- Write a PHP script that obtains a URL and its description from a user and stores the infor- mation into a database using MySQL. Create and run a SQL script with a database named URL and a table named Urltable. The first field of the table should contain an actual URL, and the second, which is named Description, should contain a description of the URL. Use www.deitel.com as the first URL, and input Cool site! as its description. The second URL should be www.php.net, and the description should be The official PHP site. After each new URL is submitted, print the con- tents of the database in a table. [Note: Follow the instructions in Section 18.5.2 to create the Urldatabase by using the URLs.sql script that’s provided with this chapter’s examples in the dbscripts folder.]In the variable-length record representation, a null bitmap is used to indicate if an attribute has the null value. a. For variable length fields, if the value is null, what would be stored in the offset and length fields? b. In some applications, tuples have a very large number of attributes, most of which are null. Can you modify the record representation such that the only overhead for a null attribute is the single bit in the null bitmap.Each student record in the data area where pupil information is stored has the following format:The student ID is stored in the first nine bytes in ASCII.The course stamp is the following byte.The section number comes after that. Such student records have been sequentially loaded into memory starting at address $10000 and number well over 300. A fake record with the section identifier $FFFF is the last record to load, indicating the conclusion of the records. Create the GetMax assembler subroutine to search the entire list for the highest score. In the event of a tie, the top pupil on the list should be identified. the beginning address of the subroutine should
