A Word on Handing In Assignments
-
All hand-ins consist of ONE, repeat ONE compressed
zip/jar/tgz-archive.
-
An archive consists of one or more text files
and/or code files.
-
Text processed files must be
pdf-files.
-
Code files must be have
their native filename extension, eg.
x.java, y.html, etc.
-
Put your academy login-id into the filename, and
an "_7" to number the file individually,
eg:
EAANILA1_7.zip
-
Put the token dbxml somewhere in the subject,
eg:
Assignments dbxml
-
Mail it to
nml@acm.org
Given the boys and girls names tables you have to do the following:
-
Select the 5 most common boys names.
-
Select the 5 least common girls names.
-
Select a union of the 5 most common
boys name and the 5 most common girls names.
-
Select a union all of the 5 least common
boys name and the 5 most common girls names.
-
Find the unisex names ie the names that are boys names
and also girls names. I want at least 5 different ways
of doing it ;-)
-
Find all the boys names that are not also girls names.
Give me two solutions. Try to argue the plausibility of
your results.
