Exercise No. 51: Mails via a Webmail Tool (apa)

This cube stores data about getting mails via a webmail tool.

A user who is of a certain type gets a mail. The mail is delivered by an Internet Service Provider (ISP) and may be encrypted by a certain encryption standard. The mail itself is of a certain type (plain text, html style, etc.). The mail type itself belongs to a certain group. The time dimension consists of month and quarter.

We have five dimensions with the following hierarchical structure:

Table A.E.43.1 - getting mails

Please build the Aggregation Path Array and assume the following end-user requirements:

1) "a roll up by the time dimension starting at weeks for each combination of isp and encryption standard, independent of all other dimensions"

2) "a monthly report on the mail type level independent of all other dimensions"

Select the corresponding cells in the APA and choose the cubes to materialize, then highlight the derivatives of those cubes.
