Normalization: The process used to minimize data redundancy and dependency in a relational database is known as normalization. The database table is divided into two or more tables and defines the relationship between those tables. Third normal form (3NF): The value of any non-primary key attributes will not depend on any other non-primary key attributes. If any non-primary key attributes depend on any other non-primary key attribute then it should be moved or deleted. It is termed as transitive dependency. Partial dependency: A partial dependency exists at that time of an attributes depends only a part of primary key. This dependency is related with 1 st normal form. Transitive dependency: A transitive dependency exists at that time of an attributes depends on another attribute which is not part of primary key. Functional dependency: An association between two attributes or two set of attributes in a same relational database table, which is having some constraints is known as functional dependency. In a table one attribute is functionally dependent on another attribute to take one value.

Consider the problem of finding a path in the grid shown below from the position S to theposition G. The agent can move on the grid horizontally and vertically, one square at atime (each step has a cost of one). No step may be made into a forbidden crossed area.

Chapter 6, Problem 1P

Program Plan Intro

Normalization:

The process used to minimize data redundancy and dependency in a relational database is known as normalization. The database table is divided into two or more tables and defines the relationship between those tables.

Third normal form (3NF):

The value of any non-primary key attributes will not depend on any other non-primary key attributes.

If any non-primary key attributes depend on any other non-primary key attribute then it should be moved or deleted.

It is termed as transitive dependency.

Partial dependency:

A partial dependency exists at that time of an attributes depends only a part of primary key. This dependency is related with 1^st normal form.

Transitive dependency:

A transitive dependency exists at that time of an attributes depends on another attribute which is not part of primary key.

Functional dependency:

An association between two attributes or two set of attributes in a same relational database table, which is having some constraints is known as functional dependency.

In a table one attribute is functionally dependent on another attribute to take one value.

Consider the follow program that prints a page number on the left or right side of a page. Define and use a new function, isEven, that returns a Boolean to make the condition in the if statement easier to understand. ef main() : page = int(input("Enter page number: ")) if page % 2 == 0 : print(page) else : print("%60d" % page) main()
