For Homework 2, please submit source code of all queries in three separate files: hw2.ra, hw2.sql, hw2.pl. Also submit three files that contain terminal captures of the execution of these queries. The terminal captures are created as follows:

$ script hw2ra.cap
$ java RA spjdb
RA> query1;
query 1 result
...
RA> query2;
...
RA> exit;
$ CTRL-D
$
At this point the file hw2ra.cap would contain the terminal capture.
Similarly for hw2sql.cap and hw3datalog.cap.

Submission Instructions: Please copy ~raj/.cshrc one more time into your home directory
and logout and re-login. This will enable the handin8710 command. After that you can submit
assignment files as follows:
$ handin8710 2 file1 file2 etc.

Here 2 is the assignment number. For the 3rd assignment it will be 3 and so on. You may
submit any number of files with one command.
