Chapter 3, Problem 11RQ
Program Plan Intro
A database is a structure that is used to hold data and it referred as a systematic collection of data.
Table:
A table is a logical structure that represents an entity state. It is one of the components of database.
One to Many Relationship:
When one record in a database table is associated with more than one record in another table, the relationship between the two tables is referred as one to many relationship. It is also represented as1: M relationship. This is the opposite of many to one relationship.
CROW FOOT ERD:
The Crow Foot ERD is an Entity Relationship Diagram which is used to represent the cardinalities present in the basic ER diagram. It is used to represent the relationships present between two tuples or tables present in the database.

Programming Problems
9.28
Assume that a system has a 32-bit virtual address with a 4-KB page size.
Write a C program that is passed a virtual address (in decimal) on the
command line and have it output the page number and offset for the
given address. As an example, your program would run as follows:
./addresses 19986
Your program would output:
The address 19986 contains:
page number = 4
offset = 3602
Writing this program will require using the appropriate data type to
store 32 bits. We encourage you to use unsigned data types as well.
Programming Projects
Contiguous Memory Allocation
In Section 9.2, we presented different algorithms for contiguous memory allo-
cation. This project will involve managing a contiguous region of memory of
size MAX where addresses may range from 0 ... MAX - 1. Your program must
respond to four different requests:
1. Request for a contiguous block of memory
2. Release of a contiguous block of memory
3. Compact unused holes of memory into one single block
4.…
