Body
You can try this. file a.awk: <pre><code>BEGIN { # read list of items while ( ( getline < "dummy_list" ) > 0 ) { items[$1] = 0 } } { # calculate ammountof uniqur ids key = $3 SUBSEP $6 if ( ! ( key in ids ) && ( $3 in items ) ) { unique_ids[$3] += 1 } # calculate ammount of duplication ids [$3,$6] += 1 # calculate range parameters range1 [$3,$6] += $5 - $4 range2 [$3,$6] += $7 } END { for ( item in items ) { print "--- item = " item " ---\n" for ( key in ids ) { split ( key, s, SUBSEP ); if ( s[1] != item ) continue; range = range2[key] * 100 / range1[key] average[item] += float ( ids[key] ) / unique_ids[item]; print "id = " s[2] "\tammount of dup = " ids[key] " range = " int ( range ) } print "\naverage = " average[item] "\n" } } </code></pre> run: <code>awk -f a.awk dummy_table</code> output: <pre><code>--- item = AAAA --- id = "ID-983" ammount of dup = 1 range = 266 id = "ID-923" ammount of dup = 2 range = 130 id = "ID-482" ammount of dup = 4 range = 110 average = 2.33333 --- item = AAAAA --- id = "ID-916" ammount of dup = 1 range = 390 average = 1 --- item = AAA --- id = "ID-999" ammount of dup = 2 range = 288 id = "ID-482" ammount of dup = 1 range = 240 id = "ID-492" ammount of dup = 2 range = 242 average = 1.66667 </code></pre> There is one moment - I can't understand how you got 225 for "ID-482" and item AAA in question #3. <pre><code>RANGE2 * 100 / RANGE1 = 36 * 100 / ( 58 - 43 ) = 240. </code></pre> Are you sure, that your example on question #3 is correct?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
