Identify two related tables in the JustLee Books database. Identify the common field between the two tables. Decide which columns you would like to display in the output. Write a SQL code to join identified tables using the WHERE statement. Make sure to include qualifiers for columns that appear in both tables. Since only two tables are joined, make sure to include one join condition in the WHERE statement. Explain what the query is intended to do.

Repeat problem 1 but remove the WHERE statement. What happened? Why?

Repeat problem 1 using the JOIN … USING keywords.

Repeat problem 1 using the JOIN … ON keywords.

Repeat problem 1 but add a condition in the WHERE statement. Use logical operators to combine multiple conditions. Explain what the query is intended to do.

Repeat problem 1 but add two more conditions in the WHERE statement. Use logical operators to combine multiple conditions. Explain what the query is intended to do.

Identify three related tables in the JustLee Books database. Identify common fields between the tables. Decide which columns you would like to display in the output. Write a SQL code to join identified tables using the WHERE statement. Make sure to include qualifiers for columns that appear in multiple tables. Since three tables are joined, make sure to include two join conditions in the WHERE statement. Explain what the query is intended to do.

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e. g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
