SQL Server Question and Answear

1Question : Identify the advantages of a Network Database Model.

a)    The relationships are easier to implement
b)    The databases are easy to design
c)    The model enforces database integrity
d)    The model achieves sufficient data independence.
e)    All of the above
Correct Answers : acd      //e http://wiki.answers.com/Q/The_advantages_and_disadvantages_of_database_network_model
2 Question : The __________ component is used to administer permissions on the databases and database objects.

f)    DML
g)    sub-schema DDL
h)    DCL
i)    DDL
Correct Answers : c
http://blog.sqlauthority.com/2008/01/15/sql-server-what-is-dml-ddl-dcl-and-tcl-introduction-and-examples/
3 Question : Which of the following statement/s with respect to the Relational Model is/are True?

j)    This model hides all the complexities of the system
k)    This model is much faster than the other database systems
l)    This model concentrates more on the logical view of the database rather than the physical view.
m)    This model offers a great deal of querying flexibility
n)    This model is very easy to handle.
Correct Answers : acde //in book page no 16
The fastest database modle is network database modle
4 Question : The Entity integrity rule states that no component of the primary key of a base table should be allowed to accept NULL values. Do you agree with this statement?

o)    Yes. Because, if the primary key contains NULL values, then the rows would no longer be unique.
p)    No. The primary key can contain NULL values but not a zero.
q)    Can't say.
Correct Answers : a
Very easy
5 Question : Statement 1: For a column to be set as a foreign key in a given table, it must be a primary key in another table.
Statement 2: The two columns being joined by the foreign key relationships must have an identical definition.

r)    Only statement 2 is True
s)    Both the statements are True
t)    Both the statements are False
u)    Only statement 1 is True
Correct Answers : b
So easy
6 Question : Which of the following statements with respect to Referential Integrity and Foreign Keys are NOT TRUE?

v)    A database must not contain more than one unmatched foreign key value.
w)    The attribute values in the foreign key must have a corresponding match in the relation where the attribute is a primary key.
x)    New values cannot be introduced in a foreign key
y)    None of the above
Correct Answers : a
7 Question : Who am I?
I am used for efficient searching through a database.
I am used to build online libraries
