Relational Database (1 of 4)
Definition
● Relational Database is database that all data are
established many tables to have relationship each
other.
● Each table consists of many columns and many rows
that each column is usually called a register,each row
is described an attribute.

3

The main components
● The main components :
 Table: each table stores information of an object
outside real life.
 Primary key: a collection of one column or many
columns inside tables that it is not permit null data and
is only one.
 Foreign key: a collection of one column or many
columns inside tables that they are a primary of other
tables and their data can be permitted null

Database Management System(1 of 3)

● Popular Database Management Systems
 MS SQL server
 MySQL
 Oracle
 PostgreSql
 DB2
 …

Database Management System(2 of 3)
Definition
● Database management system is a
software to permit users to create,
control and access into database.
● Database management system has
maintained consistency of database
during its cycle life.

8

Database Management System (3 of 3)
Function
● The main functions of database management system
 Database definition
 Database construction
 Database manipulation: add , delete...
 Database administrator: security...
 Database protection: backup, restore

Mircosoft SQL server(1 of 3)
● MS SQL Server is a database management
system that it is established and developed by
Microsoft based on Transact-SQL method in
order to exchange data between Client and MS
SQL Server.

10

Adaptation
● MS SQL Server is optimized in order to run Very
Large Database Environment (VLDE) even
though Tera-Byte, especially for serving user
thousands
● MS SQL Server can collaborate with other
servers such as Microsoft Internet Information
Server (IIS), Oracle...

11

Versions
● Versions of MS SQL Server
 Enterprise Edition
 Developer Edition
 Standard Edition
 Workgroup Edition
 SQL Server Express Edition

12

Structure
● One of the most usual structures MS SQL Server
 Client / Server Architecture
 N-tier Architecture

How to create index for each record(1 of 2)

● Index is used to supporting and improving
for accessing more quick to data flows base
on value of one or many columns.
● Two forms:
 Clustered index
 Non-clustered index

16

How to create index for each record(2 of 2)

● Syntax:
CREATE [CLUSTERED | NONCLUSTERED] INDEX index_name
ON table_name(column_name [, column_name]...)

● For example for creating non-clustered index on
MADV of NHANVIEN columns:
CREATE NONCLUSTERED INDEX idx_nhanvien_madv
ON nhanvien(madv)

17

Backup, Restore Database(1 of 7)
Backup
What is Backup Database?
● That is the activity of copying files or
databases from SQL server to another
storage device.
● Having two backup database forms:
 By backup database commands
 By direct action in your SQL Server

18

Backup
Syntax of Backup Database Commands
BACKUP DATABASE { database_name | @database_name_var }
TO < backup_device > [ ,...n ]
[ WITH
[ BLOCKSIZE = { blocksize | @blocksize_variable } ]
[ [ , ] DESCRIPTION = { 'text'| @text_variable } ]
[ [ , ] DIFFERENTIAL ]
[ [ , ] EXPIREDATE = { date | @date_var }
| RETAINDAYS = { days | @days_var } ]
[ [ , ] FORMAT | NOFORMAT ]
[ [ , ] { INIT | NOINIT } ]
[ [ , ] MEDIADESCRIPTION = { 'text'| @text_variable } ]
[ [ , ] MEDIANAME = { media_name | @media_name_variable } ]
[ [ , ] NAME = { backup_set_name | @backup_set_name_var } ]
[ [ , ] { NOSKIP | SKIP } ]
[ [ , ] { NOUNLOAD | UNLOAD } ]
[ [ , ] RESTART ]
[ [ , ] STATS [ =percentage ] ]
]

19

Backup
Description
° BLOCKSIZE: automatic parameter
° DIFFERENTIAL: differential backup is only
necessary change datas
° EXPIREDATE: expiration of backup day
° FORMAT/NOFORMAT: destroying existing datas
or not
° INIT/NOINIT: replace datas or not
° DESCRIPTION: details of description
° STATS: appearance of programbar
20

Backup
For example backup database
BACKUP DATABASE QLNGK
TO DISK= ‘F: ngk.bak’
WITH
DESCRIPTION = ‘BACK UP’,
STATS
GO

