- 12. Relational Database (1 of 4)DefinitionRelational 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
- 13. Relational Database (2 of 4)The main componentsThe main components:Table: each table stores information of an object outside real life.
- 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)DefinitionDatabase 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
- 25. Database Management System (3 of 3)FunctionThe main functions of database management systemDatabase definition
- 27. Database manipulation: add, delete...
- 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)AdaptationMS 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

- 41. 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
- 43. How to create index for each record(2 of 2)Syntax:CREATE [CLUSTERED | NONCLUSTERED] INDEXindex_nameON table_name(column_name [, column_name]...)For example for creating non-clustered index on MADV of NHANVIEN columns:CREATE NONCLUSTERED INDEX idx_nhanvien_madvONnhanvien(madv)17
- 44. Backup, Restore Database(1 of 7)BackupWhat is Backup Database?That is the activity of copying files or databases from SQL server to another storage device.
- 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)BackupSyntax of Backup Database CommandsBACKUP 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
- 49. Backup, Restore Database(3 of 7)BackupDescriptionBLOCKSIZE: automatic parameter
- 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)BackupFor example backup databaseBACKUP DATABASE QLNGKTO DISK= ‘F:\ ngk.bak’WITH DESCRIPTION = ‘BACK UP’,STATS GO21
- 57. Backup, Restore Database(5 of 7)BackupResult22
- 58. Backup, Restore Database(6 of 7)RestoreSyntax 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)RestoreFor example: RESTORE DATABASE users FROM DISK='C:\backupusers.BAK' WITH RECOVERY24
- 60. Stored Procedure, Trigger (1 of 9)Stored ProcedureWhat is Stored Procedure ?SP(Stored Procedure) is the name given to a group of SQL statement is created and stored in the server database.
- 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 ProcedureCreating procedureCREATE PROCEDURE procedure_name [;number] [([parameter1] [,parameter2]...[parameter255])] AS sql_statements26
- 63. Stored Procedure, Trigger (3 of 9)Stored ProcedureFor 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) BEGINinsertinto users(firstname, lastname, birthday, groupid)values(@firstname,@lastname,@birthday,@groupid) END END27
- 64. Stored Procedure, Trigger (4 of 9)TriggerTrigger is a data type that is specific saved. Otherwise, trigger to help ensure data integrityA table has maximum 3 trigger types:Update trigger
- 65. Insert trigger
- 66. Delete triggerFor example: employer salary is not permitted higher than his top-banana28
- 67. Stored Procedure, Trigger (5 of 9)TriggerSyntax:CREATE TRIGGER trigger_name ON table_name | view_name [WITH ENCRYPTION] {FOR | AFTER | INSTEAD OF}{ [INSERT] [,] [UPDATE ] [,] [DELETE] } AS sql_statements29
- 68. Stored Procedure, Trigger (6 of 9)TriggerCREATE TRIGGER groups_users_deleteon groupsfordeleteasBEGINDECLARE @groupid int;Set @groupid=(Select groupid from DELETED);deletefrom users where groupid = @groupidEND30
- 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)TriggerSyntaxCREATE 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)TriggerFor exampleCREATEFUNCTION 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 END33
- 72. View(1 of 4)DefinitionView is a method that we can watch at data into one or many tables of database.
- 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 DSSVAS SELECT masv, hodem, ten,DATEDIFF (YY, ngaysinh,GETDATE())AStuoi, tenlopFROMsinhvien, lop36
