Data environment IBL
The company Internet Big Library (abbr. IBL) was established in the year 2000. The most
important tables of the IBL information system are as follows.
Books (bid, author, title, publisher, year, notes);
Members (mid, name, surname, street, city, country, birthday, phone, notes);
Borrow (rid, bid, mid, date, notes);
TASK 3: Airline transportation
AIRPORT (IDLE, name, city, country)
Relation
Relational schema
I airport
a airplane
p lands
AIRPLANE (IdTL, type, description, manufacturer)
LANDS (#IDLE, #IdTL, dateFrom)
Relation LANDS includes information about where each type of an airplane can land, on what airports and
since when.
Using domain and tuple relational calculus, find:
1. Find all names of the airports, where type B747 airplanes can land.
2. Find all IDLE of airports, on which type B747 or B748 airplanes can land
3. Find all IdLE of airports, which are located in Austria or that type B747 airplane can land on them.
4. Find all IDLE of airports, on which all types of planes can land.
Can you find an example order DFS explores the vertices in the graph included assuming DFS starts at vertex 4. The adjacency lists are in ascending order by the numeric label of the vertices.
