1 SQL Server Database Administration and Design By Dave Peru, October 2011 Introduction Name Handout Sheet Developer s Perspective - Story Outline Create a Database Create a New Data Model Data Model Diagrams Relationships and Indexes SQL Server Account Security SQL Scripts Moving Database Files Create Web Pages for Editing Database CSS Files and Data Entry Forms Database Backups SQL Server Agent 1

2 Create a Database Launch SQL Server Management Studio Enter MyDatabase, click OK: 2

3 Right click over Tables, select New Table from the popup menu: Create Table1: Set Primary Key: Save Table 1 : Close workspace windows, <ctrl-f4>, <ctrl-f4> 3

4 Right click over Tables, select New Table from the popup menu: Create Table 2: Save Table 2 : Close workspace windows, <ctrl-f4> Expand Tables folder: 4

5 Create a New Data Model Expand Database Diagrams folder: Click Yes. Right click over Database Diagrams folder, add new diagram: Select both tables, click Add: Click Close, position tables, change view: 5

6 Change view on Table 2, your diagram should look like the following: Database Relationships Graphical user interfaces and hidden handshakes: Click OK, OK, adjust relationship object: Reason for Relationships, Software Service Providers, Amazon S3, lost data VoltDB massively large distributed databases with relationship integrity Lost data, Jay from J & J Story 6

7 Database Indexes Increase Speed Data Model Diagrams Right click over the spot, select menu item: Click Add: Click Close, Click : Then click Yes: 7

8 Printing Data Model Diagrams Print Problems, Select Copy Diagram to Clipboard: Launch Word, expand margins, paste: Show Buzz diagram: 8

9 SQL Server Account Security Expand Security folder in Object Explorer, right click over Logins, New Login: Fill out the form for user1 : Click OK to continue. 9

10 Right click Users folder under Security under MyDatabase: Click on the eclipses: Enter user1, click on the Check Names button, then click OK: File out user1 for the User name field, then click on OK again: 10

11 Expand the Schemas folder, right click over dbo and select Properties menu: Go to the Permissions tab: Click on the Add button, enter user1, click Check Names, click OK: Select the access rights as follows and click OK: 11

12 Working with SQL Scripts, Start in MyDatabase / Security / Users You should see the following: Select File Save As menu: Create new directory c:\demo1\sql : 12

13 From MyDatabase Security Logins, script to clipboard the following: You will see the following: Click on the button to run the script. You should see the following result: Recreate user1 access to database: 13

14 Select Script Action To Clipboard: Paste into our script file: Add user1 as user of MyDatabase, script to clipboard, paste into script: Right click over dbo, select Properties from popup menu: Select access rights, script to clipboard: 14

15 Paste into our script file. Click on the the following result: button to run the script. You should see Verify user1 exists and has the correct access rights: Moving Database Files Good Object Oriented Design for Code and Data Detach Database 15

16 Find database files, and cut to clipboard: Navigate to c:\demo1, create Database Files folder, paste files to new location: Return to SQL Server Management Studio 16

17 Attach Database: Navigate to c:\demo1\database Files and select MDB file: Database is back, but user1 account is now invalid, run our script: 17

18 Select c:\demo1\sql\ DropCreateUser1.sql : Exit SQL Server Management Studio Create Web Pages for Editing Our Database Launch Visual Studio: Select New / Web Site menu item: Select c:\demo1\website1 for the location, then click OK: 18

19 Create a new solutions file for project settings. Select the solution root inside Solution Explorer: Next, select file Save As menu item: 19

20 In the c:\demo1\sln folder, save the website1.sln file: Time to prepare to run a program generator called Mintiera. Mintiera will create web pages we can use to edit records in our database. Delete App_Data folder: Delete Default.aspx file: 20

21 Use Visual Studio Import Feature. Create App_Code folder: Create Admin folder: Create css folder. Create Javascript folder. You should see the following: 21