21

Backup
Result

22

Restore
Syntax
RESTORE DATABASE { database_name | @database_name_var }
[ FROM <backup_device> [ ,...n ] ]
[ WITH {
[ RECOVERY | NORECOVERY | STANDBY =
{standby_file_name | @standby_file_name_var } ]
| , <general_WITH_options> [ ,...n ] | , <replication_WITH_option>
| , <change_data_capture_WITH_option> | , <service_broker_WITH options>
| , <point_in_time_WITH_options—RESTORE_DATABASE>
} [ ,...n ]
]
[;]
23

Backup, Restore Database(end)
Restore
For example:
RESTORE DATABASE users
FROM DISK='C:backupusers.BAK'
WITH RECOVERY

24

Stored Procedure, Trigger (1 of 9)
Stored Procedure
What is Stored Procedure ?
● SP (Stored Procedure) is the name given to a
group of SQL statement is created and stored in
the server database.
● SP allows transmission parameters, and may be
called by many clients over the network with
different parameters. When SP is changed, all
clients will automatically receive the new
version, because the SP is stored at the Server,
not Client.

25

Stored Procedure
Creating procedure
CREATE PROCEDURE procedure_name [;number]
[([parameter1] [,parameter2]...[parameter255])]
AS sql_statements

26

Stored Procedure
For example
CREATE PROCEDURE sp_users_insert

(@firstname varchar(50),

@lastname varchar(50),

@birthday date,

@groupid int)

AS

BEGIN

if exists(select groupid from groups where groupid = @groupid)

BEGIN

insert into users(firstname, lastname, birthday, groupid)
values(@firstname,@lastname,@birthday,@groupid)

END

END
27

Trigger
● Trigger is a data type that is specific saved.
Otherwise, trigger to help ensure data integrity.
● A table has maximum 3 trigger types:
 Update trigger
 Insert trigger
 Delete trigger
● For example: employer salary is not permitted
higher than his top-banana

28

Trigger
Syntax:
CREATE TRIGGER trigger_name
ON table_name | view_name
[WITH ENCRYPTION]
{FOR | AFTER | INSTEAD OF}{ [INSERT] [,] [UPDATE ] [,]
[DELETE] }
AS sql_statements

29

Trigger

CREATE TRIGGER groups_users_delete
on groups
for delete
as
BEGIN
DECLARE @groupid int;
Set @groupid=(Select groupid from DELETED);
delete from users where groupid = @groupid
END

30

Function
Function is database object similar procedures .
However,the difference between procedures and
function that function returns to a value via its
function name while procedures do not.

31

Trigger
Syntax
CREATE FUNCTION [ schema_name. ] function_name
( [ { @parameter_name [ AS ]
[ type_schema_name. ] parameter_data_type
[ = default ] [ READONLY ] }
[ ,...n ]S
]
)
RETURNS return_data_type
[ WITH <function_option> [ ,...n ] ]
[ AS ]
BEGIN
function_body
RETURN scalar_expression
END
[;] 32

Stored Procedure, Trigger (end)
Trigger
For example
CREATE FUNCTION f_users_tong()
RETURNS @bangthongke TABLE
(groupid int,groupname varchar(50),tonguser INT)
AS
BEGIN
INSERT INTO @bangthongke
SELECT groups.groupid,groups.groupname,COUNT(userid)
FROM (groups INNER JOIN users
ON groups.groupid = users.groupid)
GROUP BY groups.groupid,groups.groupname
RETURN
END

33

View(1 of 4)

Definition
● View is a method that we can watch at data into
one or many tables of database.
● View is a virtual screen that it is created as a union
of rows and columns by one or many different
tables.
● Decreasing more complex in database

34

View(2 of 4)

Syntax:
CREATE VIEW COMMAND used to create view:

CREATE VIEW <virtual_name_table>
AS
<select_statement>

35

View(3 of 4)

For example:
CREATE VIEW DSSV
AS
SELECT masv, hodem, ten,
DATEDIFF (YY, ngaysinh,GETDATE())
AS tuoi, tenlop
FROM sinhvien, lop

36

View(end)
Result
