3. Assume the following indexes exist:
• A hash index with no overflow on the primary key attributes, roomNo/hotelNo in Room;
• A clustering index on the foreign key attribute hotelNo in Room;
• A B+-tree index on the price attribute in Room;
• A secondary index on the attribute type in room

 nTuples (Room) = 10,000 bFactor(Room) = 200
 ntuples(Hotel) = 50 bFactor9Hotel) = 40
 nTuples(Booking) = 100,000 bFactor(Booking) = 60
 nDistincthotelNo(Room) = 50
 nDistinctType(Room) =10
 nDistinctprice(Room) = 500
 minprice (Room) = 200 maxprice(Room) = 50
 nLevelshotelNo(I) = 2
 nLevelsprice(I) = 2 nLFBlocksprice(I) = 50
Calculate the cardinality and minimum cost for each of the following selection operations
S1:  roomNo = 1  hotelNo =’H001’(Room)
S2: type’D’ (Room)
S3: hotelNo’H002’(Room)
S4: price > 100 (Room)
S5: type’S’  hotelNo = ‘H003’(Room)
S6: type’S’ price < 100 (Room)

join between two table with one too many relationship is faster or join between two table without relationship is faster

Build a working sample of Huffman Trucking’s fleet truck maintenance database.

Use the CREATE table statement to create a table for each entity for Huffman Trucking’s fleet truck maintenance database.

Use the INSERT statement to populate the tables with realistic sample data, demonstrating each relationship in your entity relationship diagram. Include at least two entries for each table.

Use the SELECT statement to create the following queries:

• Create a simple query for each table that returns all of the columns and all of the rows for each table.

• Write a query that displays each part that has been purchased by Huffman Trucking Company. For each part, also retrieve its parts catalog information from the parts catalog table and vendor information from the vendor table.

• Write a query that displays all of the rows in the vehicle maintenance table. For each vehicle maintenance row, join the corresponding information from the maintenance descriptions table and vehicles table.

• Write a query that displays each row in the maintenance work order table. For each row in the maintenance work order table, join the corresponding information from the maintenance description table.

• Write a query that counts the number of maintenance work orders for each vehicle in the maintenance work order table. Display the vehicle column and the corresponding count of work orders for each vehicle.

Use Reporting Services to design and create a report on the parts purchasing history for Huffman Trucking Company. The report should display all parts purchasing history including manufacturer and vendor information, parts catalog information, and associated parts inventory issues, and all parts inventory purchases.

Format the report to present to senior management at Huffman Trucking.

List the team names and the total number of players from the team who played less than 20 minutes on the ground in the last two years (the current year and last year). The season attribute in the database is VARCHAR(5) to allow for sports which run multiple seasons within a calendar year, such seasons are coded as, for example: 2001S, 2001W (note that the first four characters are always the year). Name the columns as 'TEAM NAME' and 'LESS THAN 20 COUNT'. Sort the output according to the 'LESS THAN 20 COUNT' column, teams with have the same count should be ordered by team name.