22 Mintiera web site: Mintiera is code generator: Web pages, CSS friendly user controls, middle tier data access components, for editing records in a database The way Mintiera works: 10 SQL data types cross 20 code snippets for CRUD Northwind Data Model: Editing the Northwind data base: 22

23 Running Mintiera on MyDatabase: Click on Aready Registered, Login link: Mintiera uses Click-Once deployment, click button to launch program: Enter Connection Parameters and click Next button: Use defaults for Layer Options, click Next button: 23

24 Copy Connection String text into clipboard: Return to Visual Studio. Edit web.config file: Return to Mintiera, select Table1 and click Next button: 24

25 Default values for SQL field types determined from data model. Use defaults, click Next: Default values key generation method determined by field type, click Next button: 25

26 Default values for related tables taken from data model, click Next button: Mintiera supports 4 levels of data validation: Client-Side Javascript, web page presentation layer, middle tier data access component, and database validation. Default values for related tables taken from data model, click Next button: 26

27 You must specify a temporary folder for output (c:\tmp shown below): Click Generate Code button to create about 4000 lines of code: 27

28 Click Restart button and select Table2, click Next button: Use Mintiera defaults for Field Types and options, click Next button: 28

29 Select the following for Table2 Primary and Foreign Key Settings, click Next: Use Mintiera defaults for related tables, click Next: Use defaults for Validation Settings, click next button: 29

30 Click Generate Code button for Output Settings: Click Exit button when code generation is complete: 30

31 Next, we need to import the generated Mintiera code into our Visual Studio project. Right click over Admin folder in Solution Explorer, and select Add Existing Item: Select all the files in c:\tmp\webforms2 as shown: We just added all the web pages we need to edit MyDatabase. 31

32 Right click over the App_Code folder, select Add Existing Items from the popup: Select all the files in c:\tmp\app_code folder to import all the middle tier data access components: Again, right click over the App_Code folder, select Add Existing Items from the popup. And import all the App_Code_Support_Classes to Visual Studio: 32

33 Right click over the css folder, select Add Existing Items from the popup: Import all the files from c:\tmp\css : Right click over the Javascript folder, select Add Existing Items from the popup: 33

34 Import all the files from c:\tmp\javascript : Right click over the root folder, select Add Existing Items from the popup: Import all the files from c:\tmp\ GlobalApplicationCode : Add a reference to System.Design: 34

35 Select Build Solution from the Build menu: Confirm Build succeeded: Return to SQL Server Management Studio. Select File / Open / File menu: 35

36 Table1Script.sql and Table2Script.sql contain SQL script for stored procedures used by middle tier data access components for doing CRUD operations. Navigate to c:\tmp\sql, select all files, click on the Open button: Click <F5> to execute: Click <F4> to close the window, click <F5> to execute the next SQL script: 36

37 Click <F4> to close the window, exit the management studio, return to Visual Studio. Set MyDatabase.aspx as the start page for Visual Studio. Hit <ctrl-f5> to launch brower: Show web pages for editing records. 37

38 CSS Files and Data Entry Forms Mintiera uses a table-less web page design for page layout. No HTML-table tags. Table tags auto fill versus div-tag liquid fill. This OuterDiv-InnerDiv CSS method works with the following browsers (no hacks): IE 6, IE 7, IE 8 regular mode, IE 8 compatibility mode Firefox 3, Opera 9, Safari 3, and Google Chrome 4 The method uses only CSS to control layout. Content is separated from presentation. Remove the CSS file and you see the following: CSS friendly controls can be modified for data entry forms. Restore CSS files and layout returns: 38

39 The idea of separating content from presentation is illustrated by CSSZenGarden.Com Database Backups 39

40 Remove default backup file: Click on Add button, select file and location, click on OK button: Click on the Options button, select Overwrite all existing backup sets, Click OK: 40

41 Once completed, you will see the following: SQL Server Agent Start SQL Server Agent if not running: 41
