suppose you have roughly classified a set of your previous e-mail message as junk, unimportant, normal, or important. Describe how a data mining system may take this as the training set to automatically classify new e-mail messages or unclassified ones.

24) Suppose that a city transportation department would like to perform data analysis on highway traffic for planning of highway construction based on the city traffic data collected at different hours a day.

      a) Design a spatial data warehouse that stores the highway traffic information so that   people can easily see the average and peak time traffic flow by highway, by time of day, and by weekdays, and the traffic situation when a major accident occurs.
