12. 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 usuallycalled a register,each row is described an attribute. 3

14. Primary key: a collection of one column or many columns inside tables that it is not permit null data and is only one.

15. 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 null4

24. 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

26. Database construction

27. Database manipulation: add, delete...

28. Database administrator: security...

29. Database protection: backup, restore9

30. 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

31. Mircosoft SQL server(2 of 3)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

42. Non-clustered index16

43. How to create index for each record(2 of 2) Syntax: CREATE [CLUSTERED | NONCLUSTERED] INDEXindex_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 ONnhanvien(madv) 17

45. Having two backup database forms:

46. By backup database commands

47. By direct action in your SQL Server18

48. Backup, Restore Database(2 of 7)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

50. DIFFERENTIAL: differential backup is only necessary change datas

51. EXPIREDATE: expiration of backup day

52. FORMAT/NOFORMAT: destroying existing datas or not

53. INIT/NOINIT: replace datas or not

54. DESCRIPTION: details of description

55. STATS: appearance of programbar20

56. Backup, Restore Database(4 of 7)Backup For example backup database BACKUP DATABASE QLNGKTO DISK= ‘F:ngk.bak’WITH DESCRIPTION = ‘BACK UP’,STATS GO 21

57. Backup, Restore Database(5 of 7)Backup Result 22

58. Backup, Restore Database(6 of 7)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

59. Backup, Restore Database(end)Restore For example: RESTORE DATABASE users FROM DISK='C:ackupusers.BAK' WITH RECOVERY 24

61. 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

62. Stored Procedure, Trigger (2 of 9)Stored Procedure Creating procedure CREATE PROCEDURE procedure_name [;number] [([parameter1] [,parameter2]...[parameter255])] AS sql_statements 26

63. Stored Procedure, Trigger (3 of 9)Stored Procedure For example CREATEPROCEDURE sp_users_insert (@firstname varchar(50), @lastname varchar(50), @birthday date, @groupid int) AS BEGIN ifexists(select groupid from groups where groupid = @groupid) BEGIN insertinto users(firstname, lastname, birthday, groupid)values(@firstname,@lastname,@birthday,@groupid) END END 27

65. Insert trigger

66. Delete triggerFor example: employer salary is not permitted higher than his top-banana 28

67. Stored Procedure, Trigger (5 of 9)Trigger Syntax: CREATE TRIGGER trigger_name ON table_name | view_name [WITH ENCRYPTION] {FOR | AFTER | INSTEAD OF}{ [INSERT] [,] [UPDATE ] [,] [DELETE] } AS sql_statements 29

68. Stored Procedure, Trigger (6 of 9)Trigger CREATE TRIGGER groups_users_delete on groups fordelete as BEGIN DECLARE @groupid int; Set @groupid=(Select groupid from DELETED); deletefrom users where groupid = @groupid END 30

69. Stored Procedure, Trigger (7 of 9)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

70. Stored Procedure, Trigger (8 of 9)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

71. Stored Procedure, Trigger (end)Trigger For example CREATEFUNCTION f_users_tong() RETURNS @bangthongke TABLE (groupid int,groupname varchar(50),tonguser INT) AS BEGIN INSERTINTO @bangthongke SELECT groups.groupid,groups.groupname,COUNT(userid) FROM (groups INNERJOIN users ON groups.groupid = users.groupid) GROUPBY groups.groupid,groups.groupname RETURN END 33

73. View is a virtual screen that it is created as a union of rows and columns by one or many different tables.

74. Decreasing more complex in database34

75. View(2 of 4) Syntax: CREATE VIEW COMMAND used to create view: CREATE VIEW <virtual_name_table> AS <select_statement> 35

76. View(3 of 4) For example: CREATE VIEW DSSV AS SELECT masv, hodem, ten, DATEDIFF (YY, ngaysinh,GETDATE()) AStuoi, tenlop FROMsinhvien, lop 36

77. View(end) Result 37
